INTRODUCTION


On behalf of the faculty and staff, I want to welcome each of you to the
Gulf Coast Research and Education Center, at Bradenton, Florida. This
Center was initiated in 1925 as the Tomato Disease Laboratory (a one-man
operation in Palmetto), and the first ornamental programs began about 17
years later. This Center, with the affiliated Agricultural Research and
Education Center in Dover, is a Research and Education unit of the
University of Florida's Institute of Food and Agricultural Sciences.

In Bradenton, we have two grant-supported scientist positions, three
Extension Specialist positions, and 16 state research scientists from
various disciplines of training who participate in all phases of vegetable
and ornamental horticulture. This interdisciplinary team approach,
combining several research disciplines and a wide range of industry and
faculty contacts, often is more productive than could be accomplished with
limited investments in independent programs.

The Center's primary mission is to develop new and expand existing
knowledge and technology, and to disseminate new scientific knowledge on
vegetable and ornamental crops in Florida, so that agriculture remains
efficient and economically sound.

The secondary mission of the Center is to assist the Cooperative Extension
Service, IFAS campus departments in which Center faculty hold appropriate
liaison appointments, and other research centers in extension, educational
training, and cooperative research programs for the benefit of Florida's
producers, students and citizens.

Program areas of emphasis include: (1) genetics, breeding, and varietal
development and evaluation; (2) biological, chemical, and mechanical pest
management for diseases, insects, nematodes, and weeds; (3) production
efficiency, culture, management of environmental stress; (4) water
utilization, quality, conservation, and management; (5) food quality,
safety, utilization and post-harvest physiology of horticultural crops; (6)
air, water, and land management; (7) mechanization, harvesting, handling,
and engineering; (8) energy conservation techniques and alternate energy
sources; (9) advancement of the basic knowledge in disciplines; (10)
regional and state cooperative extension programs and public service; and
(11) student advisement and teaching.

Information presented in this publication summarizes the active research
projects under way this season on vegetable crops. We sincerely appreciate
your interest and support of these research programs, and continuously
solicit your suggestions for improvement of our research and extension
programs.

HISTORY OF THE GULF COAST RESEARCH & EDUCATION CENTER


The University of Florida's Gulf Coast Research and Education Center in
Bradenton originated in the fall of 1925 with construction of the Tomato
Disease Laboratory.

Tomato Disease Laboratory: In 1925, a 20-acre tract of county-owned
property in Palmetto was made available with the cooperation of the Manatee
County Board of Commissioners with money and equipment supplied by local
growers. The primary objective of the laboratory was to formulate a
control for nailhead spot of tomatoes. Later studies emphasized the
breeding for resistance to Fusarium wilt and the control of tobacco mosaic
virus on tomatoes. In 1937, with the expansion of the vegetable industry
in Manatee County and surrounding areas, the state legislature authorized
new facilities for the research program.

Vegetable Crops Laboratory: In August 1938, the Manatee County
Commissioners donated 80% of the purchase price of a 106-acre tract of land
on the east side of Bradenton. This expanded program led to the
establishment of the Vegetable Crops Laboratory. Following this
relocation, horticultural, entomological and soil studies were initiated on
tomatoes, peppers, lettuce, sweet corn and other vegetables. Since the
laboratory was located in the gladiolus growing area, the scope was further
broadened in 1942 to include disease problems confronting gladiolus
growers.

Gulf Coast Experiment Station: In March 1951 at a meeting of the State
Board of Control, the Vegetable Crops Laboratory was given the status of a
branch station and was renamed the Gulf Coast Experiment Station.
Investigations were then initiated dealing with chemical weed control,
nematodes and other soil-borne pests. The ornamental phase was broadened
to include chrysanthemums and other commercial cut flowers.

In the late 1950's it became apparent that the facilities on the outskirts
of Bradenton were no longer adequate for the research program. In 1959 a
200-acre tract of land was acquired eight miles east of Bradenton. All of
the vegetable experimental field programs were moved to this location.

In 1965, upon completion of the construction of office and laboratory
facilities, farm buildings, greenhouses and a residence, all research
programs were conducted at this new site.

Agricultural Research and Education Center-Bradenton: In 1971 the Gulf
Coast Experiment Station was renamed the Agricultural Research and
Education Center to emphasize the programs of both research and education.
During the next 14 years the Center research and extension programs were
broadened and the physical plant expanded.

Gulf Coast Research and Education Center: In 1984 the Agricultural
Research and Education Center in Bradenton was renamed the Gulf Coast
Research and Education Center (GCREC) to emphasize the regional status of
the Center. The GCREC has administrative and research supervision over one
other Research Center the Agricultural Research and Education Center in
Dover which specializes in strawberry research.

PEPPER WEEVIL SAMPLING ON PEPPER


D. Riley, D. J. Schuster

Location: Block B, Land 4, 5

Objective: To study the diurnal and spatial distributions of pepper weevil
adults in order to develop an improved sampling method.

Crop: Pepper, cv. Jupiter, transplanted Feb. 26, 1987.

Operation: At least 50 plants will be selected weekly on a stratified
random basis. This will ensure that all areas of the field are sampled.
Each plant will be visually inspected every daylight hour. The number of
adults will be recorded according to their location on the plants:
terminals, stems, young leaves and old leaves.

Summary: In a previous experiment in Honduras, the mean number of adult
pepper weevils was greatest on pepper terminals at 0800, 0900 and 1000
hours than at others times. We will determine where the weevils are
located at other time intervals. This information will enable scouts to
better sample peppers for weevil adults at times other than 0800, 0900 and
1000.

IMPACT OF COPPER BACTERICIDES ON CONTROL OF LEPIDOPTEROUS LARVAE

D. J. Schuster, J. B. Jones

Location: Block B, Land 5

Objective: To evaluate the impact of copper compounds on the survival of
armyworm caterpillars and their damage on tomato.

Crop: Tomato, cv. Sunny; transplanted Feb. 24, 1987.

Treatments: 1. Check (water)
2. Copper Count N (3 qt)
3. Tribasic Copper Sulfate (4 lb)
4. Tribasic Copper Sulfate (2 Ib)
5. Kocide 101 (4 lb)
6. Kocide 101 (2 lb)

Operation: Treatments will be applied weekly beginning about 2-3 weeks
after transplanting. The number of caterpillars will be counted every 2
weeks. Larvae will be collected, reared in the laboratory and observed for
survival and disease incidence. The number of caterpillar damaged fruit
will be counted at harvest.

Summary: In previous experiments, the application of certain copper
compounds has resulted in more fruit damaged by lepidopterous larvae.
However, this has not been consistent in all seasons. The compounds may
1) not be affecting caterpillars, 2) be increasing oviposition,
3) increasing mortality due to naturally occurring pathogens. The
laboratory data may help answer these questions.























INSECTICIDES ON PEPPER

D. J. Schuster

Location: Block B, Land 10

Objective: To evaluate a new insecticide with the registered standards for
control of pepper weevil on bell pepper.

Crop: Pepper, cv. Jupiter; transplanted Feb. 26, 1987.

Treatments: 1. Check (water-sprayed)
2. Baythroid 2 EC (0.0384 Ib ai)
3. Asana 1.9 EC (0.025 lb ai)
4. Pydrin 2.4 EC (0.1 lb ai)
5. Vydate 2L (1.0 lb ai)

Operation: Treatments will be applied weekly beginning at first flowering.
Excised and harvested fruit will be examined for damage caused by pepper
weevils.

Summary: All insecticidal treatments have resulted in reduced pepper
weevil damage in previous small plot experiments compared to the water
check. The relative efficacy of the insecticides has varied from season to
season.















INSECTICIDES ON TOMATO


D. J. Schuster

Location: Block B, Land 10

Objective: To evaluate chemical and microbial insecticides for control of
lepidopterous larvae and evaluate chemicals for control of leafminers on
tomato.

Crop: Tomato, cv. Sunny; transplanted Feb. 24, 1987.


Treatments:


1. Check (water)
2. Dipel 2x (0.5 lb product)
3. Dipel 2x (0.5 lb product) &
corn oil (1 qt)
4. Dipel 2x (0.5 lb product) & corn oil (1 qt)
applied twice weekly.
5. ABG 6190 (1 qt)
6. ABG 6190 (1 qt) & corn oil (1 qt)
7. ABG 6190 (1 qt) & corn oil (1 qt)
applied twice weekly.
8. Baythroid 2 EC (0.0344)
9. Baythroid 2 EC 0.0250 lb ai) &
Trigard 75 WP (0.125 lb ai)

Operation: Treatments will be applied weekly (except where noted above)
beginning 2-3 weeks after transplanting. The number of leafmines and
caterpillars will be periodically evaluated. The number of undamaged fruit
and those damaged by insects will be determined at harvest.

Summary: The microbial insecticides, Dipel and ABG 6190, may be more
efficacious when applied twice weekly or when combined with corn oil.
Baythroid, a pyrethroid, has consistently controlled caterpillars and stink
bugs but not leafminers. Trigard has consistently controlled leafminers
but not caterpillars or stink bugs. Combining Baythroid and Trigard gives
broad spectrum insect control.






















LEAFMINER RESISTANCE IN TOMATO

D. J. Schuster, J. W. Scott

Location: Block B, Lands 11 and 12

Objective: To evaluate Lycopersicon germplasm for resistance to
leafminers.

Crop: Tomato; transplanted March 3.

Selections: 'Sunny' susceptible standard
PI 126449 &
PI 134417 resistant standards
870967-90 germplasm for evaluation.

Operation: Foliage samples of each plant of each selection will be
evaluated in the laboratory for the concentration of decanone, a chemical
associated with insect resistance. Periodic evaluations of the extent of
leafmining in each plant will be compared with the chemical analyses
results. Fruit from individual plants indicating leafminer resistance will
be harvested for further cycles of selection.

Summary: PI 126449 & PI 134417 are highly resistant to leafminers;
however, these PI's are wild species of the tomato and the transfer of
resistance and horticultural characteristics is difficult. The correlation
between decanone content and leafmining has not been consistent. Combining
both lab and field evaluations, however, could assure the elimination of
pseudoresistant plants (those which are not resistant but have escaped
leafminer attack).

Operation: Plots were established on the same site as during the summer
and fall 1985 and spring 1986. Nematodes and wilt diseases were assayed in
each season since summer 1985. Tomato yields were and will be recorded.

Comments: To date, the tomato crop immediately following summer
solarization has produced tomato yields equal to fumigation. Tomato as a
re-crop in the spring has not benefitted from solarization, but did benefit
from fumigation in the fall crop. Solarization gave exceptional control of
Verticillium wilt during both seasons last year. Fusarium wilt and
nematode control were less spectacular.

CALABAZA SEED INCREASE

D. N. Maynard

Location: Block C, Land 12; Block N, Land 16

Objective: To increase seed of 'La Primera' and 'La Segunda' calabaza squash.

Crop: Squash, seeded March 10, 1987

Operation: Standard squash cultural and pest management practices are
followed. Seed will be extracted from selected, typical fruit of each cultivar.

Summary: Calabaza squash is an excellent product with potential for
increased production. 'La Primera' and 'La Segunda' are improved cultivars
introduced by Dr. Ray Volin, a former faculty member at the Tropical
Research and Education Center, Homestead. Commercial seed of these
cultivars is not available; seed produced here will be used in county
extension demonstrations to make growers aware of the potential for
calabaza production.

ICEBOX WATERMELON POSTHARVEST STUDIES


D. N. Maynard, L. A. Risse

Location: Land C, Block 13

Objective: Icebox watermelon are being grown for use in postharvest
studies.

Crop: Watermelon, cv. 'Baby Fun', 'Mickylee', 'Minilee'

Operation: Standard watermelon cultural and pest management practices are
followed. Harvested melons will be transported to the USDA postharvest
laboratory in Orlando for film wrapping and storage studies.

Summary: It is necessary to determine storage parameters and the
feasibility of film wrapping for both domestic and export marketing of
icebox watermelons to enable greater production of these melons by Florida
growers.



ICEBOX WATERMELON SPACING TRIAL

D. N. Maynard, P. R. Gilreath

Location: Block C, Land 31

Objective: To determine the effects of in-row spacing on icebox watermelon
fruit size and production.

Crop: Watermelon, cv. 'Baby Fun' and 'Minilee'; transplanted Feb. 26,
1987.

Treatments: Each cultivar is grown at 1.0, 1.5, and 2.0 ft. in-row spacing
on beds on 9 ft. centers.

Operation: Standard watermelon cultural and pest management practices are
followed. At harvest, individual fruit weight and soluble solids will be
determined.

Summary: In previous trials, 'Baby Fun' fruit size was a bit too large for
icebox size when grown at 2.0 ft. in-row spacing, whereas 'Minilee' fruit
size was judged to be about ideal. This trial is designed to determine if
fruit size of these cultivars can be controlled by in-row spacing.
Identical trials are being conducted on commercial farms in Manatee and
Collier Counties.










TOMATO BACTERIAL SPOT RESISTANCE BREEDING


J. W. Scott, J. B. Jones, G. E. Cameron

Location: Block C, Lands 15-18

Objective: To select plants with good levels of bacterial spot resistance
and horticultural type for future variety release.

Field Set: February 27, 1987

Treatment: Ninety-five BC4SI's and control lines Hawaii 7998, Campbell-28,
Sunny, Suncoast, and Horizon.

Operation: Normal pesticide practices except no mancozeb and copper
sprays. Plants were inoculated with 107 cfu/ml of Xanthomonas campestris
pv. vesicatoria, the causal organism of bacterial spot. Overhead
irrigation was then used to aid in disease infection. Plants were rated
for resistance and will then be selected for horticultural type.

Summary: It is hope that there will be some selections which combine
bacterial spot resistance and enough horticultural type to allow for
limited commercial testing as early as 1988. Selections will be re-tested
on the same plots this fall.

LEAFMINER SAMPLING ON TOMATO

T. G. Zoebisch, D. J. Schuster

Location: Block D, Lands 8, 9, 10

Objective: To develop a sampling procedure for estimating the density of
leafminer adults and predicting the subsequent larval density.

Crop: Tomato, var. 'Sunny'

Transplanted: March 4, 1987

Operation: Cages will be placed over tomato plants in the field. Yellow
sticky cards will be placed inside and outside of the cages and the numbers
of leafminer adults trapped will be counted 24 hrs later. Leafminer adults
remaining inside the cages will be killed with a pyrethum spray and removed
from the cages. Known numbers of leafminer adults will be released into
each cage. Sticky cards will once again be placed in each cage and the
numbers of leafminer adults trapped will be counted 24 hrs later. The
relationship between sticky card captures and known leafminer density will
be described mathematically. This description will then be used to
estimate the unknown leafminer densities.

Summary: Experimentation completed in the fall 1986 season indicated a
reasonable relationship between trap catches and known densities. This
relationship will be studied further this spring. In addition, the
relationship between estimated leafminer adult density and the subsequent
predicted larval density will be studied.















RESPONSE OF TOMATO TO COMMAND


J. P. Gilreath

Location: Block E, Land 6 middle of field

Objective: To determine the effect of various concentrations of Command
herbicide on tomato when applied to plant foliage (as in drift from a
treated crop) as a single application versus two applications.

Cultivar: Sunny

Treatments:

Treatment Rate No. of Stage of
No. (lb.a.i./A) applications growth

6. Command 0.01 2 1 & 2
7. Command 0.1 2 1 & 2
8. Command 1.0 2 1 & 2

Stage of growth: 1 = prebloom, 2 = 14 days after prebloom application.

Operation: Planted 2-27-87. Foliage of plants will be treated as
indicated with directed sprays. Rates range from the high end of those
likely to be encountered as drift to the rate for a direct application as
might be experienced with a contaminated sprayer. Visual evaluations of
plant injury will be made at intervals. Fruit will be harvested, sorted,
and graded.

Summary: Command has been accused in the midwest of volatilizing and
drifting onto surrounding crops, including tomatoes, from soybean fields
after application. Research in the fall of 1986 indicated no yield
reduction where Command was applied pre or postbloom at rates up to 0.1
Ib.a.i./acre. Present research is designed to 1) support these findings,
2) determine if application of 1.0 lb. has an effect on yield, and 3)
determine if multiple exposures will reduce yield.















RESPONSE OF PEPPER TO ROUNDUP
SPRING 1987

J. P. Gilreath

Location: Block E, Land 6 South

Operation: Plants were transplanted 3-2-87 into mulched beds. Plants will
be sprayed with Roundup as indicated. Visual evaluations will be made for
injury and yield data will be taken.

Summary: In spring 1986, rates as high as 0.25 lb were not injurious at
either stage of growth; however, in fall 1986, rates of 0.125 lb. or
greater reduced fruit yield.

TIME OF APPLICATION: 1st APPLICATION AT BLOOM, 2nd 10 DAYS AFTER 1st.

Operation: Planted 2-24-87 (tomato) and 2-26-87 (pepper). Plants will be
treated with directed sprays of the indicated herbicides at the specified
rates. Visual evaluations will be made for degree of injury at selected
time intervals after application. Fruit will be harvested,sorted, and
graded.

Summary: Previous research with tomato and pepper indicated that single
applications of rates of 2,4-D and dicamba (Banvel) as low as 0.0001
lb.a.i./acre produced noticeable injury to tomato foliage and pepper
foliage and fruit; however, significant yield reductions were not
encountered until the rate reached 0.01 lb.a.i./acre and higher. This
research is designed to further document this effect and to determine if a
second exposure causes any greater damage than a single application.





















WEED CONTROL IN PEPPER ROW MIDDLES

3-13-87 and posttransplant, preemergence treatments were applied 3-16-87.
Weed control will be evaluated several times during the season. Fruit will
be harvested, sorted, and graded.

Summary: Several of the herbicide treatments have been demonstrated as
being effective for morningglory control in other crops, but safety to
tomato plants is currently unknown. Blazer controls morningglories, but it
has been both phytotoxic and nonphytotoxic to tomatoes in past research.
Goal + Fusilade 2000 (tank mix) has shown promise in past research, but
data are not available for morningglory control in tomatoes.

TENSIOMETER SCHEDULED MICRO-IRRIGATED TOMATO PRODUCTION


C. D. Stanley, G. A. Clark, A. A. Csizinszky

Location: Block G, Land 1

Objective: 1) Evaluate the use of tensiometer-controlled irrigation
scheduling for micro-irrigation.

2) Evaluate the effect of maintaining different soil moisture
levels on tomato production.

Crop: Tomato, cv 'Sunny'

Treatments: Soil moisture levels 1) 10 centibars
2) 20 centibars
3) 30 centibars

Operation: All fertilizers were applied pre-plant in dry form, and placed
in an 8-inch wide band and incorporated 3 inches. Each plot within each
replication is independently controlled. Each tensiometer in each plot is
checked 2 times daily by an electronic controller for a signal that
irrigation is needed (by sensing a switch closure). Marketable fruit
production and quality will be measured. Irrigation water application and
nutrient movement in the soil will be analyzed several times during the
season.

TOMATO FUSARIUM WILT RACE 3 AND
FUSARIUM CROWN ROT RESISTANCE BREEDING

J. W. Scott

Location: Block J, Lands 11, 12

Objective: To select plants with Fusarium wilt race 3 or Fusarium crown
rot resistance and good horticultural type for future variety release.

Field Set: Feb. 25, 1987

Treatment: Two-hundred-eighteen breeding lines segregating for Fusarium
race 3 resistance and fifty-eight breeding lines segregating for Fusarium
crown rot resistance.

Operation: All plants were root dip inoculated at the colyledon stage with
respective pathogens. Survivors were planted to the field. Normal
pesticide applications were used. When fruit begin to ripen, selections
for superior horticultural type will be made.

Summary: More advanced race 3 inbreds derived from Australian resistance
sources are being selected for possible breeding line release. Most race 3
lines, at the BC4S1 stage, have been derived from a resistant source,
LA716, which confers resistance by action of a single dominant gene. Most
crown rot lines are also BC4S1's. It is hoped that selections will lead to
commercially acceptable varieties in the future.

Horizon P2
Horizon x MH-1 Fl
MH-1 x Horizon RF1
(Horizon x MH-1) BK F2
MH-1 (Horizon x MH-1) BCP1


Operation: Normal pesticide practices were used. Fruit are harvested at
the mature green stage, weighed and submerged in water under pressure for a
short time period. They are then weighed to measure water uptake.

Summary: Bacterial soft rot, incited by Erwinia sp., is one of the major
causes of postharvest decay in Florida tomatoes. Fruit are infected in
contaminated wash tanks where fruit which take up more water also take up
more bacteria. Past work has shown that Fla. MH-1 is susceptible to
Erwinia due to its high water uptake. Horizon has low water uptake and is
quite resistant. In this study we hope to see where the Fl falls and gain
some information on how to sample F2 and backcross generations. This
experiment will then be expanded in the future.



















GENOTYPE EVALUATION OF FIRMNESS AND TEXTURAL
COMPONENTS IN TOMATO

Joe Ahrens, J. W. Scott, D. J. Huber

Location: Block N, Land 9

Objective: To determine firmness of whole fruit and component parts and to
assess texture for various genotypes.

Field Set: February 17, 1987

Treatment: 3 replications, 10 plant plots

Field Designation Pedigree

E101 Rutgers
E102 Sunny
E103 Suncoast
E104 Fla 7136
E105 Fla MH-1
E106 Fla 7155
E107 Flora-Dade
E108 Angora

Operation: Normal pesticide practices were used. Fruit of each variety
were/will be harvested at the mature green stage and tested for firmness
and texture at the table ripe stage. Various means will be used to measure
firmness (Cornell pressure tester, Instron of radial and outer walls, M-T
peel puncture). Trained taste panelists will rate fruit for texture.

Summary: In this experiment we are trying to find 4 genotypes; firm and
mealy, firm and not mealy, soft and mealy, soft and not mealy. We hope
then to chemically identify some of the components of each genotype and
possibly study the inheritance of firmness and mealyness.























TOMATO FUSARIUM WILT RACE ASSOCIATION PHASE 1


Brian Bournival, J. W. Scott

Location: Block N, Land 9, 10

Objective: To determine if race 3 resistance is linked, allelic, or
assorts independently from race 2 and race 1 resistance.

Field Set: February 17, 1987; March 10, 1987, E305 set March 18, 1987

Treatment:
Field Designation Pedigree Generation

E 301s Bonny Best (Bonny Best x LA 716) BCP1
E 302s (Bonny Best x LA 716)-BK F2
E 303s Bonny Best (Bonny Best x E 427) BCP1
E 304s (Bonny Best x E 427)-BK F2
E 305s Bonny Best (Bonny Best x LA 716) BCP1

Operation: Normal pesticides were used. Selfed seed will be saved from
each of the plants. Each of these selections will then be screened
separately for resistance to Fusarium wilt race 1, race 2, and race 3 to
see if the resistances are associated or assort independently.

Summary: Race 3 resistance derived from LA 716 is conferred by a single
dominant gene as has been reported earlier for races 1 and 2. LA 716 is
also resistant to races 1 and 2. This is part of an overall study to find
the location of the race 3 gene (13) on the linkage map. This study will
provide evidence for the relationship of these resistance genes.
























DEVELOPMENT OF THE IDEAL PLANT HABIT FOR GROUND TOMATOES


J. W. Scott

Location: Block N, Land 12

Objective: To select plants with adequate fruit cover for production
without stakes.

Field Set: February 17, 1987

Treatment: Sixteen breeding lines and controls. Most breeding lines at
the BC2 Sl stage.

Operation: Normal pesticide practices were used. Plants were selected
early on for ideal plant habits. Later they will be selected for superior
horticultural type.

Summary: Work in Israel indicated plants with multiple branching and short
internodes cover plastic mulch well without blowing to one side for maximal
photosynthesis. They also cover fruit well to prevent sunburn. This work
is to see if such types can be selected for Florida. Thus an alternative
to staking the plants might be possible. Work is still in the early
phases.













BREEDING MALE-STERILE TOMATOES


J. W. Scott

Location: Block N, Land 13

Field Set: February 24, 1987

Treatment: Ninety-seven breeding lines and controls.

Operation: Male-sterile segregants are flagged and rated for stigma
exposure which will facilitate cross-pollination. Fertile plants are rated
for stigma position and horticultural type. Sib pollinations are made on
superior types.

Summary: Most commercial acreages of tomatoes in Florida are planted with
hybrid varieties. Cost of such varieties could be reduced and availability
of seed increased if male-steriles could be used as parents for these
varieties. This work is intended to develop commercially acceptable fresh
market and cherry steriles for this purpose. Emphasis is being placed on
incorporation of a seedling marker and an enzyme marker. These markers
will enable seedsmen to identify sterile and fertile plants for seed
production plots.



BREEDING PARTHENOCARPIC TOMATOES

J. W. Scott

Location: Block N, Land 14

Field Set: February 24, 1987

Treatment: Fifty-four breeding lines and controls.

Operation: Flowers of each plant are planted on a tissue culture medium
and scored for growth which indicates presence of parthenocarpy. Ripe
fruit are later cut to verify parthenocarpic expression. Selections are
made for plants with parthenocarpy and good horticultural type.

Summary: Fruit set during periods of stress to cold, heat, or rain could
theoretically be enhanced by production of parthenocarpic (seedless) fruit.
These fruit have normal gel fill but do not require fertilization which
might be a limiting step in the fruit set process under stress conditions.
Progress has been slow on this project but attempts to obtain large fruited
parthenocarpic lines is underway here.











TOMATO BACTERIAL WILT RESISTANCE BREEDING


J. W. Scott, J. B. Jones, G. E. Cameron

Location: Block N, Lands 15, 16

Field Set: Feb. 24, 1987 and Feb. 26 (extra plants)

Objective: To select plants with bacterial wilt resistance and good
horticultural type for future variety release.

Treatment: Eighty breeding lines (Most BC3SL's) plus controls.

Operation: Roots of thirty-two day old plants were cut in Speedling (size
#i50) trays and a 5 ml suspension of Pseudomonas solanacearum (108 cfu/ml)
was poured into each cut area. Plants were then transplanted in the field
at 6" spacing. Seeds from resistant plants of each line with better
horticultural type will be bulked for rescreening next season.

Summary: It is hoped that selections will have enough horticultural type
to eventually lead to acceptable commercial varieties.


RELATIONSHIP BETWEEN BACTERIAL SPOT AND
BACTERIAL WILT RESISTANCE IN TOMATO

J. W. Scott, G. E. Cameron, J. B. Jones

Location: Block J, Land 16

Field Set: March 9, 1987

Objective: To determine if there is an association between bacterial spot
resistance and bacterial wilt resistance.

Treatment: Thirty-one bacterial spot resistant breeding lines and control
lines Hawaii 7997, Hawaii 7998, Campbell-28, and Walter.

Operation: Roots of 34 day old plants were cut in Speedling (size #150)
trays and a 5 ml suspension of Pseudomonas solanacearum (108 cfu/ml),
causal agent of bacterial wilt, was poured into each cut area. Plants were
transplanted to the field and will be rated for bacterial wilt on a weekly
basis once symptoms begin to appear.

Summary: This is one of a series of experiments we are conducting to see
if there is an association of these disease resistances. We know bacterial
wilt resistance does not confer bacterial spot resistance, but it may be
that bacterial wilt resistance is needed for bacterial spot resistance to
occur. Our bacterial spot resistant source, Hawaii 7998, is a bacterial
wilt resistant accession. If there is an association, then a high
percentage of the lines selected only for bacterial spot resistance should
also be bacterial wilt resistant.




























SWEET CORN VARIETY TRIAL

T. K. Howe, W. E. Waters

Location: Block N, Land 18

Objective: To evaluate supersweet sweet corn varieties and breeding lines
in replicated trial.

Crop: Supersweet (shrunken-2 genotype) sweet corn.

Direct Seeded: April 15, 1987

Trial Entries: Field will be marked.

Operation: Ears will be hand harvested as needed for each cultivar.
Comparisons of yields, earliness, concentration of harvest and ear
characteristics will be assessed.

Summary: In progress. Harvest in early June.
