In 1997-98, 40,400 acres of tomatoes were harvested in Florida, yielding 55.2 million 25-pound
cartons worth over $473 million (Witzig and Pugh, 1999). Tomatoes accounted for almost 30% of
the total value for all vegetables grown during 1997-98, making it the most important vegetable
produced in the state. The Palmetto-Ruskin area (west-central Florida) accounted for 33% of the
state's total fresh market tomato production in 1997-98 (Witzig and Pugh, 1999).

A tomato variety trial was conducted in spring 1999 at the Gulf Coast Research & Education Center-
Bradenton in west-central Florida to evaluate fresh market tomato varieties and breeding lines.
Twenty-seven entries were evaluated in a replicated yield trial and an additional 66 entries including
59 standard fresh market tomato entries, 6 plum tomato entries and 1 cherry tomato variety were
evaluated visually in unharvested observational plots,

Materials and Methods

Seeds were sown on 12 January into planter flats (1.5 x 1.5 x 2.5-inch cells) containing vermiculite
and Canadian peat (1:1, v:v) amended with dolomite, superphosphate, and hydrated lime (11.3, 5.6
and 2.8 lb/cu yd, respectively), then covered with a layer of coarse vermiculite and germinated in a
greenhouse. Plants were hardened before transplanting by limiting water and nutrients in the final
phase of production.

Soil samples from the experimental area obtained before fertilization were analyzed by the
University of Florida Extension Soil Testing Laboratory (Hanlon and DeVore, 1989): pH = 7.1 and
Mehlich I extractable P = 58 (high), K = 18 (very low), Mg = 101 (high), Ca = 674 (adequate), Zn
= 4.6 (adequate), Cu = 4.4 (adequate), and Mn = 3.7 (adequate) ppm. The EauGallie fine sand was
prepared in early February by incorporation of 0-0.8-0 lb. N-PO,-K,0 per 100 linear bed feet (lbf).
Beds were formed and fumigated with methylbromide: chloropicrin, 67:33 at 2.3 lb/100 lbf. Banded
fertilizer was applied in shallow grooves on the bed shoulders at 2.34-0-3.25 Ib N-P205-K,0/100 Ibf
after the beds were pressed and before the black polyethylene mulch was applied. The total fertilizer
applied was equivalent to 203-70-283 Ib N-P,05-K,0/A. The final beds were 32 in. wide and 8 in.

high, and were spaced on 5 ft centers with six beds between seepage irrigation/drainage ditches
which were on 41 ft centers.

Transplants were set in the field on 23 February and spaced 18 in. apart in single rows down the
center of each bed. Transplants were immediately drenched with water containing imidacloprid for
silverleaf whitefly control.- Four replications of 10 plants per entry were arranged in a randomized
complete block design in the replicated trial and single 10-plant plots were used in the observational
trial. Plants were staked and tied without pruning.

Plants were scouted for pests throughout the season. Silverleaf whitefly, lepidopterous larvae, and
leafminers were the primary insects found. Bacillus thuringiensis abamectin, methomyl,
fenpropathrin, endosulfan, esfenvalerate, and paraffinic oil were used according to label instructions
to control insect pest populations during the season. A preventative spray program using
azoxystrobin and chlorothalonil was followed for control of plant pathogens. Tomato yellow leaf
curl virus affected plants were removed and disposed of early in the season.

Fruit of the replicated entries were harvested at or beyond the mature-green stage on 20 May and 2
June. Tomatoes were graded as cull or marketable by U.S. standards for grades (USDA, 1981) and
marketable fruit were sized by machine (see footnotes Tables 2,3 for specifications). Both cull and
marketable fruit were counted and weighed. Subjective ratings of plant and fruit characteristics were
made on the observational entries.

Results and Discussion

In spring 1999, average daily temperatures were near normal compared to the 44-year means (Table
1). Rainfall was considerably less than normal for the entire period.

Replicated Trial

Seasonal: Total marketable yield from two harvests ranged from 1778 25-pound cartons/acre for
ACR 8608 to 2878 cartons/acre for EX 10069 (Table 2). Fifteen other entries had yields similar to
those of EX 10069. All entries produced yields well above the state average of 1525 cartons/acre
for spring 1997-98 (Witzig and Pugh, 1999). Total yields in spring 1999 were similar to those
obtained in each of the previous five spring seasons at this location (Howe et al., 1994, 1995, 1996,
1997,1998).

Yields of extra large fruit varied from 1176 cartons/acre for Fla. 7859 to 2303 cartons/acre for BHN
399. Twelve other entries had extra large fruit yields similar to those of BHN 399. Large fruit yields
ranged from 257 cartons/acre for ASX 202 to 696 cartons/acre for Fla. 7862. Eight other entries had
large fruit yields similar to those of Fla. 7862. Average fruit weight ranged from 5.3 ounces for Fla.
7859 to 7.0 ounces for BHN 399. Fifteen other entries had average fruit weight similar to BHN 399.
Cull fruit by weight varied from 12% for EX 10089 and 'Floralina' to 31% for ACR 8608. The
predominant defects were large blossom-end scars, rough shoulders, and persistent green shoulders.











Early Harvest: Early yield ranged from 706 25-pound cartons/acre for RFT 6148 to 1801
cartons/acre for 'BHN 399' (Table 3). Fourteen other entries had yields similar to those for 'BHN
399', but only two entries had yields similar to RFT 6148. Extra-large fruit yield varied from 626
cartons/acre for Fla. 7859 to 1710 cartons/acre for 'BHN 399'. Only two other entries, EX 10069
and Fla. 7851 were similar to 'BHN 399' in early extra-large fruit production. Early harvest large
fruit yield ranged from 42 cartons/acre for RFT 6148 to 201 cartons/acre for Fla. 7862. Average fruit
weight varied from 5.4 ounces for Fla. 7859 to 7.9 ounces for 'BHN 399'. Thirteen other entries had
fruit weight of 7.0 ounces or greater at the early harvest. Cull fruit varied from 10 to 27% by
weight. The principal defects were rough shoulders, large blossom scars, and persistent green
shoulders. Plant stand, obtained before harvest ranged from 80 to 100%. Most plant loss was
attributable to removing plants with obvious symptoms of tomato yellow leaf curl virus.
Performance at the second harvest is shown in Table 4.

Observational Trial: Entries in the observational trial were rated late in the season for several
horticultural characteristics (Table 5). Ratings provide an indication of general crop performance
at a particular time and location.

Summary

Overall, seasonal total yields were similar to those obtained here in the past several spring seasons
(Howe et al., 1994, 1995, 1996, 1997, 1998). In spring 1999, total yields ranged from 1778 25-
pound cartons/acre to 2878 cartons/acre.

The proportion of extra-large fruit ranged from 52% to over 75% for the entire season. The
proportion of extra-large fruit at the early harvest was even greater with outstanding performance
by 'BHN 399', EX 10069, and Fla. 7851.

The Gulf Coast Research and Education Center


The Gulf Coast Research and Education Center is
a unit of the Institute of Food and Agricultural Sci-
ences, University of Florida. The Research Center
originated in the fall of 1925 as the Tomato
Disease Laboratory with the primary objective of
developing control procedures for an epidemic out-
break of nailhead spot of tomato. Research was ex-
panded in subsequent years to include study of sev-
eral other tomato diseases.

In 1937, new research facilities were established
in the town of Manatee, and the Center scope was
enlarged to include horticultural, entomological, and
soil science studies of several vegetable crops. The
ornamental program was a natural addition to the
Center's responsibilities because of the emerging in-
dustry in the area in the early 1940's.

The Center's current location was established in
1965 where a comprehensive research and extension
program on vegetable crops and ornamental plants is
conducted. Three state extension specialists posi-
tions, 16 state research scientists, and two grant
supported scientists from various disciplines of
training participate in all phases of vegetable and
ornamental horticultural programs. This interdisci-
plinary team approach, combining several research
disciplines and a wide range of industry and faculty
contacts, often is more productive than could be ac-
complished 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 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 appropri-
ate liaison appointments, and other research centers
in extension, educational training, and cooperative
research programs for the benefit of Florida's pro-
ducers, students, and citizens.

Program areas of emphasis include: (1) genetics,
breeding, and variety development and evaluation;
(2) biological, chemical, and mechanical pest manage-
ment in entomology, plant pathology, nematology,
bacteriology, virology, and weed science; (3) produc-
tion efficiency, culture, management, and counteract-
ing environmental stress; (4) water management and
natural resource protection; (5) post-harvest physiol-
ogy, harvesting, handling and food quality of horti-
cultural crops; (6) technical support and assistance to
the Florida Cooperative Extension Service; and (7)
advancement of fundamental knowledge of disciplines
represented by faculty and (8) directing graduate
student training and teaching special undergraduate
classes.
