TOMATO VARIETY TRIAL RESULTS FOR FALL 1993

T.K. Howe, J.W. Scott and W.E. Waters'

The value of fresh market tomatoes in Florida for 1992-93 was $626 million (1).
Production of 71.8 million 25-pound cartons came from 48,400 acres. This was a
15% decrease in value and a 6% decrease in harvested acreage from the previous
year (2). In 1991-92 tomatoes had the greatest crop value, accounting for 42%
of Florida's vegetable shipping point value (2). (Figures are not yet available
for the 1993-94 season.) At that time the Palmetto-Ruskin area of west-central
Florida accounted for 28% of the state's total fresh market tomato production
with 22.4 million 25-pound cartons.

A tomato variety trial was conducted in the fall of 1993 at the GCREC in west-
central Florida to evaluate fresh market tomato varieties and breeding lines.
Twenty-three entries were evaluated in a replicated yield trial and 56 entries
were evaluated in unharvested, observational plots.

MATERIALS & METHODS

Bed Preparation: The 33-inch wide, 8-inch high beds were spaced on 5 ft centers
with 6 beds between seepage irrigation ditches. Fertilizer included 15-0-30-2
(N-P205-K20-MgO) at 1742 Ib/A (A = 8712 linear ft of bed) distributed in 2 narrow
bands in shallow grooves on the bed surface 10 inches to either side of bed
center. In addition, a banded false bed application was made of superphosphate
(0-20-0 with 80 Ibs per ton minor elements as F503) at 436 Ib/A. This fertilizer
regime provided a 1:2 ratio of N:K20 with approximately 260 lb N/A and 523 lb
K,0/A. Beds were fumigated with methyl bromide:chloropicrin (67:33) at 189
Ib/mulched A (mulched acre = 23,522 sq ft) and covered with white on black
polyethylene.

Transplant Production: Seeds were sown on 12 July into wooden flats containing
an inert processed product of spent coal and lightly covered with coarse
vermiculite. Seedlings were transferred 9 days later 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 Ib/cu yd,
respectively). Plants were conditioned before transplanting by limiting water
and nutrients in the final phase of production.

Crop Production: Transplants were set in the field on 19 August spaced 24 inches
apart in single rows down the center of each bed and immediately drenched with

respectively.








water. 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.

Plots were scouted for pests throughout the season. Sweetpotato whitefly,
lepidoterous larvae and serpentine leafminer were the primary insects found.
Bacillus thuringiensis, permethrin, esfenvalerate, insecticidal soap, avermectin,
endosulfan, oxamyl and methomyl were used according to label instructions to
manage insect pest populations during the season. A spray program using
mancozeb, tribasic copper and chlorothalonil was followed for control of
bacterial spot, early blight and other foliar diseases.

Fruit of the replicated entries were harvested at the mature-green stage or
beyond on 4, 15, and 23 November. Tomatoes were graded as cull or marketable by
U.S. standards for grades (6) and marketable fruits were sized by machine as
undersize, medium, large or extra-large (see footnotes Tables 2-4 for
specifications). Both cull and sized fruits were counted and weighed.
Subjective ratings for various categories defining plant and fruit
characteristics were given to the observational entries at the end of the season
when red ripe fruit were present on the vine.

RESULTS & DISCUSSION

Weather information for the season compared to the 39-year averages (5) is in
Table 1. Maximum and minimum daily temperatures, on average, were one to three
degrees above normal compared to the 39-year averages. Rainfall was below
average during August (-2.48 inches), September (-4.08) and November (-1.32), but
above average during October (+4.28).

Seasonal: Total marketable yields for the three harvests ranged from 701
cartons/A for 'Bonita' to 1513 cartons/A for 'Agriset 761' (Table 2). All
entries except 'Bonita', HMX 2822, Sunex 6589, 'Mountain Fresh', IFAS 7573, NVH
4471 and IFAS 7571 were not significantly different from 'Agriset 761'. Symptoms
similar to tomato mottle virus (ToMo), although unidentified as such, were
present in the field early in the season and reduced plant and fruit size. In
an attempt to quantify the effects of the virus on the crop, an appearance rating
was assigned for each plant in trial. This virus rating showed that all entries
developed some viral symptoms. The yields documented in this report are similar
to those found in the fall of 1991, another season for which virus infestation
was the predominant crop production problem (3). More typical yields for a fall
season, unaffected by virus, can be found in the fall 1992 trial report (4).
Seasonal yields of extra-large fruit ranged from 51 cartons/A for 'Bonita' to 558
cartons/A for 'Passion' and XPH 10005. Seven other entries were similar to
'Passion' and XPH 10005 in seasonal extra-large fruit yield; they were: 'Solar
Set' (475 cartons/A), 'Agriset 761' (450), FMX 174 (399), 'Merced' (386), HMX
2822 (382), 'Acclaim' (380) and 'Sunmaster' (368). Average individual fruit
weight ranged from 4.1 oz for 'Bonita' to 5.6 oz for 'Passion'. HMX 2822 (5.5
oz), XPH 10005 (5.4 oz), 'Mountain Fresh' (5.2 oz) were not significantly
different than 'Passion' in average seasonal fruit weight. Cull fruit accounted
for 18-45% of total harvest, and eleven entries had less than 30% cull fruit.

First Harvest (4 November): Total marketable yields for the first harvest ranged
from 132 cartons/A for 'Bonita' to 680 cartons/A for XPH 10005 (Table 3). Nine
other entries were not significantly different than XPH 10005 in total marketable
yield at first pick. Marketable yields for extra-large fruit ranged from 33









cartons/A for 'Bonita' to 430 cartons/A for XPH 10005. Extra-large fruit yields
for 'Passion' (385 cartons/A), 'Agriset 761' (350) and 'Solar Set' (321) were not
significantly different than XPH 10005. Average individual fruit weight ranged
from 5.1 oz for 'Bonita' to 6.7 oz for 'Mountain Fresh' and HMX 2822. Cull fruit
accounted for 22-51% of the total fruit harvested at the first pick. The defects
of cull fruit were predominately open blossom ends, zippering and radial cracking
in descending order of frequency. XPH 10005 was notable at the first harvest for
smoothness and lack of defects.

Second Harvest (15 November): The total marketable yields for the second harvest
ranged from 248 cartons/A for 'Bonita' to 487 cartons/A for 'Sunmaster' (Table
4). Only Sunex 6589, IFAS 7573, 'Merced', IFAS 7571, HMX 2822 and 'Bonita' were
significantly lower in yield from 'Sunmaster'. Extra-large fruit yields ranged
from 13 cartons/A for 'Bonita' to 118 cartons/A for 'Passion'. Ten entries were
not significantly different than 'Passion' in extra-large fruit yield at the
second pick. Generally, more fruit were in the large and medium size categories
at this harvest than in the first or last harvests. Average individual fruit
weight ranged from 4.29 oz for 'Bonita' to 5.5 oz for 'Mountain Fresh'. Seven
entries were similar to 'Mountain Fresh' in average fruit weight at the second
harvest. Cull fruit accounted for between 15 and 47% of the second harvest.

Third Harvest (23 November): Marketable yields from the third harvest ranged
from 260 cartons/A for 'Heatwave' to 588 cartons/A for HMX 2823 (Table 5). Eight
other entries were not significantly different in yield from HMX 2823. Extra-
large fruit yields ranged from 3 cartons/A for 'Heatwave' and IFAS 7573 to 85
cartons/A for HMX 2822. 'Solar Set', 'Passion', IFAS 7571, PSR 810790, and
'Mountain Fresh' were not significantly different from HMX 2822 in extra-large
fruit yield at the third harvest. Average marketable fruit weight ranged from
3.7 oz for NVH 4471 and 'Heatwave' to 4.9 oz for HMX 2822. Cull fruit accounted
for between 16 and 38% of the third harvest.

Horticultural Evaluation: All observational entries were given ratings for
numerous horticultural characteristics when most fruit were red ripe (Table 6).
Ratings provide general indications of crop performance at a particular location
and time.
SUMMARY

Overall seasonal yields were reduced by viral infection in the production area.
Seasonal extra-large fruit yield was noteworthy for XPH 10005, 'Passion', 'Solar
Set', 'Agriset 761', FMX 174, 'Merced', HMX 2822, 'Acclaim' and 'Sunmaster'.
First harvest extra-large fruit yield was exceptional for XPH 10005, 'Passion',
'Agriset 761' and 'Solar Set'.

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 offundamental knowledge ofdisciplines
represented by faculty and (8) directing graduate
student training and teaching special undergraduate
classes.
