In 1994-95, 49,000 acres of tomatoes were harvested in Florida, yielding 64.2 million 25-pound
cartons worth $461 million (Fla. Agr. Stat. Serv., 1996). Tomatoes accounted for 30% of the total
production value for all vegetables grown during 1993-94, making it the most important vegetable
produced in the state. The Palmetto-Ruskin area (west-central Florida) accounted for 30% of the
state's total fresh market tomato production in 1993-94 (Fla. Agr. Stat. Serv., 1995).

A tomato variety trial was conducted in fall 1995 at the Gulf Coast Research & Education Center in
west-central Florida to evaluate fresh market tomato varieties and breeding lines. Twenty-one entries
were evaluated in a replicated yield trial and an additional 46 entries were evaluated visually in
unharvested observational plots.

MATERIALS & METHODS

Bed Preparation: The 32.5-inch wide, 8-inch high beds were spaced on 5 ft centers with 6 beds
between seepage irrigation ditches. Fertilizer included 15-0-30 (N-P20O-K20) at 1742 lb/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 the bed center. In addition, a banded false bed application was made of
superphosphate (0-20-0 with 80 lbs per ton minor elements as F503) at 174 lb/A. This fertilizer
regime provided a 1:2 ratio of N:K20 with approximately 260 lb N/A and 523 lb K20/A. Beds were
fumigated with methyl bromide:chloropicrin (67:33) at 189 lb/mulched A (mulched acre = 23,522 sq
ft) and covered with black polyethylene film.

Transplant Production: Seeds were sown on July 11 and 12, 1995 into planter flats (1.5 x 1.5 x 2.5-
inch cells) containing vermiculite and Canadian peat (l:l,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.

Crop Production: Transplants were set in the field on August 22 and spaced 24 inches apart in single
rows down the center of each bed. Transplants were immediately drenched with water containing
imidacloprid to control silverleafwhitefly populations. Fields were also baited for mole crickets after
transplanting. 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. Lepidopterous larvae, leafininers and silverleaf
whitefly were the primary insects found. Bacillus thuringiensis, permethrin, avermectin, endosulfan,
methamidophos, fenpropathrin, chlorpyrifos, cryolite, methomyl, and azadirachtin were used
according to label instructions to control insect pest populations during the season. Bacterial leaf
spot was prevalent through late October and a spray program using mancozeb, copper salts,
chlorothalonil and chlorothalonil plus copper oxychloride was followed for control of bacterial as well
as fungal-incited diseases.

Fruit of the replicated entries were harvested at the mature-green stage or beyond on November 2,
13, 27 and December 12, 1995. 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 2-4 for
specifications). Both cull and marketable fruit were counted and weighed. Subjective ratings of plant
and fruit characteristics were given to the observational entries.

RESULTS & DISCUSSION

Average maximum and minimum daily temperatures were above normal as compared to the 41-year
averages during August, September and October, but below normal during November and December
(Table 1). Rainfall was above average during all months but December. The combination of high
temperatures, high relative humidity and rainfall adversely affected early season fruit set by promoting
flower abortion due to a high incidence of bacterial leaf spot on the blossoms and pollination failure.


REPLICATED TRIAL

Seasonal: Total marketable yield among all entries from four harvests ranged from 1056 25- lb
cartons/A for 'Bonita' to 2351 cartons/A for Fla. 7514 (Table 2). 'Equinox' (2285 cartons/A), Fa.
7578 (2237), FT 4029 (2151) and 'Solar Set' (2144) yields were not significantly different from Fla.
7514. All but two entries exceeded the 1993-94 State average of 1311 cartons/A (Fla. Agr. Stat.
Serv., 1996). Yield of extra-large fruit ranged from 280 cartons/A for 'Bonita' to 1159 cartons/A for
Fla. 7514. Only three other entries were similar to Fla. 7514 in extra-large fruit yield for the season:
'Merced' (1062 cartons/A), Fla. 7578 (1053) and FT 4029 (931). Yield of large fruit ranged from
456 cartons/ A for 'Bonita' to 994 cartons/A for 'Equinox'. Only four entries were similar to
'Equinox' in yield of large-sized fruit, they were: Fla. 7514, Fla. 7578, 'Solar Set' and 'Solimar'.
Average individual fruit weight ranged from 4.8 oz for FMX 174 to 5.9 oz for 'Merced'. 'Merced'
(5.9 oz), and Fla. 7658 (5.7 oz) were not significantly different from each other in average individual











fruit weight. Cull fruit accounted for 21-38% of total harvest. Defects of culled fruit included radial
cracks, misshapen fruit, large blossom end scars, concentric cracks, zippering, rough shoulders,
holes/folds in the walls and nipple-tipped blossom ends. Radial cracking was the predominant defect
during the season.

First Harvest (November 2): Total marketable yield for the first harvest ranged from 11 cartons/A
for 'Bonita' to 395 cartons/A for Fla. 7578 (Table 3). Only Fla. 7658 and Fla. 7514 were similar to
Fla. 7578 in early total marketable yield. Extra-large fruit yield ranged from 6 cartons/A for 'Bonita'
to 350 cartons/A for Fla. 7578. Only Fla. 7658 (323 cartons/A), Fla. 7514 (295) and 'Merced' (235)
were similar to Fla. 7578 in extra-large fruit yield. Although these first-harvest yields were very low,
the harvest highlights individual entries which had better yields under stressful weather conditions.
Yields at this harvest for all entries in the large fruit grade were under 50 cartons/A, and under 7
cartons/A in the medium fruit grade. Average individual fruit weight ranged from 5.7 oz for 'Bonita'
to 8.0 oz for 'Merced' and 'Agriset 761'. Sixteen other entries were similar to 'Merced' and 'Agriset
761' in average fruit weight at the first harvest. Cull fruit accounted for 25-76% of the total fruit
harvested at the first pick. The predominant defects of cull fruit were radial cracks, misshapen fruit
(flattened, holes/folds in wall), rough shoulders and nippled blossom ends, in decreasing order.

Second Harvest (November 13): The total marketable yield for the second harvest ranged from 42
cartons/A for 'Bonita' to 538 cartons/A for Fla. 7578 (Table 4). Eight entries were similar to Fla.
7578 in yield. Extra-large fruit yield ranged from 11 cartons/A for 'Bonita' to 327 cartons/A for Fla.
7514. Seven other entries were not significantly different from Fla. 7514 in yield of extra-large fruit
at the second harvest. Large fruit yields ranged from 27 cartons/A for 'Bonita' to 226 cartons/A for
Fla. 7578. Average individual fruit weight ranged from 5.0 oz for Sunre 6620 to 6.0 oz for 'Merced'.
Only two entries, FMX 174 and Sunre 6620, were significantly different than 'Merced' in fruit weight
at the second harvest. Cull fruit accounted for between 28 and 62% of the total harvest.

Third Harvest (November 27): Marketable yield at the third harvest ranged from 289 cartons/A for
FMX 174 to 809 cartons/A for 'Solar Set' (Table 5). Fifteen entries yielded as well as 'Solar Set'
at this harvest. Extra-large fruit yields ranged from 47 cartons/A for FMX 174 to 367 cartons/A for
'Merced'. Only two entries yielded as well as 'Merced' in the extra-large fruit category at this
harvest, Fla. 7514 and 'Solar Set'. Most of the fruit harvested was size graded as large, only
'Merced' produced more extra-large than large fruit at the third pick. Large fruit yields ranged from
136 cartons/A for FMX 174 to 365 cartons/A for 'Agriset 761'. Average marketable fruit size
ranged from 4.7 oz for FMX 174 to 5.7 oz for 'Merced'. 'Merced' produced the largest fruit size
at this time. Cull fruit accounted for 13 to 36% of the harvest.

Fourth Harvest (December 12): Marketable yield at the fourth and final harvest ranged from 403
cartons/A for Fla. 7658 to 927 cartons/A for FT 4029 (Table 6). This harvest produced the greatest
total yields of the season for 14 of the 21 entries. However, the fruit size was predominantly in the
large category. Extra-large fruit yields ranged from 136 cartons/A for Fla. 7658 to 272 cartons/A
for NC 94190. Large fruit yields ranged from 160 cartons/A for Fla. 7658 to 382 cartons/A for NC
94190 and 'Equinox'. Few significant differences were found among the varieties at this harvest with











respect to yield. Average fruit weight ranged from 4.5 oz for 'Sunny' to 5.3 oz for 'Merced'. Cull
fruit accounted for 18 32 % of the harvest.

UNHARVESTED OBSERVATIONAL TRIAL

Horticultural Evaluation: All observational entries were rated for numerous horticultural
characteristics (Table 7). Maturity and fruit size were rated on November 20-21. Other plant and
fruit attributes were rated on December 13-15 when most fruit were ripe. Ratings provide general
indications of crop performance at a particular location and time.

SUMMARY

Extra-large fruit yield is one of the most important aspects of marketing Florida tomatoes, since this
size fruit generally secures a premium price. Additionally, earliness can be a key to profitability if one
grower brings fruit to market ahead of competitors. Adverse weather conditions during the fall 1995
production season dramatically reduced early extra-large fruit set and effectively prolonged the
harvest season. To illustrate, in a fall trial conducted in 1994, early extra-large fruit yields ranged
from 58 to 515 cartons/A with an average among the entries of 313 cartons/A (Howe, et. al., 1995a).
This is contrasted to the yields in the fall of 1995 which ranged from 6 to 350 cartons/A with an
average of 163 cartons/A among the entries. There was nearly a 50% reduction in early extra-large
fruit yield in the fall of 1995 compared to 1994. Total seasonal yields between the two fall seasons
appear very similar, although there was an additional harvest in the fall of 1995.

However stressful the fall of 1995, several entries stood out: Fla. 7578, Fla. 7658, Fla. 7514, and
'Merced' were not significantly different in providing the highest extra large fruit yields at the first
harvest. Fla. 7578 is a heat tolerant hybrid, Fla. 7658 is Fusarium race 3 resistant and heat tolerant,
and Fla. 7514 is bacterial wilt tolerant and heat tolerant. Fla 7578 and Fla. 7514 have done well in
previous spring and fall trials (Howe, et. al., 1995a, 1995b). 'Merced' has not been promoted as heat
tolerant, even though it has been consistently high yielding in fall trials at this location and has
performed as well as heat tolerant tomatoes (Howe et al., 1992a, 1993a, 1994a, 1995a).

Fla. 7514, 'Equinox', Fla. 7578, FT 4029 and 'Solar Set' provided the good total yields for the
season. While seasonal extra large fruit yield was good for Fla. 7514, Fla. 7578 and FT 4029.
'Equinox', a recently released heat-tolerant hybrid tested as Fla. 7249B (Scott et. al., 1995), has been
a proven performer in previous spring and fall trials (Howe, et.al., 1992a, 1992b, 1993a, 1993b,
1994a, 1994b, 1995a, 1995b).

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-
