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 31% of the
state's total fresh market tomato production in 1994-95.
A tomato variety trial was conducted in fall 1996 at the Gulf Coast Research & Education Center
in west-central Florida to evaluate fresh market tomato varieties and breeding lines. Twenty-two
entries were evaluated in a replicated yield trial and an additional 62 entries were evaluated visually
in unharvested observational plots.
MATERIALS & METHODS
Soil Test Results: Soil in the trial area was sampled before field preparation and analyzed by the
IFAS Soil Testing Lab. The pH = 6.5, NH4-N = 3.2 ppm and NO3-N = 4.8 ppm were determined
from a water extract (Geraldson, 1967), and P = 73 ppm, K = 30 ppm, Ca = 757 ppm, and Mg = 109
ppm were determined from a Mehlich I extract (Hanson and DeVore, 1989).
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-P205-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 Ibs per ton minor elements as F503) at 174 Ib/A. This fertilizer
regime provided a 1:2 ratio of N:K0 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 white on black polyethylene film.
Transplant Production: Seeds were sown on July 15, 1996 into planter flats (1.5 x 1.5 x 2.5-inch
cells) containing vermiculite and Canadian peat (1: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.

16 Crop Production: Transplants were set in the field on August 26 and spaced 24 inches apart in single
r C / rows down the center of each bed. Transplants were immediately drenched with water containing
imidacloprid for silverleaf whitefly control. Fields were also baited for mole crickets after
( CS transplanting. Four replications of 10 plants per entry were arranged in a randomized complete block
S, design in the replicated trial and single 10-plant plots were used in the observational trial. Plants
were staked and tied without pruning.
LIBRARY Plants were scouted for pests throughout the season. Lepidopterous larvae, leafminers and silverleaf
whitefly were the primary insects found. Bacillus thuringiensis, insecticidal soap, esfenvalerate,
avermectin, endosulfan, methamidophos, fenpropathrin, cryolite, and methomyl were used according
to label instructions to control insect pest populations during the season. A preventative spray
program using maneb, copper salts, chlorothalonil and chlorothalonil plus copper oxychloride was
followed for control of bacterially as well as fungally-incited diseases. Disease pressure was
minimal during the season due to lower than normal precipitation.
Fruit of the replicated entries were harvested at the mature-green stage or beyond on November 12,
21, and December 5, 1996. 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 daily temperatures were normal or slightly above normal compared to the 42-year
averages during the entire season (Table 1). Average minimum daily temperatures were normal or
within two degrees of normal during the season. Rainfall was well below average during August,
September and November, slightly below average during December and higher than the average
during October. The sparsity of rainfall probably contributed to reduced disease pressure and fruit
disorders.
REPLICATED TRIAL
Seasonal: Total marketable yield among all entries from three harvests ranged from 2306 25-1b
cartons/A for ACX 12 XL to 2981 cartons/A for XPH 10047 (Table 2). Sixteen other entries were
not significantly different than XPH 10047 in total seasonal yields. All entries greatly exceeded the
1994-95 State average of 1311 cartons/A (Fla. Agr. Stat. Serv., 1996). Yields were also much higher
than seen in previous fall trials at this location (Howe et. al. 1996, 1995a, 1994a, 1993a, 1992a).
Yield of extra-large fruit ranged from 781 cartons/A for 'Leading Lady' to 1805 cartons/A for XPH
10047. Only seven other entries were similar to XPH 10047 in extra-large fruit yield for the season:
'Affirm' (1713 cartons/A), XPH 10035 (1630), 'Merced' (1624), 'Agriset 761' (1488), Fla. 7658
(1478), 'Equinox' (1468), and FT 4029 (1454). Yield of large fruit ranged from 548 cartons/A for
'Affirm' to 1169 cartons/A for 'Leading Lady'. Eleven entries were similar to 'Leading Lady' in
yield of large-sized fruit. Average individual fruit weight ranged from 5.0 oz for Fla. 7578 and
'Leading Lady' to 6.2 oz for 'Affirm'. 'Affirm' had significantly greater fruit weight than all other
entries for the season. Cull fruit varied from 13-30% for the various entries. Misshapen fruit and
fruit with rough shoulders were the predominant defects during the season. Other defects of culled
fruit included large blossom end scars, radial cracks, concentric cracks, zippering, holes/folds in the
walls, and nipple-tipped blossom ends.
First Harvest (November 12): Total marketable yield for the first harvest ranged from 160 cartons/A
for 'Bonita' to 798 cartons/A for 'Merced' (Table 3). Seven other entries were similar to 'Merced'
in total early yield, Fla. 7658 (718 cartons/A), Fla. 7578 (684), 'Spica' (670), 'Equinox' (581), FT
4029 (566), ACX 12 XL (560) and Fla. 7514 (528). Extra-large fruit yield ranged from 124
cartons/A for 'Bonita' to 675 cartons/A for 'Merced'. Six other entries were similar to 'Merced' in
early extra-large marketable yield, Fla. 7658 (588 cartons/A), 'Spica' (540), 'Equinox' (501), FT
4029 (498), Fla. 7578 (483), and XPH 10047 (450). Yields at the first harvest for all entries in the
large fruit grade were under 160 cartons/A, and under 45 cartons/A in the medium fruit grade.
Average individual fruit weight ranged from 5.9 oz for 'Leading Lady' to 8.8 oz for 'Affirm'.
'Affirm' had significantly larger individual fruit weight than all other entries at the first. Cull fruit
varied from 15 to 52% of the total fruit harvested for the entries. The predominant defects of cull
fruit were radial cracks, misshapen fruit (flattened, holes/folds in wall), and rough shoulders, in
decreasing order. Radial cracking was a particular problem for only certain cultigens.
Second Harvest (November 21): The total marketable yield for the second harvest ranged from 615
cartons/A for 'Sanibel' to 1191 cartons/A for XPH 10047 (Table 4). Sixteen entries were similar
to XPH 10047 in total yield. Extra-large fruit yield ranged from 266 cartons/A for 'Leading Lady'
to 780 cartons/A for XPH 10047. Six other entries were not significantly different from XPH 10047
in yield of extra-large fruit at the second harvest. They were 'Affirm' (754 cartons/A), XPH 10035
(643), 'Merced' (601), FT 4029 (567), FT 3256 (535), and 'Sun Leaper'(524). Large fruit yields
ranged from 228 cartons/A for XPH 10035 to 429 cartons/A for 'Sun Leaper'. Average individual
fruit weight ranged from 5.0 oz for 'Leading Lady' to 6.4 oz for 'Affirm'. Again, 'Affirm' had
significantly higher individual fruit weight than all other entries. Cull fruit varied from 11 to 23%
of the total harvest for the entries. Fruit defects at this harvest included rough shoulders, poor fruit
shape, radial cracks, nipple-tipped blossom ends, and blossom end roughness. Radial cracking was
a particular problem in only certain entries.
Third Harvest (December 5): Marketable yield at the third harvest ranged from 794 cartons/A for
'Merced' to 1649 cartons/A for 'Agriset 761' (Table 5). Twelve entries yielded as well as 'Agriset
761'. Extra-large fruit yields ranged from 268 cartons/A for ACX 12 XL to 646 cartons/A for
'Agriset 761'. Fifteen entries yielded as well as 'Agriset 761' in the extra-large fruit category.
Seventeen of the 22 entries produced higher yields of large fruit than extra-large. Large fruit yields
ranged from 284 cartons/A for 'Affirm' to 698 cartons/A for Fla. 7514. Average marketable fruit
size ranged from 4.3 oz for Fla. 7578 to 5.5 oz for 'Affirm'. 'Affirm' produced the largest fruit size
but four entries were similar this time. Cull fruit varied from 14 to 31% of the harvest for the entries.
Rain checking, rough or misshapen fruit, zippering, cracking, and blossom end roughness were
noted as defects with rain checking and misshapen fruit predominating.
UNHARVESTED OBSERVATIONAL TRIAL
Horticultural Evaluation: All observational entries were rated for numerous horticultural
characteristics (Table 6). Plant and fruit attributes were rated on December 18-19. Ratings provide
general indications of crop performance at a particular location and time.
SUMMARY
Overall, this season's yields were excellent based on previous fall yields obtained at Bradenton
(Howe et. al. 1992a, 1993a, 1994a, 1995a, 1996). Total seasonal yields ranged from over 2300
cartons/A to just under 3000 cartons/A, while seasonal yields of extra-large fruit ranged from nearly
800 cartons/A to over 1800 cartons/A. The lack of fruit defects, particularly at the second and third
harvests, kept cull fruit yields as low as 13% for the season, with the average among all entries of
22%.
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. This season's extra-large fruit yield from
the first harvest ranged from 124 to 675 cartons/A with an average of 388 cartons/A among all of
the entries in trial. 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, and in the fall of 1994 where 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, 1996).
Several entries stood out at the first harvest: 'Merced', Fla. 7658, Fla. 7578, and 'Spica', 'Equinox',
FT 4029, and XPH 10047 were not significantly different in providing the highest extra large fruit
yields. Fla. 7658 is Fusarium race 3 resistant and heat tolerant while Fla. 7578 is a heat tolerant
hybrid. Fla 7578 has 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). '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). XPH 10047 is also a heat-tolerant hybrid which
has not previously been in a harvested trial, but has showed good characteristics in unharvested fall
trials (Howe, et. al. 1995, 1996).

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 of disciplines
represented by faculty and (8) directing graduate
student training and teaching special undergraduate
classes.
