In 1995-96, 45,500 acres of tomatoes were harvested in Florida, yielding 55.3 million 25-pound
cartons worth $440 million (Fla. Agr. Stat. Serv., 1997). Tomatoes accounted for a third of the total
production value for all vegetables grown during 1995-96, making it the most important vegetable
produced in the state. The Palmetto-Ruskin area (west-central Florida) accounted for 35% of the
state's total fresh market tomato production in 1995-96.

A tomato variety trial was conducted in spring 1997 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 44 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 = 6.4, NH4-N = 4 ppm and NO3-N = 7 ppm were determined from
a water extract (Geraldson, 1967), and P = 51 ppm, K = 31 ppm, Ca = 1055 ppm, and Mg = 166 ppm
were determined from a Mehlich I extract (Hanlon and DeVore, 1989).

Bed Preparation: The 33-inch wide, 8-inch high beds were spaced on 5 ft centers with six 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 two narrow bands in shallow grooves on the bed surface 10
inches to either side of the bed center. 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 January 10, 1997 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 February 24 and spaced 24 inches apart in
single 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 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, thrips, leafminers and
silverleafwhitefly were the primary insects found. Bacillus thuringiensis, azadirachtin, methomyl,
abamectin, endosulfan, methamidophos, fenpropathrin, cryolite, and permethrin were used according
to label instructions to control insect pest populations during the season. A preventative spray
program using maneb, copper salts, chlorothalonil, elemental sulfur, and chlorothalonil plus
metalaxyl was followed for control of bacterial and fungal diseases. Disease pressure was high
during the season due to higher than normal precipitation during April. Bacterial leaf spot, powdery
mildew, and late blight were all in evidence, with bacterial leaf spot being the most problematic.

Fruit of the replicated entries were harvested at or beyond the mature-green stage on May 15 and 27,
1997. 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

In the spring, average maximum daily temperatures were six degrees above normal during February
and March, but one degree lower than normal in April and normal in May (Table 1). Average
minimum daily temperatures were also higher than normal in February and March, while near or at
normal in April and May. Rainfall was slightly below average in February, and above normal the
remainder of the season. Particularly unusual was the record- breaking rainfall in April, which was
nearly seven inches above the 42-year average.

REPLICATED TRIAL j

Seasonal: Total marketable yield among all entries from two harvests ranged from 1828 25-lb
cartons/A for 'Agriset 761' to 2808 cartons/A for 'Equinox' (Table 2). Twelve other entries were
not significantly different from 'Equinox' in total seasonal yields. All entries greatly exceeded the
1995-96 State average of 1216 cartons/A (Fla. Agr. Stat. Serv., 1997). Total yields were equivalent
or slightly lower than obtained in four of the five most recent spring trials at this location (Howe et.
al. 1992, 1993, 1994, 1995, 1996). Yield of extra-large fruit ranged from 1218 cartons/A for
'Agriset 761' to 2183 cartons/A for 'Affirm'. No other entries were similar to 'Affirm' in extra-
large fruit yield for the season. Extra-large fruit yields were above average based on the last five
spring seasons. Yield of large fruit ranged from 277 cartons/A for 'Affirm' to 905 cartons/A for Fla.
7699. Only 'Flavor More 223' (812 cartons/A) and 'Sun Leaper' (750 cartons/A) were similar to
Fla. 7699 in yield of large-sized fruit. Average individual fruit weight ranged from 5.3 oz for 'Flavor
More 223' and Fla. 7699 to 7.2 oz for 'Affirm'. 'Affirm' had significantly greater fruit weight than











all other entries, except 'Merced' (6.8 oz). Cull fruit varied from 20-41% of total harvest for the
various entries. Poor blossom end scars and fruit with rough shoulders were the predominant defects
during the season. Other defects of culled fruit included, lepidopterous larvae feeding damage,
zippering, radial cracks, concentric cracks, irregular shape, holes/folds in the walls, nipple-tipped
blossom ends, and rain check.

First Harvest (May 15): Total marketable yield for the first harvest ranged from 648 cartons/A for
'Agriset 761' to 1627 cartons/A for 'Affirm' (Table 3). Only 'Merced' at 1388 cartons/A was
similar to 'Affirm' in total early yield. Extra-large fruit yield ranged from 527 cartons/A for 'Agriset
761' to 1524 cartons/A for 'Affirm'. No other entries were similar to 'Affirm' in early extra-large
marketable yield. Large fruit yields at the first harvest ranged from 90 cartons/A for 'Agriset 761'
to 346 cartons/A for Fla. 7699. All entries in the medium fruit grade were at or below 103
cartons/A. Average individual fruit weight ranged from 5.8 oz for Fla. 7699 to 8.1 oz for 'Affirm'.
'Affirm' had significantly larger individual fruit weight than fourteen other entries. Cull fruit varied
from 16 to 48% of the total fruit harvested for the entries. The predominant defects of cull fruit were
poor blossom ends and rough fruit.

Second Harvest (May 27): The total marketable yield for the second harvest ranged from 744
cartons/A for ACR 6503 to 1816 cartons/A for 'Flavor More 223' (Table 4). Seven entries were
similar to 'Flavor More 223' in total yield. Extra-large fruit yield ranged from 342 cartons/A for
ACR 6503 to 950 cartons/A for 'Sanibel' and XPH 10047. Fifteen other entries were not
significantly different from XPH 10047 and 'Sanibel' in yield of extra-large fruit at the second
harvest. Large fruit yields ranged from 182 cartons/A for 'Affirm' to 646 cartons/A for 'Flavor More
223'. Average individual fruit weight ranged from 4.9 oz for 'Flavor More 223' to 6.0 oz for
'Affirm'. 'Affirm' had significantly higher individual fruit weight than all but six entries. Cull fruit
varied from between 18 and 35% 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 crack was a particular problem in some entries.

UNHARVESTED OBSERVATIONAL TRIAL

Horticultural Evaluation: All observational entries were rated for numerous horticultural
characteristics (Table 5). Plant and fruit attributes were rated on June 9-10. Ratings provide general
indications of crop performance at a particular location and time.

SUMMARY

Overall, this season's total yields were average based on previous spring yields obtained at
Bradenton (Howe g. al. 1992, 1993, 1994, 1995, 1996). Total seasonal yields ranged from more
than 1800 cartons/A to just less than 2900 cartons/A for the entries in this trial. Extra large fruit
yields for the season were above average based on the previous five spring seasons, where seasonal
yields of extra-large fruit ranged from nearly 1100 cartons/A to more than 2100 cartons/A.











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 527 to 1524 cartons/A with an average of 850 cartons/A among all of
the entries evaluated in trial. This is contrasted with the yields in the spring 1996 which ranged from
51 to 656 cartons/A with an average of 245 cartons/A, and in the spring of 1995 where early extra-
large fruit yields ranged from 262 to 936 cartons/A with an average among the entries of 545
cartons/A (Howe et. al., 1995, 1996).

A single entry stood out at the first harvest, 'Affirm'. It had the greatest extra large fruit yield (1524
cartons/A) of all the entries. It also had good individual fruit weight in fall 1996 trial (Howe al.
1997).

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 1 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.
