In 1993-94, 49,600 acres of tomatoes were harvested in Florida yielding 66.4
million 25-pound cartons worth $472 million (Fla. Agr. Stat. Serv., 1995).
Tomatoes accounted for 30% of the total production value for all vegetables grown
during 1993-94, once again 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 the spring of 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, seven entries were harvested as single plots to estimate
yield, and an additional 59 entries were evaluated visually in 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-P205-K20) 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
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 348 Ib/A.
This fertilizer regime provided a 1:2 ratio of N:KO2 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 black
polyethylene.
Transplant Production: Seeds were sown on January 12, 1995 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) then covered with a layer of coarse vermiculite. 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 23 and spaced 24
inches apart in single rows down the center of each bed. Transplants were
immediately drenched with water containing imidacloprid to control silverleaf
whitefly populations. 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 and single plot harvest trial. Plants
were staked and tied without pruning.

July 1995
Plants were scouted for pests throughout the season. Lepidopterous larvae,
citrus thrips, leafminers and silverleaf whitefly were the primary insects found.
Bacillus thuringiensis, permethrin, esfenvalerate, insecticidal soap, avermectin,
endosulfan, methamidophos, fenpropathrin, chlorpyrifos and azadirachtin were used
according to label instructions to control insect pest populations during the
season. A spray program using mancozeb, copper salts and chlorothalonil was
followed for control of bacterial and fungal-incited diseases.
Fruit of the replicated entries were harvested at the mature-green stage or
beyond on May 11, May 23, and June 5. 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 for various categories
defining plant and fruit characteristics were given to the observational entries
at the end of the season on June 6 and 7, when red ripe fruit were present on the
vine.
RESULTS & DISCUSSION
Weather information for the season compared to the 40-year averages (Stanley,
1994) is in Table 1. Maximum and minimum daily temperatures, on average, were
above normal as compared to the 40-year averages during the entire season. March
and May deviated most from the normal temperatures, being three to four degrees
above normal during the day and four to six degrees above normal at night.
Rainfall was below average during March and May and twice the average in April.
Although June weather data is not on the table, the first four days of June just
prior to the final harvest, 4.52 inches of rain fell.
REPLICATED TRIAL
Seasonal: Total marketable yield among all entries after three harvests ranged
from 1850 25 Ib-cartons/A for 'Mountain Fresh' to 2644 cartons/A for 'Equinox'
(Table 2). Seventeen other entries were not significantly different from
'Equinox'. All entries exceeded the 1993-94 State average of 1340 cartons/A
(Fla. Agr. Stat. Serv., 1995). Yield of extra-large fruit ranged from 892
cartons/A for 'Bonita' to 1863 cartons/A for 'Merced'. Sixteen other entries
were similar to 'Merced' in extra-large fruit yield for the season. Yield of
large fruit ranged from 295 cartons/ A for XPH 10046 to 675 cartons/A for Fla.
7514. Average individual fruit weight ranged from 5.4 oz for 'Sunny' to 6.9 oz
for XPH 10046. 'Merced' (6.7 oz), 'Sunbeam' (6.6 oz) and RXT 3096 (6.5 oz) were
not significantly different from XPH 10046 in average seasonal fruit weight.
Cull fruit accounted for 24-43% of total harvest with eight entries (HMX 4700,
'Equinox', 'Sunpride', 'Sunbeam', RXT 3002, RXT 3096, Fla. 7658 and 'Mountain
Fresh') with 30% or less culled fruit. Only 'Sunny' produced more than 40% cull
fruit.
First Harvest (May 11): Total marketable yield for the first harvest ranged from
378 cartons/A for 'Sunny' to 1014 cartons/A for 'Merced' (Table 3). Fla. 7578,
HMX 4700, HMX 2824, Fla. 7658, 'Agriset 761', Fla. 7514 and RXT 3096 were not
significantly different from 'Merced' in total yield at the first harvest.
Extra-large fruit yield ranged from 262 cartons/A for 'Sunny' to 936 cartons/A
for 'Merced'. Only Fla. 7578 (778 cartons/A), HMX 4700 (696) and HMX 2824 (687)
were similar to 'Merced' in extra-large fruit yield. Average individual fruit
W weight ranged from 6.3 oz for 'Sunny' to 7.8 oz for XPH 10046. Thirteen other
entries were similar to XPH 10046 in average fruit weight at the first harvest.
Cull fruit accounted for 11-41% of the total fruit harvested at the first pick.
The predominate defects of cull fruit were misshapen fruit (many flattened),
rough shoulders and nippled blossom ends, in decreasing order.
Second Harvest (May 23): The total marketable yield for the second harvest
ranged from 943 cartons/A for XPH 10046 to 1642 cartons/A for 'Equinox' (Table
4). Only four entries were significantly lower in yield than 'Equinox'. -Extra-
large fruit yield ranged from 474 cartons/A for 'Bonita' to 1117 cartons/A for
'Equinox'. Thirteen other entries were not significantly different from
'Equinox' in yield of extra-large fruit at the second harvest. Large fruit
yields ranged from 147 cartons/A for XPH 10046 to 440 cartons/A for 'Sunny'.
Average individual fruit weight ranged from 5.3 oz for 'Bonita' and 'Sunny' to
6.9 oz for XPH 10046. Only two entries, 'Merced' and 'Sunbeam' (6.5 oz), were
similar to XPH 10046 in average fruit weight at the second harvest. Cull fruit
accounted for between 20 and 35% of the total harvest.
Third Harvest (June 5): Marketable yield at the third harvest ranged from 156
cartons/A for 'Bonita' to 566 cartons/A for RXT 3096 (Table 5). Fifteen entries
yielded as well as RXT 3096 at this harvest. Extra-large fruit yields ranged
from 50 cartons/A for 'Bonita' to 318 cartons/A for XPH 10046. Ten entries
yielded as well as XPH 10046 in the extra-large fruit category at this harvest.
Average marketable fruit size ranged from 4.8 oz for 'Merced' to 5.8 oz for XPH
*10046. Fifteen entries were not significantly different from XPH 10046 in fruit
size at this time. Cull fruit accounted for 45 to 70% of the harvest.
HARVESTED OBSERVATIONAL TRIAL
Seasonal: Total marketable yield among the harvested observational entries
ranged from 1462 cartons/A for FM 207 ESL to 2899 cartons/A for FM 215 ESL
(Table 6). Extra-large fruit yield from these entries ranged from 849 cartons/A
for FM 207 ESL to 2397 cartons/A from FT 4023.
UNHARVESTED OBSERVATIONAL TRIAL
Horticultural Evaluation: All observational entries were rated for numerous
horticultural characteristics when most fruit were beyond mature green (Table 7).
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 that size fruit generally secures a premium price. Overall
seasonal yields of extra-large fruit exceeded 1700 cartons/A for: 'Merced',
'Equinox', RXT 3096 and Fla. 7578, although other entries were not significantly
different from these entries. Additionally, earliness can be a key to
profitability if one grower brings fruit to market ahead of competitors. Best
early extra-large fruit yields came from 'Merced', Fla 7578, RXT 3096, HMX 4700
and HMX 2824.
'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). Fla 7578 is a heat
tolerant hybrid and has done well in a previous fall trial (Howe, et. al.,
1994b). '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., 1992, 1993, 1994a, 1994b).

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