FRESH MARKET TOMATO VARIETY TRIAL RESULTS FOR FALL 1984
T. K. Howe, J. W. Scott, and W. E. Waters1
A replicated trial was conducted at the Gulf Coast Research and Education
Center at Bradenton, Florida in the fall of 1984 to evaluate the performance
of various commercial fresh market tomato cultivars and IFAS breeding lines.
Ten of the entries in this trial, 'Sunny,' 'Duke,' 'FTE 12,' 'Hayslip,'
'Independence,' 'Atlantic City,' 'Horizon,' and IFAS breeding lines 7136,
7132, 7130, 7131, and 7133 were also entries in a statewide IFAS variety
testing program at three other agricultural research facilities, Homestead,
Immokalee and Fort Pierce, Florida. A cumulative report on statewide
performance of these entries will be published separately.
Materials and Methods
Sixteen months prior to bed preparation for this trial, the field
was broadcast with 600 lbs. of superphosphate (0-20-0, containing 80 lb/ton
F503 micronutrients) and 1 ton of dolomite per acre. The land was used
for row crop production the following spring. Raised beds of EauGallie
fine sand (1) were formed in mid-August 1984. The 30-inch wide beds were
spaced on 4.5 ft centers with irrigation ditches every 7 rows. Fertilizer
incorporated into the full width of the bed included 18-0-25-2 at 3.4 lb/100
LBF, high calcium lime at 8.1 lb/100 LBF, and superphosphate with F503
at 6.2 lb/100 LBF. Fertilizer, 18-0-25-2 (N-P205-K20-MgO). at 17.5 lb/100
linear bed feet (LBF), was distributed in 2 narrow bands in shallow grooves
on the bed surface 9 inches to each side of the bed center. The beds were
fumigated with MC-33(R) (methylbromide-chloropicrin) at 3.6 lb/100 LBF.
The beds were mulched with white polyethylene plastic.
All entries (Table 1) were sown on July 23, 1984 in wooden flats containing
SAF-T-BLAST(R) (Mineral Aggregates, Inc.), a processed product of spent
coal. Seedlings were transplanted 10 days later into TODDtR) Planter flats
(Speedling, Inc., 1j x 1b x 2 inches, model 150) containing vermiculite
and Canadian peat (1:1) amended:with superphosphate, dolomite and micro-
nutrients. Transplants were set in the field on August 30, 1984. Resetting
was done twice on September 4 and 7. Plants were set 28.5 inches apart
in single rows in the center of each bed and staked. Four replicates of
10 plants per entry were arranged in a randomized complete block design.
Integrated pest management was used for insect population control throughout
the season. Monitor(R) was applied 5 times and Lannate(R) was applied
3 times as insect populations demanded. The serpentine leafminer was the
most serious pest of the season. A regular spray program was followed
as prevention against fungal disease. M-45 R) was used 16 times alone,
twice in combination with Bravo(R) and copper, and once in combination
with Bravo. Bravo was used once alone. Combination sprays were utilized

Breeding), and Center Director, respectively, at GCREC-Bradenton.
with Bravo. Bravo was used once alone. Combination sprays were utilized
to prevent the spread of target spot.
Fruit were harvested by hand on November 26 and December 6, 1984.
Tomatoes were graded as cull or marketable, and the marketable fruit was
sized by machine as: less than 7 x 7 (cull), 7 x 7 (small), 6 x 7 (medium),
6 x 6 (large) and 5 x 6 (extra large) according-to commercial standards.
Both culls and marketable fruit were counted and weighed. Average fruit
weight, percent culls, and percent large and extra large fruit (6 x 6 and
5 x 6 combined) were calculated in addition to yield for each harvest and
for the season.
Results and Discussion
Seasonal rainfall and temperatures are listed in Table 2. Temperatures
for the season were typical according to data collected since 1954 (2).
Rainfall was lower, as compared to 30-year averages, for the months of
September (2.33" vs. 8.27") and October (0.45" vs. 2.79"), while it was
higher for November (3.49" vs. 1.00"). Lighter rainfall had little effect
on production due to use of seepage irrigation.
Cumulative yields for the fall 1984 season are in Table 3. Ten of
the fourteen entries are not significantly different from each other, with
regard to highest marketable yield. The same ten entries had similar large
fruit yield. There was no difference among any of the entries in individual
fruit weight. The fewest culls were produced by Horizon, Atlantic City,
Hayslip, FTE 12, 7136, and 7131.
Yields and fruit size among the cultivars and breeding lines for the
first harvest (November 26, 1984) was similar to the seasonal results (Table
4). Two-thirds of all entries were not significantly different with respect
to maximum yields. Thirteen entries had similar individual fruit weight,
while ten entries had similar large fruit yields. Cull production ranged
from 17.4% (Horizon) to 34.5% (7132) with 8 entries similar to Horizon.
By the second harvest on December 6, 1984, there were fewer differences
among the cultivars and breeding lines tested (Table 5). All entries had
similar marketable yield except 'Sunny' was greater than 7134. There were
no differences among entries in individual fruit size or the percentage
of large fruit contributing to the marketable yield. Only 4 entries differed
from the other 10 in cull production.
No cultivar or breeding line can be singled out as superior for the
season or by individual harvest with regard to marketable yield or fruit
size. All of the commercial cultivars were statistically indistinguishable
from each other by the parameters measured during the fall of 1984.
