FRESH MARKET TOMATO VARIETY TRIAL RESULTS FOR FALL 1983
T. K. Howe, J. W. Scott, and W. E. Waters1
A replicated trial was conducted at the Gulf Coast Research and Education
Center in Bradenton, FL to evaluate the performance' of various commercial fresh
market tomato cultivars and IFAS breeding lines in the fall of 1983 (Table 1).
Twelve of the entries in the trial, 'Sunny,' 'Duke,' 'FTE 12,' 'Hayslip,'
'Flora-Dade,' 'Walter PF,' and six IFAS breeding lines were also part of the
statewide IFAS variety trial and were also evaluated at IFAS agricultural research
facilities at Homestead, Immokalee and Ft. Pierce. A cumulative trial report on
the results from all locations will be published separately.
materialss and methodss
Fourteen months prior to making beds the field was broadcast with one ton of
dolomite and 600 pounds of superphosphate (0-20-0 containing 80 pounds/ton
micronutrients as 503 oxide) per acre. The area was farmed in row crops (broccoli)
between this soil treatment and the initiation of the fall 1983 tomato trial.
Raised beds of Eau Gallie fine sand (1) were fumigated with methyl bromide-
chloropicrin (66%-33%) as DowfumeO MC-33 at 3.6 lb/100 linear bed feet.
Fertilizer, as 17.5 lb/100 linear bed feet of 18-0-25-2, was distributed in 2
narrow bands on the bed surface 9 inches to each side of the plant row. Full bed,
surface dressing included 18-0-25-2 at 3.4 lb/100 linear bed feet and super-
phosphate (0-20-0 with microelements at 80 lb/ton as 503 oxide) at 6.2 lb/100
linear bed feet. The 30-inch wide beds spaced on 4.5 ft centers with irrigation
ditches every 7 rows were mulched with white plastic.
All entries were sown on July 25, 1983 in wooden flats containing SAF-T-BLAST?
(Mineral Aggregates, Inc.), a processed product of spent coal. Seedlings were
transplanted 10 days later into TODIO Planter flats (Speedling, Inc., model #150,
l1 x 1l x 2") containing vermiculite and Canadian peat mix (1:1) amended with
superphosphate, dolomite, and minor elements. Transplants were set in the field
on August 29, 1983. Re-setting occurred until Sept. 8, 1983. Plants were set
30 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 (IPM) was used for insect control throughout
the season. Pydrin (cyano-(3-phenoxyphenyl)methyl-4-chloro-alpha-(1-methylethyl)
benzeneacetate) was applied 5 times and Monitor (0-S-dimethyl phosphoramidothioate)
was applied 3 times as insect population thresholds demanded. Initially, M-450
(maneb + ZnSOO) and later an M-45 + Benlated benomyll) combination were used twice
a week for disease control. Copper was applied once on November 15.
Fruits were harvested by hand on November 21, November 28 and December 5, 1983.
Tomatoes were graded as cull or marketable, and the marketable fruit was sized by
machine. Both culls and marketable fruit were counted and weighed. Average fruit
weight, percent culls and percent large fruit (6 x 6 and larger) were calculated
in addition to yields.

Results and Discussion
Seasonal rainfall and temperatures are listed in Table 2. Cumulative results
for the fall 1983 season appear in Table 3. IFAS breeding line,7067, 'FTE 12' and
'Walter PF' were the top ranked entries in marketable yield, although only
significantly different from 4 other entries. The line,7067 is being considered as
a commercial release. The greatest percentage of large fruit came from IFAS
breeding lines 7060 and 7065, with 87% and 82%, respectively, and average fruit size
of 6.2 oz and 5.8 oz, respectively. The line 7065 is being considered as a home
garden release. The fewest culls (10%) were produced by 7060.
Yield and performance data are provided for each harvest in Tables 4, 5, 6'and
7. The information from the first harvest (Table 4) and first harvest yields as a
percentage of seasonal yields (Table 7) give an indication of the earliness of the
entries tested. Breeding lines 7067, 7060 and 7065 and 'FTE 12' were among the top
ranking entries in early marketable yield. Line 7067 was significantly earlier than
7 other entries while 7060, 7065 and 'FTE 12' were significantly different from
2 to 3 entries. Average fruit size ranged from 7.0 oz and 6.5 oz (7060 and 7065)
to 3.8 oz (D79000). The IFAS breeding lines 7060 and 7065 also produced the
greatest percentage of large fruit (96.8% and 92.2%, respectively), significantly
greater than all other entries except 7067 and 'Duke.'
By the second harvest, marketable and total yields of all entries were
yielding equally (Table 5). However, there were differences among them in the
proportion of large fruit. IFAS breeding lines 7060, 7065, 7057 and 'Duke' were
the top ranked large fruit producers based on the percentage of marketable yield.
Cull production was lowest for 7060, which was significantly lower than 8 other
entries.
At the final harvest (Table 6), 'Walter PF' was ranked highest in marketable
yield, but greater than only 2 entries. The lines 7060 and 7065 continued to
produce the greatest proportion of large size fruit, with average fruit weight of
5.5 oz and 5.1 oz, respectively.
Early yield, as reflected in greater than 50% of the total yield being
harvested on November 21, came from 7067, 7060, 803148, 7057, D79000 and 7065, all
of which are IFAS breeding lines (Table 7). 'FTE 12' was the only commercial
cultivar to produce nearly 50% of its total marketable yield at the first pick.
The proportion of mid-season fruit production was greatest. for 'Flora-Dade' and
'Sunny.' Only 'Walter PF' had most of its fruit production at the last harvest,
but that production was very close to yields of the first.two picks, so that
'Walter PF' yielded uniformly throughout the season. 'Sunny' followed a similar
trend for uniform yields among the three harvests.
