FRESH MARKET TOMATO VARIETY TRIAL RESULTS FOR FALL 1982

T. K. Howe, J. W. Scott and W. E. Waters1


A replicated fresh market tomato variety trial was conducted at the Agri-
cultural Research & Education Center in Bradenton, Florida to evaluate the per-
formance of various commercial cultivars and IFAS breeding lines in the fall of
1982. Ten of the entries in the trial, 'Castlehy 1035,' 'Sunny' (formerly #674),
'Duke,' 'Flora-Dade,' 'FTE 12,' 'Hayslip,' 'Walter PF,' 'Burgis,' and two IFAS
breeding lines, 827015-IBK, and D76127, were also;a part of a statewide IFAS
variety trial. These ten entries were evaluated at IFAS Agricultural Research
facilities in Quincy, Ft. Pierce, Gainesville, Immokalee, Homestead and Bradenton,
and a cumulative report covering the results of all six locations will be reported
separately.

MATERIALS AND METHODS

Field preparation, three months prior to bedding, consisted of the addition
of dolomite at one ton/A and 600 lbs/A superphosphate (0-20-0) containing 80 lbs/
ton micronutrients (503 oxide). Raised beds of IMyakka fine sand (1) were treated
with Dowfume MC-33 at 3.6 lbs/100 linear bed ft. Bed fertilizer included 20.6 0
lbs/100 linear bed ft of 18-0-25-2 distributed in two bands 18 inches apart on the
bed surface. Full bed surface dressing included 18-0-25-2 (1.4 lbs/100 linear bed
ft), IitrofornP (38-0-0 at 1.4 lbs/100 linear bed ft), and superphosphate (0-20-0)
containing 80 lbs/ton 503 oxide micronutrients (1 lb/100 linear bed ft). The
30-inch wide beds were mulched with black plastic which was sprayed with white
latex paint to reduce the temperature under the mulch.

All entries (Table 1) were sown on July 22, 1982 in wooden flats containing
SAF-T-BLAST0 (Mineral Aggregates, Inc.), a processed product of spent coal. Seed-
lings were transplanted eleven days later to SpeedlingG trays (1" x 1" cells)
containing a vermiculite and peat mix (1:1) amended with superphosphate, minor
elements and potassium nitrate. Transplants were set in the field on Sept. 2,
1982. Resetting was necessary and final resetting occurred 13 days after initial
transplanting. Plants were set 24" apart in single rows in the middle of each bed
and staked. Beds were spaced on 4.5 foot centers with irrigation ditches every
7 rows. Four replicates of 10 plants per entry were arranged in a randomized
complete block design. Standard pesticides were applied for insect and disease
control.

Fruits were.hand harvested on November 29, Dec. 6, and Dec. 13, 1982.
Tomatoes were graded as cull or marketable, and marketable fruit was sized by
machine. Both cull and marketable fruit were counted and weighed. Defects of
the cultivars were noted during the grading procedure. Average fruit weight,
% culls and % large fruit (6 x 6 or greater) were calculated.

Five mature green fruit were chosen from grade 6 x 6 or larger and placed
in an ethylene ripening room on.the morning following the third harvest for each
of the following cultivars: Sunny, Duke, FTE 12, Hayslip, Burgis, Walter PF,
Castlehy 1035, and Flora-Dade. Ethylene gas was maintained at a.concentration
of 100 ppm. The room varied from 40-705 relative humidity and 70-770F. Fruit
were removed after 5.9 days when most fruit were pink (commercially, mature green
fruit are gassed from 0 to 4 days).- Fruit were then table-ripened at room temp-
erature (approximately 720F). External color was measured on the day of removal
from the ripening room and daily for three days after removal from ethylene.
Color was determined using a Hunter Lab Color/Difference Meter (Model D25-2).
Each fruit was measured on two sides and the blossom end on each day. By the
third day, the fruit were judged to be over-ripe (accelerated ripening due to
extended ethylene treatment) and measurements were concluded.

RESULTS AND DISCUSSION

Results are in Tables 1 through 5. Data for the entire fall 1922 season
are summarized in Table 1. Individual-harvest data for harvests 1, 2 and 3 are
given in Tables 2, 3 and 4, respectively. Marketable yields are singled out
for each harvest to show the season's production trends in Table 5.

Cumulative results for the fall 1982 fresh market tomato season appear in
Table 1. No single entry showed significantly better performance than all others
in the trial. Sunny, FTE 12, and Duke were amohg the top yielding entries.
These three produced similar fruit size, number of culls and yield of large
fruit. Two promising IFAS breeding lines, 827061 and 827060 had significantly
fewer culls, larger fruit size and yielded more large fruit than the majority
of other trial entries.

Earliness data is contained in Table 2. Breeding line 827061 produced sig-
nificantly higher marketable yield than fifteen other entries at the first harvest.
With fruit size of 6.9 oz and only 7' culls, 827061 warrants further attention by
breeders. Another line, 827060, was similar in.performance. Both 827061 and
827060 were superior to Sunny and FTE 12 in fruit size and matched their per-
formance in other categories at the first harvest. However, 827061 and 827060
produced h5% of their total seasonal yield at the first harvest, while Sunny and
FTE 12 seasonal yields were divided somewhat equally among all harvests (Table 5).

By the second harvest, Duke and Sunny ranked as the top two entries for
marketable yield, which were significantly greater than all but five other
entries. Duke had 44h of its seasonal production harvested at the second
picking (Tables 3 and 5).

Late performance was impressive for Hybrid 58 which ranked first in marketable
yield (significantly greater than fourteen other entries) for the third harvest
(Table 4). Again, Sunny and FTE 12 were among top yielding entries. IFAS breeding
line 827025-SBK, which steadily increased production throughout the season, ranked
fifth in spite of low large fruit production. IFAS breeding line 827024-11 which
produced 45% of total marketable yield at the third picking ranked fourth.











Ripening as judged by color, after ethylene exposure of selected cultivars,
was generally not significantly different (Figures 1-8). There was great varia-
bility among individual fruit within cultivars with the exception of Sunny which
showed better uniformity among fruit. There was significant difference between
Sunny and Duke in the degree of ripening, as determined by the ratio of red (a)
to yellow (b) color, from the termination of gassing through the final measure-
ment.
