STAKED TOMATO VARIETY TRIAL RESULTS FALL 198

Paul H. Everett and Karen A. Armbrester1 U E LIBRARY

Immokalee AREC Research Report IMM84-2 4aioh,j93l 4

A replicated trial was conducted at the Agricultural Rese .h/ ati o
Center, Immokalee, Florida, during the fall season (August-Dec q.brorida
evaluate the performance of twenty tomato cultivars and/or breeding lines. Tab e
1 is a list of entries and seed sources used in this trial. Hereafter, breeding
lines from BradentonGCREC and Homestead-TREC will be identified by the first
numerical sequence only.

EXPERIMENTAL PROCEDURE

All entries were seeded in ToddR planter trays #150 (1.5 inch cell size) on
August 8, 1983, and were transplanted to field plots on September 2, 1983. Field
plots were arranged in randomized complete blocks with four replications of each
entry. Each plot consisted of 10 plants spaced 15 inches apart in the row on
raised plant beds spaced 6 feet on centers. Plant beds were irrigated with an
open ditch seep system with lateral ditches spaced 41.5 feet apart. There were 5
plant beds between lateral ditches. All plots were fertilized with 6.1 lb of
triple superphosphate (45% P205)/100 linear bed feet applied on the flat in a 5
foot swathe to coincide with the plant beds, 7 lb of 5-8-8-1.2 + micronutrients/100
linear bed feet applied in a 30 inch wide band on a pre-bed and bedded over to a
depth of 3-4 inches, and 14 Ib of 19-0-30/100 linear bed feet applied on the sur-
face of the finished bed in a narrow band 10 inches to each side of the plant row.
The plant beds were fumigated with VorlexR at 21 ounces/100 linear bed feet and
then mulched with white plastic film. Plants were staked but not pruned. Fung-
icides were applied on a 5-7 day schedule and insecticides were applied on a need
basis. General weather conditions during this trial are shown in Table 2. Insects
were not a serious problem but early blight disease became moderately severe
between the first and second harvests. Tomatoes were harvested on November 30 and
on December 13, 1983. At each harvest fruit were graded, sized, counted and
weighed. Per acre yields in this report are based on 7,260 linear feet of plant
bed.

RESULTS AND DISCUSSION

There were significant differences among the entries in marketable yield and
average fruit weight (Table 3). Marketable yields (total of the two harvests)
ranged from a high of 4100 25 lb boxes/A for PSR 46480 to a low of 2476 25 lb
boxes/A for D79000. PSR 46480 produced significantly higher yields than 9 entries
and 'Hayslip', closely followed by PSR 74180, had yields that were significantly
higher than 7 entries. Yields from 'FTE 12' were significantly better than the 4
lowest yielding entries.

Average weight of fruit for the first harvest (Table 3) ranged from 8.3 oz
for 7065 to 5.3 oz for D79000. Entries 7065 and 7060 ranked significantly larger
in size than all other entries. Entry 7057 and 'Duke' ranked third and fourth,

respectively, in size and were significantly larger than eight of the remaining
entries. D79000 was significantly smaller than all other entries.

For the second harvest fruit weights ranged from 5.4 oz for 7065 to 4.1 oz
for D79000. Entry 7065 was significantly larger than 15 entries, and 7060 retained
its rank as second largest in size and was significantly larger than 14 of the
entries."

Entry 803148 had the lowest percentage (2.1%) of cull fruit and D79000 had
the highest (15.0%) (Table 3). Five of the 20 entries had cull percentages in the
0-5% range, 11 entries were in the 5-10% range, and 4 entries were in the 10-15%
range.

Categories of cull fruit, by harvest, are shown in Table 4. Radial cracking
(CR) at the stem end was responsible for the highest percentage of cull fruit in
both the first and second harvests. 'Atlantic City' had the highest percentage
of cracking in both harvests followed by AVX 8384 and E423. Leaky blossom-end-
scars (BES) were responsible for some cull fruit in the first harvest, but was
of minor importance in the second harvest. Oddshape, zipper scars, cat facing
and speck accounted for some culls but were not a serious problem. Other
categories such as decay and scarring accounted for a considerable number of
fruit in both harvests.

Table 5 shows the percent (by weight) of the total marketable fruit in each
of four size categories. Entry 7065 (94.3%) had the highest percentage large
plus extra large fruit followed by 7060 (93.3%), PSR 74180 (91.3%), 'FTE 12'
(9.8%) and 'Atlantic City' (88.7%).
