HAND HARVEST TOMATO VARIETY TRIALS FOR FALL 1980 AND SPRING 1981

W. E. Waters, T. K. Howe, D. S. Burgis, and J. W. Scott

Two replicated tomato trials were conducted at the Agricultural Research
and Education Center, Bradenton, Florida, to evaluate the performance of various
tomato cultivars and breeding lines during the fall of 1980 and the spring of
1981. Entries included in the trials are listed in Tables 1 and 2.

MATERIALS AND METHODS
All entries were germinated in wooden flats containing SAF-T-BLAST(R) (Mineral
Aggregates, Inc.), a processed proquct of spent coal. Transplanted seedlings were
grown 4 to 6 weeks in Speedling t" trays (1" x 1" cells) containing vermiculite
and transplant peat-lite mix (2:1). Transplants for the fall 1980 trial were
set in the field on September 9, 1980, and some resetting was necessary on
September 11, 1980. The spring 1981 trial was set in the field on March 4, 1981(R)
Both plantings were on raised beds of Myakka fine sand (1), treated with Dowfume
MC-33 at 350 Ibs/acre, fertilized at the rate of 1250 Ibs/acre of 18-0-25-2,
distributed in 2 bands 18 inches apart, and 100 Ibs/acre each of 18-0-25-2,
Uramite' (33% N), and superphosphate (0-20-0) containing 80 lbs/ton fritted
micronutrients (FN 503) broadcast in the center of the bed, and mulched with black
plastic. Plants were set in single rows in the middle of each bed spaced 18"
apart in the fall trial, and 24" apart in the spring. Beds were spaced on 4.5 foot
centers with irrigation ditches every 7 rows. This arrangement resulted in 9685
linear feet of bed per acre. In each trial, 3 replicates of 10 plants per entry
were arranged in a randomized complete block design. Standard pesticides were
applied as recommended for insect and disease control.

Fruits were harvested 3 times during the fall 1980 trial and twice during the
spring 1981 trial. Tomato fruit were sized by machine, counted, weighed, and
graded into cull or marketable fruit.

RESULTS AND DISCUSSION

Fall 1980: 'Florida 2432', a breeding line released for genetic purposes,
was the earliest entry with a first-pick yield of 645.7 30-pound boxes per acre
(Table 1). 'Tempo' and Castle's '1035' were also very early with yields of
473.5 and 464.9 30-pound boxes per acre. The latest entry was 'Hayslip' with a
yield of 92.5 30-pound boxes per acre.
Total yield (marketable yield and culls) for the three harvests ranged
from a high of 3684.6 30-pound boxes per acre to a low of 2167.3 30-pound
boxes per acre for 'Duke' and 'A1875', respectively. 'Duke' also had the best
marketable yield of 2924.8 30-pound boxes per acre. The poorest marketable
yield, 1934.8 30-pound boxes per acre, was produced by 'A2610'. The lowest








percentage of cull fruit were from 'A1875' (10.4%), 'A2610' (10.8%), and 'Walter PF'
(10.9%), respectively. Peto's 'FTE #5' produced the highest percentage of cull
fruit, 31.1%.

The number of marketable fruit ranged from 315,085 per acre from 'A1702'
and 311,211 per acre from 'Tempo' to 217,589.4 per acre from 'Florida 1A'.
Greatest marketable fruit weights were produced by 'Florida 1A' and 'Florida 18'
(5.1 oz/fruit). 'Burgis' produced the smallest fruit with an average weight of
3.9 oz per fruit. The yield of large fruit (5 x 6 and larger) ranged from 2324.4
to 1112.7 30-pound boxes per acre for 'Duke' and 'A2610', respectively. The per-
centage of marketable yield of larger fruit was highest for 'Florida 1A' (84.7%)
and lowest for 'A1702' (54.3%).

The best entry from fall 1980 was 'Duke' which had best total yield,
marketable yield, and yield of large fruit. 'Florida 1A', a new release for
fresh market production, also performed well with the best percentage of large
fruit, the highest number of marketable fruit, and the heaviest fruit.
Spring 1981: In the spring of 1981, 'Duke' was the earliest entry, producing
2280.9 30-pound boxes per acre for the first harvest (Table 2). The second and
third earliest entries were 'Burgis' (2137.2 30-pound boxes per acre) and Florida
breeding line #91914 (2035.5 30-pound boxes per acre). 'Florida IC' was the latest
entry, producing only 1197.9 30-pound boxes per acre.
Total yield ranged from 3648.1 to 2171.1 30-pound boxes per acre for 'Hayslip'
and 'Walter PF', respectively. Best marketable yield was 3128.3 30-pound boxes
per acre from 'FTE #12'. The lowest marketable yield came from 'Walter PF' with
1649.7 30-pound boxes per acre. The percentage of cull fruit ranged from a high
of 41.8% from 'Florida IC' to a low of 9.6% from the Florida breeding line #91914.

'FTE #12' produced the greatest number of marketable fruit (295,392.5/acre)
and 'Florida IC' produced the fewest number (131,716.0/acre). Average fruit
weight was greatest for 'Florida IB' (6.9 oz/fruit) and smallest for 'Walter PF'
(4.6 oz/fruit). Large fruit yield (5 x 6 and larger) ranged from 2537.5 30-pound
boxes per acre from 'Hayslip' to 1523.8 30-pound boxes per acre from 'Florida 1C'.
However, 'Florida lA', 'Florida IB', and 'Duke' produced the highest percentage of
large fruit based on marketable yield, all bearing over 90% marketable yield of
large fruit. 'Walter PF' produced the lowest percentage of large fruit (72.2%).
Best overall performance for the spring 1981 tomato trial came from 'Hayslip'
with the best total yield and large fruit yield, 'FTE #12' with best marketable
yield and greatest number of marketable fruit, and 'Duke' which was the earliest
and had the highest percentage of large fruit.
