PEPPER VARIETY TRIAL RESULTS SPRING 1982

Paul H. Everett and Karen A. Armbresterl

A replicated field trial was conducted at the Agricultural Research Center,
Immokalee, Florida, during the spring season (Jan. May) of 1982 to evaluate
the performance of ten pepper cultivars and/or breeding lines. Table 1 is a
list of entries and corresponding seed sources used in this trial.

EMPERIiENTAL PROCEDURE

All entries were seeded into Speedling trays (1i inch square cells) on
December 16, 1981, and were transplanted to field plots on January 26, 1932.
Field plots were arranged in a randomized complete block design with three
replications. Each plot consisted of 24 plants in a double row with 10 inches
between plants and 12 inches between rows on raised plant beds spaced 6 feet on
centers. Plant beds were irrigated with an open ditch seep system with lateral
ditches spaced 40 feet apart. Reported yields are based on 7,260 linear bed
feet per acre. On Jan. 25, all plots were fertilized with 5-3-3-1.3 + micro-
nutrients at 6.9 lb/100 linear bed feet and 13-0-25 at 13.8 lb/100 linear bed
feet. The 5-3-8-1.8 fertilizer was spread in a 30 inch band on a pre-bed then
bedded over to a depth of 4 inches. The 13-0-25 fertilizer was banded on each
stioulder of the finished bed 9 inches from the plant rows. The finished bed was
then mulched with black plastic film. Fungicides were applied on a 5-7 day
schedule and insecticides were applied on a need basis. Diseases or insects were
not a serious problem in this test. Fruit were harvested on April 13, Hay 3, and
May 18, 1932. At each harvest fruit were counted, weighed and graded into
marketable or cull fruit.

RESULTS

Table 3 shows the yields for each of the 10 entries. First harvest yields
were higher for 'Gator Belle', PSR 3475, 'Skipper' and 'Big Bertha'. The lowest
first harvest yield was with IOX 4013. Second harvest yields from 'Gator Belle'
and PSR 3475 were higher than yields from other entries at the second harvest.
With 'Gator Belle', third harvest yield was slightly higher than second harvest
yield and was significantly higher than the third harvest yield from the other
entries. For total yield 'Gator Belle' was significantly better than all other
entries, followed by PSR 3475, 'Big Bertha' and 'Skipper'.

Average weight of fruit (Table 4) held up well over three harvests for
PSR 3475, 'Gator Belle', 'Big Bertha' and 'Skipper'. The percent fruit with 3 or
4 lobes is also shown in Table 4. 'Citadel' had the highest percent fruit with
4 lobes, but it was considered too flat with overall poor fruit shape. Although
'Gator Belle' had a high ratio of 3 to 4 lobe fruit, it graded high with respect
to overall appearance.

Table 5 gives a few comments on each entry concerning overall fruit shape,
appearance and length to diameter ratio at the first harvest.

In summary, the most promising entries in this trial included 'Gator Belle',
'Skipper' and PSR 3475.

Table 5. Annotation



Early Calwonder Standard variety. Blocky, mostly 3 or 4 lobed with length to
diameter ratio of 1.01.

Big Bertha Hybrid. Not blocky. Large fruit, mostly 3 and 4 lobed but long
and tapering. Length to diameter ratio of 1.51. Fruit walls tended to be
concaved.

iot as long and tapering as Big Bertha. Length to diameter ratio of 1.29. Fruit
sized well at second and third harvests.

harvest equal to second harvest. Rated best in trial.

Citadel Hybrid. Hedium to small fruit that tended toward flatness, with a
length to diameter ratio of 0.35. Rated poorest in trial, due mainly to fruit
shape.
