PEPPER VARIETY TRIAL RESULTS Winter 1982-83

Paul H. Everett and Karen A. Armbresterl

A replicated field trial was conducted at the Agricultural Research Center,
Immokalee, Florida, "during the winter season (Nov. 1932-March 1933) to evaluate
the performance of 15 pepper cultivars and/or breeding lines. Table 1 shows
the list of entries and corresponding seed sources used in this trial.

EXPERIMENTAL PROCEDURE

All entries were seeded into Speedling trays (1', inch square cells) on,
September 28, 1982, and were transplanted to field plots on November 1, 1982.
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
apart. 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 Oct. 15, all plots were fertilized with 5-8-8-1.8 + micro -
nutrients at 6.9 lb/100 linear bed feet and 19-0-30 at 13.8 lb/100 linear bed
feet.

The 5-8-8-1.8 fertilizer was spread in a 30 inch band on a pre-bed then-bedded
over to a depth of 4 inches. The 19-0-30 fertilizer was banded on each shoulder
of the finished bed 9 inches from the plant rows. The finished bed was then
mulched with black plastic film. Total amount of fertilizer N and K20 were 3.0
and 4.7 pounds per 100 linear bed feet, respectively. Preplant soil tests
indicated high levels of available phosphorus, therefore only a maintenance
application of 40 pounds of P205 was included in the fertilizer program. On
the basis of 7,260 linear bed feet per acre, the N-P20r-KPO'fertilizer was
215-40-340 pounds, respectively. Fungicides were applied on a 5-7 day schedule
and insecticides were applied on a need basis. Insects and viruses were not a
serious problem in this test, however, bacterial spot (Xanthomonas vesicatoria)
was present at light to moderate levels throughout the "eason. Fruit were
harvested on Jan. 25, Feb. 16, and larch 9, 1983. At each harvest fruit were
counted,'weighed and graded into marketable or cull fruit. The general weather
conditions during this trial were coot windy and very wet (Table 2).

RESULTS

Table 3 shows the.marketable yields for each of the 15 entries. First harvest
yields from 8 of the entries; 'Hybrid Giant Ace', 'Gator Belle', 'Bell Tower',
'Big Belle', P7110, P130, 'Espadon', and 'Early Calwonder' were statistically
equal and ranged from 1157 bushels/acre for 'Hybrid Giant Ace' to 890 bushels/acre
for 'Early Calwonder'. Lowest first harvest yields were with UCX 4018 (531 bu/A)
and 'Four Corners' (510 bu/A). At the second harvest, yields from P7118 and UICX
4018 were higher than yields from the other entries. With 'Gator Belle', third
harvest yield was considerably higher than second harvest yield and was significant:
higher than third harvest yields from the other entries. Highest total marketable
yield in this trial was from 'Gator Belle' (1839 bu/A), but this was not
statistically different from P7118 (1610 bu/A) or Espadon (1589 bu/A).

At the first and second harvests, 9 entries were statistically equal in
average fruit weight (Table 4), which ranged from 6.3 ounces/fruit for P7118 and
'Bell Tower' to 5.6 ounces for 'Early Calwonder' at the first harvest, and from
6.3 ounces/fruit for 'Gator Belle' to 5.1 ounces for 'Espadon' and 'Big Belle' at
the second harvest. Average fruit weight of 5 entries, P7113, NCX 4012, E1211,
'Bell Tower' and P130, held up well at the third harvest.

The percent fruit at first harvest with 3 or 4 lobes is shown in Table. 4.
Entry P7118 had the highest percent fruit with 4 lobes, but the fruit was long and
tapering, with rather thin walls. Entry E1211 also had a high percent of 4 lobed
fruit which were thick walled and blocky. Although 'Gator Belle' had a low
percentage of 4 lobed fruit, it did have a high percentage of 3 lobed thick walled
and blocky fruit that rated high in overall appearance. 'Gator Belle' exhibited a
small amount of cuticle cracking which appeared.oto be associated with the most
mature fruit.










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