PEPPER VARIETY TRIAL RESULTS SPRING 1987
Paul H. Everett and Karen A. Armbrester : ,s y Of Forida


A replicated field trial was conducted at the Southwest Florida
Research and Education Center, Immokalee, Florida, during the spring season
(February-May) of 1987 to evaluate the performance of 18 bell 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 in ToddR planter trays #150 (1.5x1.5x2.5 inch
cell size) on December 17, 1986, and were transplanted to field plots on
February 10, 1987. Field plots were arranged in a randomized complete
block design with four replications of each entry. Each plot had 20 plants
arranged in double rows with 10 inches between plants and 10 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 52 feet apart.
There were 6 plant beds plus a drive middle between lateral ditches.
Reported yields are based on 7260 linear bed feet (LBF). On January 27,
1987, all plots were fertilized with 5-16-8-1.8 + micronutrients at 7.9
lb/100 LBF spread in a 30 inch band on a pre-bed then bedded over to a
depth of 3-4 inches. On January 28, 1987, the 19-0-30 fertilizer at a
total of 16.5 lb/100 LBF was banded on each shoulder of the finished bed 10
inches from the plant rows. The finished bed was then fumigated with
Vorlex at 21 ounces/100 LBF and mulched with black plastic film. Total
amount of fertilizer N and K 0 was 3.5 and 5.6 pounds per 100 LBF,
respectively. On the basis of 7,260 LBF per acre the N-P 0 -K 0 fertilizer
was 257-92-406 pounds, respectively. Fruit were harvested on May 6 and May
14, 1987. At each harvest fruit were counted, weighed and graded into
marketable or cull fruit. At second harvest cull fruit were separated into
three categories; button and flat fruit, sunburn, and other (decay, scars,
and odd-shape). The general weather conditions during this trial are shown
in Table 2.


RESULTS AND DISCUSSION

-. Table 3 shows the marketable yield for each of the 18 entries. First
harvest yields ranged from a high of 744 25-lb bushels/7260 LBF for PSR
14584 to a low of 125 25-lb bushels/7260 LBF for FM262. Statistically
equal to PSR 14584 was PSR 17885 at 721 25-lb bushels/7260 LBF. Nine
entries were statistically equal to each other for highest second harvest
yields. They are 'Gator Belle' (676 25-lb bushels/7260 LBF), 'Crispy'

Brand 860' (575), HXP 3647 (544), 'Big Belle' (537) and 'Memphis' (516).
Seven entries were statistically equal for highest combined first and
second harvest yields. They are 'Gator Belle' (1258), PSR 14584 (1216),
'Summer Sweet Brand 860' (1153), XPH5489 (1136), 'Crispy' (1129), PSR 17885
(1077), and XPH 5488 (1056).

At first harvest, fruit size ranged from a high of 6.9 ounces per
fruit for PSR 17885 to a low of 5.0 ounces per fruit for FM262 (Table 4).
Statistically equal to PSR 17885 for heaviest fruit weight was 'Jupiter' at
6.3 ounces per fruit. These same two entries had the heaviest fruit at the
second harvest; PSR 17885 at 5.1 ounces per fruit and 'Jupiter' at 4.7
ounces per fruit.

Table 5 shows the percent cull fruit at first and second harvest and
percent cull fruit in each of three categories at second harvest. Cull
production was considerable at the second harvest ranging from a high of
83.1 percent for P-324 to a low of 12.3 percent for 'Crispy'. This may
have been due to windy, wet weather conditions during the latter part of
March and cold nights during the first six days of April affecting fruit
development. Entries P-324 (76.9%) and 'Summer Sweet Brand 820' (72.2%),
both yellow maturing varieties, had the highest percentage of button and
flat fruit. 'Jupiter' (45.7%) and 'Early Calwonder' (42.0%) produced
statistically less button and flat fruit than P-324 and 'Summer Sweet Brand
820' but statistically more than the remaining 14 entries except P-1796
(38.3%)
