PEPPER VARIETY TRIAL RESULTS FALL 1986
Paul H. Everett and Karen A. Armbrester


A replicated field trial was conducted at the Southwest Florida
Research and Education Center, Immokalee, Florida during the fall season
(September December) of 1986 to evaluate the performance of 14 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 (1.5 x 1.5 x 2.5
inch cell size) on August 12, 1986, except for XPH 5489 which was seeded on
August 15, 1986. Entries were transplanted to field plots on September 11,
1986. 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 August 27, 1986, 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. 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 white 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 -K20 fertilizer was 257-92-406 pounds, respectively.
Fruit were harvested on November 24, December 2, and December 11, 1986. At
each harvest fruit were counted, weighed and graded into marketable or cull
fruit. At the first harvest a representative sample of fruit was sorted
according to the number of lobes per fruit and measured for length to

diameter ratio and wall thickness. Bacterial spot was found scattered
throughout the test before first harvest, becoming more severe by second
harvest and causing some leaf drop. The general weather conditions during
this trial are shown in Table 2.

RESULTS AND DISCUSSION

Table 3 shows the marketable yields for each of the 14 entries. First
harvest yields ranged from a high of 788 25-lb bushels/7260 LBF for 'Summer
Sweet Brand 860' to a low of 108 25-lb bushels/7260 LBF for FM262.
Statistically equal to 'Summer Sweet Brand 860' was PSR 14584 at 746 25-lb
bushels/7260 LBF. Third ranking 'Summer Sweet Brand 820' (596 25-lb
bushels/7260 LBF) was significantly higher in yield than all the remaining
entries. Entry FM262 at 526 25-lb bushels/7260 LBF, 'Big Belle' at 404
25-lb bushels/7260 LBF and P-324 at 390 25-lb bushels/7260 LBF were
statistically equal for highest yield at the second harvest. By the third
harvest there were no significant differences in yield. All entries were
statistically equal for total marketable yield.

At first harvest, fruit size ranged from a high of 6.7 ounces per
fruit for 'Summer Sweet Brand 860' to a low of 4.6 ounces per fruit for
FM262 (Table 4). There were few significant differences in fruit size
among the entries at first harvest with ten entries statistically equal for
largest size. Entry FM262 had the smallest size fruit at 4.6 ounces per
fruit. Due to the small fruit size of FM262 many mature fruit of this
variety were left on the plants during the first harvest causing a reduced
first harvest yield (108 25-lb bushels/7260 LBF) and an inflated second
harvest yield (526 25-lb bushels/7260 LBF) for this variety. Entry FM262
also had the smallest fruit at second harvest. 'Jupiter' (5.4 ounces per
fruit) ranked largest in fruit size at the second harvest along with PSR
12085 (5.2 oz.), 'Memphis (5.1 oz.), P-1796 (5.0 oz.), PSR 14584 (4.9 oz.),
XPH 5488 (4.8 oz.), and 'Summer Sweet Brand 820' (4.8 oz). There were no
significant differences in fruit size at the third harvest.

Table 5 shows the number of lobes per fruit, wall thickness and length
to diameter ratio of a random sampling of first harvest fruit from the 14
entries in the trial.
