PEPPER VARIETY TRIAL RESULTS SPRING 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 spring
season (February May) of 1986 to evaluate the performance of 17
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 #100A
(1.0x1.0x3.0 inch cell size) on December 18, 1985, and were
transplanted to field plots on February 5, 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 8 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 41.5 feet
apart. There were 5 plant beds between lateral ditches. Reported
yields are based on 7260 linear bed feet (LBF). On January 16,
1986, all plots were fertilized with 5-16-8-1.6 + micronutrients at
6.9'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 17, 1986, 19-0-30
fertilizer at a total of 13.8 lb/100 LBF was banded on each shoulder
of the finished bed 10 inches frpm 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 U were
3.0 and 4.7 pounds per 100 LBF, respectively. On the basis of 7,260
LBF per acre the N-P205-K,0 fertilizer was 215-80-340 pounds,
respectively. Fruit were harvested on April 23, May 6, and May 19,
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.
The general weather conditions during this trial are shown in Table
2.

RESULTS AND DISCUSSION

Table 3 shows the marketabale yields for each of the 17
entries. First harvest yields ranged from a high of 828 25-lb
bushels/7260 LBF for P324 to a low of 244 bushels/7260 LBF for
MA 79259. Statistically equal to P324 were ACX 820 (762
bushels/7260), 'Shamrock' (758), 'Gator Belle' (680), 'Marengo'
(653), XPH 5020 (645), 'Melody' (619), 'Four Corners' (584), ACX 860
(579), and P1000 (575). Yields from all entries were statistically
equal at the second harvest and at the third harvest. Total
marketable yields ranged from a high of 2152-25 lb bushels/7260 LBF
for ACX 860 to a low of 1394 25-lb bushels/7260 LBF for MA 79259.
ACX 860 was significantly higher in yield than 6 of the remaining
entries.

Nine entries had the heaviest fruit at the first harvest (Table
4). They are ACX 860 (5.6 oz), .P324 (5.2), 'Mission Belle' (5.2)
P1000 (5.2), 'Melody' (5.1), 'Marengo' (5.1) 'Bell Tower' (5.1),
ACX 820 (5.1), and 'Jupiter' (5.0). Three of these entries retained
their heavy fruit size for the second harvest 'Marengo' (6.3 oz),
ACX 860 (6.1), and 'Melody' (5.9). At the third harvest 'Bell
Tower' (4.7 oz), P1000(4.5), 'Jupiter' (4.4) and ACX 8520 (4.2) had
the heaviest fruit.

Table 5 shows the number of lobes per fruit, wall thickness and
length to diameter ratio of first harvest fruit from the 17 entries
in the trial. 'Mission Belle' (6.9 mm), P324 (6.6), 'Gator Belle'
(6.4) and 'Four Corners (6.4) had the thickest walled fruit.
'Melody' and 'Marengo' had the most elongate fruit.
