PEPPER VARIETY .TRIAL RESULTS FALL 1985
Paul H. Everett and Karen A. Armbrester1

A replicated field trial was conducted at the Southwest Florida Research and
Education Center, Immokalee, Florida during the fall season (Sept.-Dec. 1985) to
evaluate the performance of 14 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 9, 1985, and were transplanted to field plots on September
11, 1985. Field plots were arrangediin a randomized complete block design with
three replications of each entry. Each plot had 22 plants arranged in double rows
with 8 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 41.5 feet apart. There were 5 plant beds between lateral
ditches. Reported yields are based on 7260 linear bed feet (LBF).. On August 26,
1985, all plots were fertilized with 5-16-8-1.8 + micronutrients at 6.9 lb/100
LBF spread in a 30 inch band on a pre-bed then bedded over to a depth of 4 inches.
On August 27, 19-0-30 fertilizer at a total of 13.8 lb/100 LBF was banded on each
shoulder of the finished bed 9 inches from the plant rows. The finished bed was
then fumigated with VorlexR at 21 ounces/100 LBF and mulched with white plastic
film. Total amount of fertilizer N and K20 were 3.0 and 4.7 pounds per 100 LBF,
respectively. On the basis of 7,260 LBF per acre the N-P205-K20 fertilizer was
215-80-340 p unds, respectively. Fruit were harvested on November 21, December 3,
md December 18, 1985. At each harvest fruit were counted, weighed and graded into
marketable or cull fruit. The general weather conditions during this trial are
ihown 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 1129 bushels/7260 LBF for P1001 to a low of 701
bushels/7260 LBF for MA79259. Eight entries, ACx860, 'Gator Belle', P324, ACX820,
ACX8520, 'Jupiter', P1000, and 'Bell Captain', were statistically equal to P1001
and ranged from a high of 1093 bushels/7260 LBF for ACX860 to a low of 970 bushels/
7260 LBF for 'Bell Captain'. Yields from all entries were statistically equal at
the second harvest and at third harvest. 'Gator Belle' at 1905 bushels/7260 LBF
had the highest total marketable yield in this trial but was significantly higher
in yield than only 5 of the remaining entries.

Five entries, ACX860, 'Jupiter', 'Bell Captain', ACX8520, and P1000,
consistently had the heaviest fruit throughout the season and were statistically
equal to each other in average fruit weight throughout the season (Table 4).
At the first harvest 'Jupiter' (6.2 oz) had the heaviest fruit and was
significantly heavier than 9 of the remaining entries. 'Bell Captain' with
the heaviest fruit in the second and third harvests, was significantly
heavier than 8 entries in the second harvest, and 9.entries in the third harvest.

Table 5 shows the number of lobes per fruit, wall thickness and length
to diameter ratio of first harvest fruit from the 14 entries in the trial.
'Early Calwonder' had the highest percentage of 4-lobed fruit. P1001 had
the thickest walled fruit and MA79259 had the thinnest walled fruit.
