PEPPER V ETY TRIAL RESULTS FALL 1984
Paul H ve tt and Karen A. ArmbresterI

A replicated field t was con ted at the Agricultural Research and
Education Center, Iok Forida g the fall season (Sept.-Dec. 1984)
to evaluate the perform o p cultivars and/or breeding lines.
Table 1 shows the li o entes corresponding seed sources used in this
trial. /

/I-V1E NTAL PROCEDURE

All entries we seeded ToddR planter trays #150 (l.5xl.5x2.5 Inch cell
size) on August 8, 19 a ere transplanted to field plots on September 7,
1984. Field plots were a ed in a randomized complete block design with four
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 16,
1984, all plots were fertilized with 5-16-8-1.2 + 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 17, 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 pounds, respectively. Fruit were harvested on November 14, November 26,
and December 11, 1984. At each harvest fruit were counted, weighed and graded
into marketable or cull fruit. The general weather conditions during this trial
are shown in Table 2.

RESULTS

Table 3 shows the marketable yields for each of the 15 entries. First
harvest yields ranged from a high of 764 bushels/7260 LBF for P1001 to a low
of 396 bushels/7260 LBF for both XPH 5019 and 'Skipper'. P1000 at 661 bushels/
7260 LBF and XPH 5020 at 649 bushels/7260 LBF were statistically equal to P1001
(764 bushels/7260 LBF) with these three entries having significantly higher yields
than the other 12 entries. Yields from all entries were statistically equal at
the second harvest, third harvest and for the total yield.

In the first harvest P1000 and 'Bell Captain' were significantly heavier
than 8 of the remaining 13 entries (Table 4). In the second harvest P1000 wa
significantly heavier than 7 of the remaining 14 entries and 'Bell Captain' tas
significantly heavier than 2 of the entries. There were no significant
differences in fruit weight at 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 15 entries in the trial. 'Shamraock'
and XOH 5020 had the highest percentage of 4-lobed fruit. XPH 5020 along with
ACX-830430 had the thickest walls.
