PEPPER VARIETY TRIAL RESULTS SPRI 198 4'

Paul H. Everett and Karen A. Armbre L.rA.S.-Univ. Of !,:l .

A replicated field trial was conducted at the Agricultural Research and
Education Center, Immokalee, Florida during the spring season (Feb.-May 1984)
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 inch cell size)
on December 22, 1983, and were transplanted to field plots on February 8, 1984.
Field plots were arranged in a randomized complete block design with four
replications of each entry. Each plot consisted of 22 plants in a double row
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
January 9, 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. Due to a delay caused by light rain the beds were fertilized with
19-0-30 at 13.8 lb/100 LBF on January 11. The 19-0-30 fertilizer 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 then mulched with
black plastic film. Total amount of fertilizer N and K20 were 3.0 and 4.7 pounds
per 100 LBF, respectively. A maintenance application of 1.1 pounds of P205 per
100 LBF was included in the fertilizer program. On the basis of 7,260 LBF per
acre the N-P205-K20 fertilizer was 215-80-340 pounds, respectively. Fruit were
harvested on May 14 and May 22, 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 14 entries. First
harvest yields ranged from a high of 2154 bushels/7260 LBF for 'Melody', which
was significantly higher in yield than all but one other entry, to a low of 1148
bushels/7260 LBF for 'Valley Giant' which was significantly lower in yield than

11 of the other 13 entries. Statistically equal to 'Melody' (2154 bushels/7260 LBF)
was 'Bell Tower' at 1905 bushels/7260 LBF. 'Bell Tower' ranked second highest
in yield but was significantly higher in yield than only 3 of the remaining
12 entries. Yields from all entries were statistically equal at the second
harvest. The second harvest yields ranged from a high of 440 bushels/7260 LBF
for 'Greene Belle' to a low of 139 bushels/7260 LBF for 'Melody'. Although
'Melody' had the lowest yield for the second harvest, it had the highest total
marketable yield in this trial at 2297 bushels/7260'LBF. 'Melody' was not
statistically different from 'Bell Tower' (2130 bushels/7260 LBF), 'Liberty
Belle' (2115 bushels/7260 LBF), 'Bell Captain' (2115 bushels/7260 LBF), 'Greene
Belle' (2087 bushels/7260 LBF), 'Gator Belle' (2012 bushels/7260 LBF), and
XPH 5017 (1976 bushels/7260 LBF).

In the first harvest, four entries that were statistically equal in fruit
size, had significantly larger fruit than the remaining 10 entries (Table 4).
Ranking highest in average fruit size was 'Bell Captain' (7.2 oz/fr), followed
by P1000 (7.2 oz/fr), 'Jupiter' (6.9 oz/fr), and 'Melody' (6.8 oz/fr). In the
second harvest 'Melody' (5.3 oz/fr) ranked significantly higher in average
fruit weight than the remaining 13 entries.

The percentage fruit at first harvest with 3 or 4 lobes is shown in Table 4.
'Skipper' had the highest percentage of fruit with 4 lobes. Two varieties,
'Bell Captain' and 'Jupiter', had 3 lobed fruit that were blocky and were
considered as good in overall appearance as the 4 lobed fruit. The multiple
lobed fruit of P1000 were considered to have a good overall appearance.

Table 5 shows the wall thickness and length to diameter ratio of first
harvest fruit from the 14 entries in this trial.
