BELL PEPPER VARIETY TRIAL FOR FALL 1992
T. K. Howe and W. E. Waters'
Florida vegetable statistics for 1991-92 indicate that the value of fresh market
green peppers was $170.8 million (2). Production of 18.8 million bushels came
from 20,600 acres with an average price of $9.09 per bushel. This was the first
time the state average exceeded 900 bushels per acre. The value of green peppers
in Florida was only surpassed by tomatoes during 1991-92.
Pepper production is concentrated in the southwest, southeast and west central
portions of the state (1). During 1990-91, Manatee County ranked fourth in
harvested acreage at 1700 acres (1). A variety trial was conducted at the GCREC
in Manatee County during the fall of 1992 to evaluate yield and horticultural
characteristics.
MATERIALS AND METHODS
Soil in the trial area was sampled before field preparation and analyzed by the
IFAS Soil Testing Lab. The pH (7.3), NH4-N (1 ppm) and NO3-N (2 ppm) were
determined from a water extract (3). While the elements P (23 ppm), K (14 ppm),
Ca (484 ppm), and Mg (77 ppm) were determined from a Mehlich I extract (4). The
soil analysis was unavailable before field bedding operations, however. Raised
beds of EauGallie fine sand were formed August 3. The 33-inch wide, 8-inch high
beds were placed on 5 ft centers with seepage irrigation ditches spaced every 6
beds. An acre was equivalent to 8712 linear ft of bed. Fertilizer included 18-
0-25-2 (N-P2O0-K20-MgO) at 1437 Ib/A placed in 2 grooves on the bed surface 12
inches to each side of bed center. Superphosphate (0-20-0 with 80 lb per ton
minor elements as F503) was banded to the false bed at 523 Ib/A. Beds were
fumigated with methyl bromide (66%):chloropicrin (33%) and covered with white on
black polyethylene.
Seed of all entries were sown in vermiculite on July 9 and germinated in the
laboratory. Seedlings were transferred 15 days later into 1.5 x 1.5 x 2.5 inch
containerized cells containing a peat:vermiculite media (1:1, v:v) amended with
dolomite (11.3 lb), superphosphate (5.6 lb) and hydrated lime (2.8 lb), each per
cu. yd. of media.
'Research Program Coordinator and Center Director, respectively.
Transplants were set into the field on August 21 in 2 rows spaced 10 inches apart
with an in-row plant spacing of 11 inches. After transplanting, plants were
drenched with water. Four replications of 20 plants per entry were arranged in
a randomized complete block design. Plants were staked and tied later in the
season.
The crop was scouted throughout the season. Broad mite, beet armyworm, aphids
and pepper weevil were noted. Only broad mite caused significant crop damage.
It was severe enough to cause leaf and pod growth distortions as well as bud
abortion. Broad mites were rated on September 24 for population density and
plant damage severity. Insect populations were managed with: Bacillus
thuringiensis, methomyl, endosulfan, dicofol, chlorpyrifos, oxamyl, dimethoate
and insecticidal soap. The crop was also treated with mancozeb and tribasic
copper to control bacterial spot and fungal pathogens. Diseases were not a
significant problem.
Fruit were harvested three times on October 26, November 5 and 16, 1992. Pickers
on October 26 harvested only largest green fruit. Harvesting for size meant some
smaller fruit were passed over by pickers and matured to red or yellow by the
second harvest. Total fruit harvested were counted, weighed and gleaned of cull
fruit (9) which were also counted and weighed. Broad mite damaged fruit were
tabulated separately.
Yields were computed on a weight basis and were expressed as 28-lb bushels.
Qualitative evaluations of horticultural characteristics and disease incidence
were made for all entries just prior to the first harvest. A sample of 8
marketable fruit per plot was taken at random from the earliest fruit harvested.
These fruit were measured for length, diameter and pod wall thickness and the
number of lobes were counted.
RESULTS AND DISCUSSION
Temperatures were near normal for most of the season, except that overnight lows
were six degrees above normal in November (Table 1). Rainfall was 53% below
normal in September. While this did not have an effect on irrigation, lower
rainfall alleviated the threat of bacterial spot infection which is usually a
problem in fall plantings.
Seasonal yields for three harvests ranged from 220 bushels/A for 'Capistrano' to
817 bushels/A for 'Whopper Improved' (Table 2). Seven entries were not
significantly different than 'Whopper Improved', they were: 'Ssupersweet 860'
(775 bu/A), 'King Arthur' (688 bu/A), XPH 5936 (663 bu/A), 'Ssupersweet 862 R'
(651 bu/A), PS 55887 (611 bu/A), 'PR 300-3' (597 bu/A) and PR 300-6 (593 bu/A).
Marketable fruit yield per plant ranged from 0.7 for 'Capistrano' to 3.0 for
'Ssupersweet 860'. Eight other entries were not significantly different than
'Ssupersweet 860' in fruit yield per plant, all exceeding 2.1. Average
marketable fruit weight ranged from 5.3 oz for HMX 8862 and RNK 9140 to 7.1 oz
for 'Boynton Bell' and 'Whopper Improved'. Twelve entries with fruit weight of
6.2 oz or greater were not significantly different than 'Boynton Bell' or
'Whopper Improved'. The proportion of harvested fruit which were culled for
defects and/or damage, including broad mite induced deformities, ranged from 18%
for 'Whopper Improved' to 54% for 'Capistrano'. Ten entries were similar to
'Whopper Improved' in the percentage of total culls, all at or under 35%. Broad
mite induced damage to fruit was analyzed as a separate cull fruit category.
Mite damaged fruit ranged from less than 1% for 'Whopper Improved' to 35% for PR
300-4. The percentage of fruit culled for broad mite damage did not always
correspond to visual ratings from September 24.
At the first harvest on October 26, the marketable yields ranged from 33 bu/A for
RNK 9140 to 246 bu/A for 'King Arthur' (Table 3). 'Ssupersweet 860' (201 bu/A),
XPH 5936 (200 bu/A), PR 300-6 (189 bu/A) and 'Whopper Improved' (181 bu/A) were
not significantly different than 'King Arthur' in total marketable yield, and all
averaged more than 0.5 fruit per plant. The highest yielding entries at the
first harvest did not necessarily have the greatest individual fruit weights.
Fruit weight ranged from 5.2 oz for PR 300-4 to 8.0 oz for 'Capistrano'.
Thirteen other entries were similar to 'Capistrano' in individual fruit weight.
Total cull fruit yield as a percentage of total harvest ranged from 8% for 'King
Arthur' to 67% for 'Capistrano'. Broad mite damaged fruit accounted for between
0 and 60% of the total harvested fruit.
Fruit dimensions of marketable fruit were quantified from a sample of the
earliest fruit harvested (Table 4). Average fruit length ranged from 3.2 inches
for 'Ssupersweet 862 R' and 'Orobelle' to 4.3 inches for 'Bell King'. 'Bell
King' fruit were significantly longer than any other entry. Fruit width ranged
from 2.9 inches for RNK 9140 to 3.6 inches for 'King Arthur'. Fourteen other
entries were not significantly different than 'King Arthur' in average fruit
diameter. The ratio of fruit length to width ranged from 0.9 for 'Ssupersweet
862 R' and 'Orobelle' to 1.5 for 'Bell King', where 1.0 indicates a blocky fruit
shape. No other pepper entry had a ratio as high as 'Bell King'. Twenty entries
of the 25 in trial were within 0.1 of a 1.0 fruit ratio. Wall thickness ranged
from 0.214 inches for XPH 5936 to 0.266 inches for 'Whopper Improved'. Only two
other entries, PR 300-10 (0.256 in.) and 'Boynton Bell' (0.252 in.) were not
significantly different than 'Whopper Improved' in fruit wall thickness.
'Whopper Improved' has consistently had thick walled fruit in past trials (5-7).
All entries averaged at least 3.1 lobes per fruit, none exceeded 3.8.
At the second harvest on November 5, yields increased for all entries except
'Verdel' and 'Jupiter' (Table 5). Marketable yield ranged from 92 bu/A for
'Capistrano' to 381 bu/A for 'Whopper Improved'. 'Ssupersweet 860' (373 bu/A),
'King Arthur' (340), PR 300-3 (331), XPH 5936 (300) and 'Ssupersweet 862 R' (297)
were not significantly different in marketable yield than 'Whopper Improved'.
Thirteen entries were not significantly different in yield than 'Capistrano'.
Marketable fruit per plant ranged from 0.3 to 1.5 with eight entries producing
one or more marketable fruit per plant. Average individual fruit weight ranged
from 5.0 oz for HMX 8862 to 8.7 oz for 'Whopper Improved'. Only 'Capistrano'
(7.7 oz), PR 300-6 (7.6 oz), 'Boyton Bell' (7.5 oz) and 'Memphis' (6.8 oz) were
not significantly different than 'Whopper Improved' in individual fruit weight.
Ten to 58% of the total fruit harvested was culled, with from less than 1 to 34%
of the fruit culled due to broad mite damage.
On November 16, the third harvest, yields decreased for all entries except PS
55887 (Table 6). Marketable yield ranged from 62 bu/A for PR 300-4 to 255 bu/A
for 'Whopper Improved'. All but six entries were similar to 'Whopper Improved'
in yield at this time. Marketable fruit weight ranged from 4.5 oz for 'Orobelle'
to 6.8 oz for 'Camelot'. Nineteen entries were similar to 'Camelot' in fruit
weight. Fruit which were culled accounted for between 24 and 58% at the third
harvest. Broad mite damaged fruit contributed less to cull percentages than
small and deformed fruit.
Of the 29 entries in the single plot, observational trial, seasonal yields ranged
from 24 bu/A to 861 bu/A (Table 7). Only five entries did not fall within the
yield range of the replicated trial (Table 2). Eleven entries exceeded 560 bu/A
and showed promise of competing among the best yielding entries of the replicated
trial. However, some of these entries were not of the preferred type which
produce blocky fruit (ratio = 1.0). Two entries exceeded an average of 4 lobes
per fruit.
Summary: Best seasonal performance came from those entries which combined high
yield with high average fruit weight and a low proportion of cull fruit. Several
entries showed these qualities (Table 2). When high early yield (Table 3) and
desirable horticultural qualities such as blockiness and thick walls (Table 4)
are considered, outstanding performance came from: 'Whopper Improved' (slightly
long fruit), 'Ssupersweet 862 R' and PR 300-6. Those with slightly less thick
walls, but very strong seasonal and early yields included: 'Ssupersweet 860' and
'King Arthur'. While XPH 5936 had exceptional yields, the wall thickness and lobe
number was less than desirable.
'Whopper Improved', 'King Arthur' and 'Ssupersweet 860' have also performed well
during the spring and fall of 1991 (5,6).

The Gulf Coast Research and Education Center
The Gulf Coast Research and Education Center is
a unit of the Institute of Food and Agricultural Sci-
ences, University of Florida. The Research Center
originated in the fall of 1925 as the Tomato
Disease Laboratory with the primary objective of
developing control procedures for an epidemic out-
break of nailhead spot of tomato. Research was ex-
panded in subsequent years to include study of sev-
eral other tomato diseases.
In 1937, new research facilities were established
in the town of Manatee, and the Center scope was
enlarged to include horticultural, entomological, and
soil science studies of several vegetable crops. The
ornamental program was a natural addition to the
Center's responsibilities because of the emerging in-
dustry in the area in the early 1940's.
The Center's current location was established in
1965 where a comprehensive research and extension
program on vegetable crops and ornamental plants is
conducted. Three state extension specialists posi-
tions, 16 state research scientists, and two grant
supported scientists from various disciplines of
training participate in all phases of vegetable and
ornamental horticultural programs. This interdisci-
plinary team approach, combining several research
disciplines and a wide range of industry and faculty
contacts, often is more productive than could be ac-
complished with limited investments in independent
programs.
The Center's primary mission is to develop new
and expand existing knowledge and technology, and
to disseminate new scientific knowledge in Florida, so
that agriculture remains efficient and economically
sound.
The secondary mission of the Center is to assist
the Cooperative Extension Service, IFAS campus
departments, in which Center faculty hold appropri-
ate liaison appointments, and other research centers
in extension, educational training, and cooperative
research programs for the benefit of Florida's pro-
ducers, students, and citizens.
Program areas of emphasis include: (1) genetics,
breeding, and variety development and evaluation;
(2) biological, chemical, and mechanical pest manage-
ment in entomology, plant pathology, nematology,
bacteriology, virology, and weed science; (3) produc-
tion efficiency, culture, management, and counteract-
ing environmental stress; (4) water management and
natural resource protection; (5) post-harvest physiol-
ogy, harvesting, handling and food quality of horti-
cultural crops; (6) technical support and assistance to
the Florida Cooperative Extension Service; and (7)
advancement offundamental knowledge of disciplines
represented by faculty and (8) directing graduate
student training and teaching special undergraduate
classes.
