BELL PEPPER VARIETY TRIAL FOR FALL 1991

T. K. Howe and W. E. Waters1

Twenty-four sweet bell pepper varieties and breeding lines were evaluated in a
replicated yield trial in the fall of 1991 at the Gulf Coast Research and
Education Center in Bradenton, FL. In addition, twelve varieties and breeding
lines were harvested for yield estimates from single, unreplicated plots.

MATERIALS AND METHODS
Soil in the trial area was sampled before field preparation and analyzed by the
IFAS Soil Testing Lab: pH 6.5; water extractable (saturated paste method)
elements, P = 15.6, K = 7.4, Mg = 49.1 and Ca = 279 ppm (2). Beds 32 inches wide
and 9 inches high on 5 ft centers were formed August 12. Superphosphate (0-20-0
plus minor elements as F503 oxide at 80 Ib/ton) was banded 12 inches to each side
of bed center 4 inches deep at 523 Ib/A (Acre = 8712 linear feet of bed). Two
bands of 18-0-25-2 were placed in shallow grooves on the bed surface 12 inches
to each side of the bed center at 1568 Ib/A. The beds were fumigated with
methylbromide:chloropicrin (67:33) at 214 Ib/mulched A (8712 x 2.7 ft) and
covered with white on black polyethylene mulch. Land was seepage irrigated from
ditches spaced every six beds.

Seed of all pepper entries (Table 2) were sown on July 11 into plastic trays
containing coarse vermiculite. Seedlings were transplanted 12 days later to
containerized plant flats (1.5 x 1.5 x 2.5 inches) containing peat and
vermiculite (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.

Transplants were set into the field beds on August 26 in two rows spaced 10
inches apart with an in-row plant spacing of 11 inches. At transplanting, plants
were watered with a fertilizer solution (20-20-20 at 3 lb/100 gal water). There
were four replications of 20 plants per plot arranged in a randomized complete
block design. Observational plots contained 8 plants.

Insect populations were monitored throughout the season. Predominant insect
pests during the season in order of severity of damage were: armyworm, broad
mite, sweetpotato whitefly, and aphids. Applications of labeled pesticides were
utilized for control of these pests, however, armyworm damage was severe and

caused fruit abortion and reduced marketable yields. A preventive spray program
utilizing maneb with or without copper was followed for control of bacterial and
fungal pathogens. Bacterial leaf spot was not a problem. Paraquat was applied
post transplant between the beds for weed control.

Green or red fruit were picked on November 5, 18, 26, and December 9. Pickers
on November 5 harvested only the largest green fruit. Therefore harvesting for
size meant some smaller fruit matured by the second harvest, when size was also
emphasized along with any fruit with mature color. Total fruit harvested and
cull fruit were counted and weighed. Worm damaged and virus infected (mosaic)
cull fruit were tabulated separately to quantify the extent of yield reduction
due to these factors.

Yields were computed on a weight basis and were expressed as 28-lb cartons.
Yields were adjusted to ignore harvested fruit with feeding damage from
armyworms. However, as mentioned above, worm damage fruit was tallied separately
and reported to show the extent of the problem and document cultigen differences,
if any. Qualitative evaluations of horticultural characteristics and disease
incidence were made for all entries prior to harvest. A sample of eight
marketable fruit per plot was selected at random from the first harvest. 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 the entire production period (Table 1).
Rainfall was significantly below the 38-year averages for the whole season.
Consequently, there was no evidence of bacterial leaf spot as the season
progressed.

Characteristics of plants and fruit along with ratings for disease incidence and
overall acceptability for each entry are in Table 2. These qualitative
evaluations were made on a single replication for each entry on November 12.

Seasonal yields for four harvests (Table 3) ranged from 272 cartons/A for 'Pek
Bell' to 1086 cartons/A for 'King Arthur'. Thirteen entries with yields of 724
cartons/A or greater were not significantly different than 'King Arthur'.
Although stated yields were adjusted to ignore worm damage to fruit of
harvestable size, many fruit aborted before harvest due to worm damage and this
was impossible to quantify. The number of marketable fruit per plant ranged from
1.7 for 'Pek Bell' to 6.9 for 'King Arthur'. Twelve entries with 4.8 fruit per
plant or more were not significantly different than 'King Arthur'. Average
individual fruit weight ranged from 3.9 oz for 'Crispy' to 5.1 oz for 'Whopper
Improved'. Fruit weights of 4.7 oz or greater were not significantly different
than that for 'Whopper Improved'. Total fruit categorized as culls proportionate
to total fruit harvested ranged from 43% for 'Bell Captain' to 90% for 'Pek
Bell'. Total proportion of harvested fruit culled due to worm damage ranged from
27% for 'Bell Captain' to 55% for 'Capistrano'. 'Pek Bell' produced more cull
fruit than any other entry. Only 'Ssupersweet 860', FMX 1154 and 'Bell Captain'
were significantly lower in the proportion of cull fruit damaged by worms than
'Capistrano'. Cull fruit with virus-like symptoms observed as reddish-brown
mottled streaks and puckering of the pod wall ranged from 0% for 'Crispy', 'PR
300-7' and 'King Arthur' to 28% for FMX 1154 and 'Pek Bell'. Only 'Bell King'
at 11% was not significantly different than FMX 1154 and 'Pek Bell'.

At the first harvest on November 5, yield ranged from 113 cartons/A for 'Pek
Bell' to 717 cartons/A for 'Bell King' (Table 4). Those entries not
significantly different in yield from 'Bell King' included: 'Ssupersweet 860',
'PR 300-7', 'King Arthur', 'Whopper Improved', 'Verdel', PS 3187, 'PR 89-3',
'Orobelle' and 'Ranger'. The number of marketable fruit per plant at the first
harvest ranged from 0.5 for 'Pek Bell' to 3.5 for 'Bell King'. Average fruit
weight ranged from 4.1 oz for 'Crispy' to 5.4 oz for 'Whopper Improved'.
Seventeen entries were similar to 'Whopper Improved' in average fruit weight.
The proportion of total fruit harvested which were culled for any reason ranged
from 37% for 'Bell Captain' to 83% for 'Pek Bell'. Eighteen entries were similar
to 'Bell Captain' in the proportion of cull fruit. The proportion of harvested
fruit showing worm damage ranged from 34% for 'Bell Captain' to 70% for 'Pek
Bell'. Only 'Pek Bell' and 'Galaxy' were significantly different than 'Bell
Captain' in the proportion of worm damaged fruit at the first harvest. Virus
symptoms were expressed in 17 entries, but only 'Memphis' (9%) and FMX 1154 (6%)
were not significantly lower than 'Pek Bell' (13%) in the proportion of fruit
showing mosaic symptoms.
Marketable fruit dimensions for entries in replicated trial appear in Table 5.
Fruit length ranged from 3.0 inches for 'Orobelle', 'Memphis' and PSX 55887 to
4.2 inches for 'Bell King'. Fruit of 'Bell King' was significantly longer than
any other entry in trial. Fruit width ranged from 2.8 inches for 'Galaxy',
'Rebell', and 'Crispy' to 3.3 inches for 'King Arthur' and 'PR 89-3'. 'Bell
King' had the greatest length to width ratio at 1.4. Six entries, 'King Arthur',
'Ssupersweet 860', PSX 55887, 'Capistrano', 'Jupiter' and 'Memphis' had length
to width ratios (L/W) of 1.0, but these were not significantly different than 6
other cultigens with L/W ratios of 0.9 or 1.1. Wall thickness ranged from 0.185
inches for 'Ranger' to 0.224 inches for 'Whopper Improved'. 'Whopper Improved'
had significantly thicker pod walls than any other entry. The number of lobes
per fruit ranged from 3.3 for 'PR 300-7' to 4.0 for 'Whopper Improved'.
Seventeen other entries were not significantly different than 'Whopper Improved'
with respect to the number of lobes per fruit.

Marketable yield at the second harvest 13 days after the first pick and following
cooler weather, ranged from 49 cartons/A for 'Early Calwonder' to 234 cartons/A
for 'Crispy' (Table 6). Ten other entries were similar to 'Crispy' in yield at
the second harvest. The number of marketable fruit per plant ranged from 0.5 to
2.3 for 'Pek Bell' and 'King Arthur', respectively. Average fruit weight was
lower and ranged from 3.6 oz for 'Pek Bell' to 5.0 oz for 'PR 89-3'. The
proportion of total harvested fruit which were culls ranged from 49 to 82%, with
worm damaged fruit ranging from 22-67% of all fruit harvested. Virus symptoms
were severe for FMX 1154, 'Pek Bell', 'Memphis' and 'Bell King'.

On November 26, marketable yield ranged from 40-221 cartons/A for 'Pek Bell' and
'Crispy', respectively. The number of marketable fruit per plant ranged from 0.2
to 1.3 for 'Pek Bell' and 'Crispy', respectively. Only PSX 55887 and 'Belmont'
were not significantly different than 'Crispy' in the number of marketable fruit
per plant. 'Whopper Improved' with fruit averaging 5.4 oz was only significantly
different from seven entries with average fruit weights of 4.3 oz or lower. At
this time, total culls as a percentage of all harvested fruit ranged from 36 to
95%. The proportion of worm damaged fruit ranged from 14% for 'Bell King' to 64%
for 'Rebell'. Thirteen entries were not significantly different than 'Bell King'
with respect to- the amount of worm-damaged fruit. Fruit damaged by virus

symptoms accounted for 0-41% of fruit harvested, where less than 22% fruit loss
was significantly lower than the 41% loss from FMX 1154.

At the fourth harvest on December 9, the yields were lowest of the season,
ranging from 26 to 181 cartons/A for FMX 1154 to 'King Arthur', respectively
(Table 8). Variability was so great that few differences existed among the
entries with respect to yield. Total cull fruit percentages were still high,
however damage attributable to worms was much less than previous harvests. More
fruit at this time were culled due to small size and misshapen pods.

Table 9 has harvest and fruit characteristic information for observational
entries. While HMX 7660 is a smaller fruited type with pale yellow fruit turning
red, the yield per plant was excellent.

Summary: Although this particular trial sustained serious fruit damage inflicted
by worms, more realistic yields were approximated by adjusting yield data to
ignore fruit harvested with worm damage. Data was adjusted with the assumption
that worms affected the entire trial area uniformly with rare exception (Table
4). Resultant adjusted seasonal yields were generally higher than the commercial
average in west-central Florida of 610 cartons/A (1). Singular performance came
from 'King Arthur', 'Ssupersweet 860', 'PR 300-7', 'Whopper Improved',
'Orobelle', 'Verdel', PS 3187, 'Bell King', 'PR 89-3' and 'Ranger'. All had high
seasonal and first harvest yields. 'Whopper Improved' had excellent wall
thickness. Qualitative plant and fruit characteristics in Table 2 highlight
other important factors.

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 ofdisciplines
represented by faculty and (8) directing graduate
student training and teaching special undergraduate
classes.
