BELL PEPPER VARIETY TRIAL FOR SPRING 1993

T. K. Howe and W. E. Watersi

Florida vegetable statistics for 1991-92 indicate that the value of fresh market
green peppers was $170.8 million (1). 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 1991-92, Manatee County ranked fifth and
Hillsborough County sixth in harvested acreage with a total of 3000 acres in the
two counties. A variety trial was conducted at the GCREC in Manatee County
during the spring of 1993 to evaluate yield and horticultural characteristics.

Materials and Methods

Raised beds of EauGallie fine sand were formed on 5 February. The 33-inch wide,
8-inch high beds were spaced 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 (N-P205-K O) at 1307 Ib/A placed in 2 grooves on the
bed surface 12 inches to each side of bed center. Superphosphate (0-20-0 with
80 Ib/ton minor elements as F503) was banded on the false bed at 436 Ib/A. Beds
were fumigated with methyl bromide:chloropicrin (66:33) and covered with black
polyethylene. The entire field was covered again with polyethylene on 8 February
and then again on 15 February due to damage by Sandhill cranes.

Seeds of all entries were sown in vermiculite on 7 January and germinated in the
laboratory. Seedlings were transferred 14 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.

Transplants were set into the field on 25 February in two rows spaced 10 inches
apart with an in-row spacing of 11 inches. Four replications of 20 plants per
entry (24 entries) were arranged in a randomized complete block design. Twelve
additional entries were planted as single plots of 20 plants. A severe storm on


Research Program Coordinator and Center Director, respectively.









12-14 March which included very strong winds (gusts to 70 mph), chilling
temperatures, and rain caused extensive damage to the entire crop. On 18 March
the field was replanted using plants from the initial sowing. However, plants
were set in 2 rows spaced 10 inches apart with an in-row spacing of 22 inches.
This resulted in one-half the plant stand initially planned for the trial.

The crop was scouted for the presence of pests throughout the season. Insect
populations were managed with: methomyl, Bacillus thuringiensis, acephate,
insecticidal soap, oxamyl and dimethoate. However, pepper weevil still caused
significant damage to the crop. 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 19 and 26 May and 2 June. Pickers were
instructed to harvest only the largest, firm green fruit. Fruit was not allowed
to acquire mature color. Total fruit harvested were counted, weighed, and cull
fruit were separated (3) which were then also counted and weighed.

Yields were computed on a weight basis and were expressed in 28-lb bushels.
Qualitative evaluations of horticultural characteristics and disease incidence
were made for all entries prior to the first harvest. A sample of eight
marketable fruit per cultivar and replication was taken 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

Maximum daily temperatures, on average, were 1 to 2 degrees below normal as
compared to the 39-year averages (2) (Table 1). Minimum daily temperatures were
2 to 3 degrees lower than normal in April and equivalent to the 39-year averages
during March and May. However, as mentioned previously, a severe storm in mid-
March caused damage severe enough to replant the field. Rainfall was below
average during March and May, but above average during April.

A complete listing of all entries in both trials along with their sources,
qualitative evaluations of the plants and fruit, and ratings for disease
incidence and overall acceptability are in Table 2. Bacterial spot was not a
problem during this trial, therefore no rating was assigned for the disease.

Replicated Trial. Seasonal yields for three harvests ranged from 389 bushels/A
for FMX 1153 to 889 bushels/A for FM 284 (Table 3). Twelve other entries were
not significantly different form FM 284 in total seasonal yield. The number of
marketable fruit per plant ranged from 2.6 for FMX 1153 to 7.2 for HMX 8862. FM
284, XPH 5963 and PS 3187 were not significantly different than HMX 8862 in the
number of marketable fruit obtained per plant. Average marketable fruit weight
for the season ranged from 5.4 oz for PR 300-3 to 7.5 oz for 'Camelot'. Only
'King Arthur' at 7.0 oz was similar to 'Camelot' in fruit weight. The proportion
of harvested fruit which were culled ranged from 15% for FM 284 to 51% for FMX
1153. Fourteen other entries were not significantly different from FM 284 in low
amount of cull fruit. Plant stand was excellent for all replicated entries.

At the first harvest on 19 May, the marketable yields ranged from 106 bu/A for
PR 300-3 to 346 bu/A for 'Valiant' (Table 4). Twelve other entries were not









significantly different from 'Valiant' in high yield. The number of marketable
fruit per plant ranged from 0.8 for PR 300-3 to 2.0 for 'Valiant'. All but nine
entries were similar to 'Valiant' in the number of fruit harvested per plant.
Average marketable fruit weight ranged from 6.4 oz for PR 300-3 to 9.3 oz for FMX
1153. Only 'Camelot' at 8.6 oz was not significantly different than FMX 1153 in
individual fruit weight. The proportion of cull fruit ranged from 0% for HMX
2660 to 23% for FMX 1153.

Average fruit length ranged from 3.5 inches for 'Ssupersweet 862R' to 4.4 inches
for 'Camelot' and XPH 5963 (Table 5). Fruit width ranged from 3.1 inches for PR
300-3 to 3.7 inches for 'Ssupersweet 862R'. The ratio of fruit length to fruit
width ranged from 1.0 for 'Jupiter' and 'Ssupersweet 862R' to 1.3 for 'Camelot',
XPH 5963, 'Whopper Improved', and PR 300-3. A ratio of 1.0 indicates a blocky
fruit shape. Wall thickness ranged from 0.239 inches for PR 300-4 to 0.296
inches for 'Ssupersweet 862R'. Nine other entries were not significantly
different than 'Ssupersweet 862R' in wall thickness. They were: 'Whopper
Improved', PS 3187, 'Valiant', 'Verdel', 'King Arthur', 'Boynton Bell', PR 300-6,
NVH 3079, and 'Camelot'. The number of lobes per fruit varied from 2.8 to 3.6
with the vast majority averaging at least 3.0 lobes.

At the second harvest on 26 May, marketable yield ranged from 106 bu/A for PR
300-4 to 355 bu/A for PS 3187 (Table 6). Thirteen other entries were not
significantly different from PS 3187 in total marketable yield. The number of
fruit harvested per plant ranged from 0.8 for PR 300-4 to 2.6 for PS 3187.
Fifteen entries were similar to PS 3187 in the number of fruit harvested per
plant. Average marketable fruit weight ranged from 5.2 oz for PR 300-3 to 6.9
oz for 'Ssupersweet 862R' and 'Camelot'. Only six entries were significantly
lower in fruit weight than 'Ssupersweet 862R' and 'Camelot'. The total
proportion of fruit which were cull quality ranged from 9 to 46% at the second
harvest.

The marketable yield at the third harvest on 2 June ranged from 89 bu/A for FMX
1153 to 367 bu/A for FM 284 (Table 7). Only five entries had significantly lower
yields than FM 284. The number of marketable fruit from each plant averaged from
0.8 fruit for FMX 1153 to 3.4 fruit for HMX 8862. Those six entries which
yielded more than two fruit per plant were not significantly different than HMX
8862. The proportion of cull fruit ranged from 25 to 74%. Losses were due to:
undersize/misshapen fruit, pepper weevil damage, lepidoterous larvae damage,
sunscald, virus, and fruit rot, in roughly descending order.

Observational Trial. Of the dozen entries in single plots, seasonal yields
ranged from 431 bu/A for the miniature bell pepper 'Jingle Bells' to 966 bu/A for
the very long processing pepper NS 43504 (Table 8). Those standard bell pepper
entries with yields of at least 700 bu/A should be considered for further
evaluation. They were: HMX 2656, HMX 2659, NS 411, NS 43504, 0324 and 8229.

It should be noted that 'Jingle Bells' had a very good novelty value. The
diminutive fruit were sought after for use in a classroom and for use as an hours
d'oeuvre. One grower commented that he sold 'Jingle Bells' as a potted plant
successfully. 'Jingle Bells' fruit had to be harvested with care because the
stem did not snap easily and pickers often tore open the pods.









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 3). When high early yield (Table 4) and
desirable horticultural qualities such as blockiness and thick walls (Table 5)
are considered, outstanding performance came from: 'Camelot', 'Valiant', and
'King Arthur'.

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.
