CUBANELLE PEPPER VARI TY T e 199O

T. K. Howe and W. E. Waters'
A replicated variety trial was conducted on cubanelle pepper at the Gulf
Coast Research and Education Center, Bradenton, FL in the spring of 1990.
Six entries were included in this trial.

Materials and Methods
Bed Preparation: Raised beds of EauGallie fine sand were formed on
January 31, 1990. The 32-inch wide, 8-inch high beds were spaced on 5-
ft centers with 6 beds between seepage irrigation ditches. Fertilizer
included 15-0-30-2 (N-P205-K20-MgO) at 1917 Ib/A (Acre = 8712 linear feet
of bed) distributed into 2 narrow bands in shallow grooves on the bed
surface 10 inches to each side of the bed center and a full bed-width,
false bed application of superphosphate (0-20-0 with 80 Ibs per ton minor
elements as F503) at 697 Ib/A. This fertilizer regime provided a 1:2
ratio of N:K20 with approximately 288 lb N/A. This land was originally
intended for tomato production and the K20 fertilizer rate was in excess
of that generally used for pepper production at this location (1). Beds
were fumigated with methyl bromide:chloropicrin (67%:33%) at 216
Ib/mulched A (mulched A = 8712 x 2.7 ft) and mulched with white on black
polyethylene film.
Seed of all pepper entries were sown on January 4, 1990 into plastic trays
containing coarse vermiculite. Seedlings were transplanted 18 days later
to containerized plant flats (cells 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 Ib), each per cu. yd. of
media.
Transplants were set into the field on February 21, 1990 in a single row
(because land had been prepared for tomato production) with an in-row
plant spacing of 8 inches. At transplanting, plants were watered with
20-20-20 fertilizer at 5 lb/100 gal water. There were four replications
of 15 plants per plot arranged in a randomized complete block design.
Plants were staked and tied in mid-April to prevent lodging.
Insecticides were utilized on demand when periodic scouting indicated pest
thresholds had been exceeded. Predominant insect pests during the season
were beet armyworm, sweetpotato whitefly, aphid, and thrips. Appropriately


'Program Coordinator and Center Director, respectively.








timed applications of labelled pesticides were utilized for these pests.
A preventative spray program utilizing maneb with or without copper was
followed for control of fungal and bacterial pathogens. Paraquat was
applied post transplant to the row middles for weed control.

Fruit were picked on May 9, 16, 24, and 31 and June 7 as green fruit.
Pepper fruit were graded as cull or marketable based on U.S. standards for
grades for bell pepper, since guidelines for cubanelles were not
available. Marketable fruit (by these guidelines) were firm, free from
damage or disease, well shaped, and typical for the cultivar. Generally,
plant diseases were not a problem, however, symptoms typical of viral
infection were evident in foliage and fruit in some entries, but
identification was inconclusive. Aphids and sweetpotato whiteflies were
both present in the field, therefore vectors of various viral diseases
were available. To estimate virus-like damage, cull fruit with brown
streaks or puckering were separated from other cull fruit. Beet armyworm
was the most destructive insect pest. Worm-damaged cull fruit were
tabulated separately to quantify the extent of yield damage. Total fruit
harvested and cull fruit were counted and weighed. A sample of eight
marketable fruit per plot was selected at random from the first harvest.
These fruit were measured for length, diameter, and wall thickness, and
the number of lobes were counted. Yields were computed on a weight basis
and were expressed as 28-lb cartons.

RESULTS AND DISCUSSION
General weather information is presented in Table 1. During the spring
1990 production season, temperatures were warmer from February through May
as compared to the 35-year averages (2). With the exception of February,
rainfall was less for the season compared to the 35-year averages.

Seasonal yields (Table 2) ranged from 938 cartons/A for 'Carousel' to 1577
cartons/A for 'Flavor Fry'. 'Key Largo', 'NK 9145' and 'Astrione' were
not significantly different from 'Flavor Fry' in seasonal yield. The
number of marketable fruit per plant ranged from 10.3 for 'Espana' to 18.9
for 'Astrione'. 'Flavor Fry', 'NK 9145' and 'Key Largo' were similar to
'Astrione' in fruit yield per plant. Average fruit weight was greatest
for 'Espana' with 4.1 oz and least for 'Carousel' at 2.4 oz. Cull
production for the season averaged 23% for all entries in trial. The
percentage of all culls damaged by worms was similar for all entries and
was about 10% on average. Virus-like symptoms were not detected on fruit
of 'Flavor Fry', but accounted for 18% of the total culls in 'Key Largo'.

Marketable fruit dimensions were measured for the earliest fruit and are
given in Table 3. 'NK 9145' produced the longest fruit at 6.6 inches,
while 'Carousel' produced the shortest fruit at 4.2 inches. Fruit width
was greatest for 'Espana' at 2.9 inches and least for 'Astrione', 'NK
9145', 'Key Largo' and 'Carousel' at 2.1 or 2.2 inches. The ratio of
fruit length to width was greatest for 'NK 9145' (3.0), 'Astrione' (2.9)
and 'Key Largo' (2.9) and least for 'Flavor Fry' (2.2), 'Espana' (2.0) and
'Carousel' (1.9). Wall thickness was similar for all entries at 4.2 mm
on average. Fruit lobe number ranged from 2.9 for 'NK 9145' to 3.5 for
'Espana'. Pod color at the immature stage was: light yellow for
'Astrione' and 'Carousel'; light lime green for 'Flavor Fry' and 'Key









Largo'; lime green for 'NK 9145' and dark green (as for bell pepper) for
'Espana'. Other characteristics noted were that 'Carousel' had a tapered
bell shape, 'Espana' was quite variable in shape and did produce bell
shaped fruit, and 'NK 9145' was very lumpy i.e., the walls were not
smooth.

Marketable yields by harvest were not significantly different among the
entries for the first two harvests (Table 4). By the third harvest
production peaked for all entries except 'Carousel'. 'Flavor Fry' and
'Astrione' had greater yields at the third harvest than 'Key Largo',
'Espana' and 'Carousel', while 'NK 9145' had greater yields than only
'Carousel'.

Average fruit weight was greatest for 'Espana' at the first two harvests
(> 5 oz), but was similar to 'Astrione' and 'NK 9145' at the third
harvest. Fruit weight dropped 50 to 70% from the first harvest to the
fifth harvest. Cull production was not significantly different among the
entries for each of the first three harvests, but rose from an average of
7% at the first harvest to 29% at the third harvest. Most significant
damage to fruit by worms was evident at the second harvest, when between
11 and 36% of the cull fruit were infested with worms. Virus-like
symptoms among cull fruit were most evident, although not significantly
so, for 'NK 9145' and 'Key Largo' at the first and second harvests.

Summary
Based on yields and fruit characteristics 'Flavor Fry', 'Astrione', and
'Key Largo' were the most superior entries in this trial. They had good
early yields which were sustained through four harvests. They were
typical cubanelles in that the shape, size and coloring of the fruit were
consistent with the cubanelle type. A serious drawback to 'NK 9145' was
its very dark green color and bumpy texture even though its yield was very
comparable to those noted above. 'Espana' and 'Carousel' did not yield
well overall and the fruit shape was unacceptable. 'Carousel' was a small
tapered bell, and 'Espana' was extremely variable in size and shape with
a tendency to be bell shaped.
