PUMPKIN VARIETY EVALUATION
SUMMER/FALL 1992

D. N. Maynard1

Pumpkins are grown mostly for sale during October and November for decorative
purposes. Statistical data on production in Florida are not available, but it
is estimated that only a few hundred acres are grown in the entire state.
Production from this acreage is not nearly enough to satisfy the demand, hence
considerable tonnage is shipped into the state, primarily from the midwest.

Previous evaluations of pumpkin varieties in Florida were made by.Greene (1974)
in Quincy, Howe and Waters (1983) in Bradenton, Gilreath and Maynard (1986) in
Manatee County and by Elmstrom et al., (1988) in Manatee County and at Leesburg.
A number of new varieties have been released since these trials were conducted.

Because of the potential for increased pumpkin production in Florida, an
evaluation of 18 commercially-available varieties was conducted in the summer and
fall of 1992 on a commercial farm in Manatee County.

MATERIALS AND METHODS
Varieties in this trial (Table 1) were mostly typical Halloween pumpkin
(Cucurbita peoo) types even though fruit size ranged from miniature to large.
Three varieties, 'Big Max', 'Big Moon', and 'Prizewinner', although frequently
grown and used as pumpkins are actually squash (Cucurbita maxima).

This trial was conducted on a commercial farm in Manatee County using practices
employed by the grower for pumpkin production. Beds were formed in early July
by incorporating 200 Ibs 2-18-4 (N-P20 -K2O) per acre and banding 1200 Ibs 10-0-
20 per acre on each shoulder of he bed prior to application of white
polyethylene mulch. The final beds were 8 inches high and 36 inches wide. Beds
were on 13 ft centers with four beds between seepage irrigation/drainage ditches.
Pumpkin seeds were planted through holes punched in the polyethylene at 3 ft in-
row spacing. After thinning, each 30 ft long plot contained 10 plants, and plots
were replicated three times in a randomized block design.

Pumpkins were harvested 8 to 12 October. The miniature and very small-fruited
pumpkins were counted and weighed in bulk and larger fruit were weighed

individually. Five representative fruit from each plot were selected for
measurement with calipers and fruit rind color was assessed by comparison with
recognized standards (RHS Colour Chart). Later, these colors were converted to
a 0 (light yellow) to 5 (dark orange scale) for statistical analysis.

RESULTS AND DISCUSSION

The number of fruit produced per acre ranged from 819 for 'Big Moon' to 22,189
for 'Jack-Be-Little'(Table 2). Fourteen other varieties produced a similar
number of fruit as 'Big Moon', whereas no other variety produced as many fruit
per acre as 'Jack-Be-Little'. The number of fruit produced per plant varied from
0.7 for 'Big Moon' to 19.9 for 'Jack-Be-Little'. Thirteen other varieties had
production per plant similar to that of 'Big Moon' and no other variety produced
as many fruit per plant as 'Jack-Be-Little'. Fruit yield varied from 46 cwt/acre
for 'Oz' to 467 cwt/acre for 'Prizewinner'. Two other entries had yields similar
to 'Oz', and one variety had yields similar to those of 'Prizewinner'. Average
fruit weight varied from 0.3 lb for 'Jack-Be-Little' to 50.4 Ibs for
'Prizewinner'. Two other varieties had average fruit weight similar to 'Jack-Be-
Little'. Eight entries produced fruit that had height:width ratios greater than
one, whereas 10 varieties had fruit with height:width ratios less than one. The
range was 0.60 for 'Jack-Be-Little' to 1.09 for 'Big Moon' and 'Happy Jack'.
Rind color was lightest in 'Big Moon' and 'Jack-Be-Little' and darkest in
'Prizewinner'. Twelve other varieties had rind color similar to that of
'Prizewinner'.

Pumpkin yields in this trial exceeded those obtained in previous trials in
Florida (Elmstrom et al., 1988; Gilreath and Maynard, 1986; Greene, 1974, and
Howe and Waters, 1983). The general pattern of the highest per acre yields being
produced by varieties that produce very large fruit was repeated in this trial.

The distribution of fruit according to weight (Table 3) provides an index of the
tendency of a variety to produce fruit of uniform or variable weight. For
example, 'Jack-Be-Little' fruit were all less than 1 lb and 'Big Max' and
'Prizewinner' fruit were all more than 20.1 Ibs. On the other hand, 'Aspen',
'Big Autumn', 'Happy Jack', and 'October' produced fruit in four of the weight
classes.

Based on the results of this trial, outstanding varieties based on yield and
color in each size class were:

Miniature: Jack-Be-Little
< 1 lb

Small: Baby Pam
1.0-5.0 lb

Medium: Autumn Gold
5.1-10.0 lb Wizard
Spirit
October
Big Autumn
Happy Jack








Large:
10.1-20 lb

Very Large:
> 20 lb


Connecticut Field


Prizewinner
Big Max


For the jack-o-lantern trade, pumpkins weighing at least 8 Ibs and not more than
18 Ibs are preferred. Larger fruit are useful for individual display purposes
and smaller fruit often are used in combination with other pumpkins and fall
decorations. In almost all cases, a bright or deep orange color is preferred to
a light orange or yellow.

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.
