PUMPKIN CULTIGEN EVALUATION
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, by Elmstrom et al., (1988) in Manatee County and at Leesburg, and
by Maynard (1992) in Manatee County. 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 40 commercially-available varieties and six advanced experimental
lines was conducted in the summer and fall of 1993 on a commercial farm in
Materials and Methods
Entries in this trial (Table 1) were mostly typical Halloween pumpkin (Cucurbita
peDo) types even though fruit size ranged from miniature to very large.
Six varieties; 'Big Max', 'Big Moon', 'Cinderella', 'Prizewinner', 'Rouge Vif
D'Etampes', and 'Snowball', although frequently grown and used as pumpkins, are
actually squash (Cucurbita maxima). 'Buckskin' appeared to be still another
species (Cucurbita moschata).
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-P Os-K20) per acre and banding 1200 Ibs 10-0-
20 per acre on each shoulder of the ed prior to application of white on black
polyethylene mulch. The final beds were 8 inches high and 36 inches wide and
were on 13 ft centers. On 21-22 July, pumpkin seeds were planted through holes

punched in the polyethylene mulch at 2 ft in-row spacing for short-vined
varieties 'Baby Bear', 'Baby Boo', 'Baby Pam', 'Jack-Be-Little', 'Jack-Be-
Quick', 'Little Lantern', 'Munchkin', 'Oz', and 'Sweetie Pie'- and 3 ft in-row
spacing for all other entries. Because of space limitations, five plant plots
were used for all of the experimental entries, 'Buckskin', 'Cinderella', 'Rouge
Vif D'Etampes', 'Spirit', and 'Trick or Treat'; ten plant plots were used for all
of the other varieties. Each plot was replicated three times in a randomized
block design. Yields were converted to a per acre basis prior to statistical
analysis to correct for different plot sizes.
Pumpkins were harvested 6 to 20 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 484 for 'Thomas Halloween' to
18,093 for 'Baby Boo' (Table 2). Thirty-four other entries produced a similar
number of fruit as 'Thomas Halloween', whereas only 'Jack-Be-Little' and 'Jack-
Be-Quick' produced as many fruit as 'Baby Boo'. The number of fruit produced per
plant varied from 0.4 for 'Thomas Halloween' to 10.8 for 'Baby Boo' and 'Jack-Be-
Little'. Thirty-three other entries had fruit production per plant similar to
that of 'Thomas Halloween', whereas 'Jack-Be-Quick' and PUXP 2001 produced as
many fruit per plant as 'Baby Boo' and 'Jack-Be-Little'. Fruit yield varied from
37.1 cwt/acre for 'Oz' to 279.7 cwt/acre for 'Prizewinner'. Thirty-two other
entries had yields similar to those of 'Oz', whereas only 'Cinderella' yielded
as well as 'Prizewinner'. Average fruit weight ranged from 0.2 lb for 'Baby Boo'
to 35.3 lb for 'Prizewinner'. Fourteen other entries had average fruit weight
similar to that of 'Baby Boo', whereas only 'Big Moon' and 'Atlantic Giant' were
as heavy as 'Prizewinner'. Eighteen entries had fruit with height:width ratios
of 1 or greater, whereas 28 entries produced fruit with height:width ratios less
than 1. The range was 0.53 for 'Rouge Vif D'Etampes' to 1.32 for 'October'.
Rind color was lightest in 'Atlantic Giant', 'Big Moon', and 'Jack-Be-Quick' and
darkest in 'Baby Pam', HMX 2690, 'Howden', and JSS9032F1 in the yellow/orange
rind entries. Six other entries had similar light color and 22 other entries had
similar dark rind color. 'Baby Boo' and 'Snowball' had white rinds and
'Buckskin' had a buff colored rind.
Pumpkin yields in this trial are typical of those obtained in most previous
trials in Florida (Elmstrom et al., 1988; Gilreath and Maynard, 1986; Greene,
1974, and Howe and Waters, 1983) but lower than those obtained at this location
in 1992 (Maynard, 1992). The general pattern of the highest per acre yields
being produced by entries that produce very large fruit and the largest number
of fruit being produced by entries that produce miniature fruit was repeated in
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 'Baby Boo', HMX 2692, 'Jack-Be-Little', 'Jack-Be-Quick', 'Munchkin', PUXP
2001, PUXP 2003, and 'Sweetie Pie' fruit were all less than 1 lb and HMX 2690,
'Oz', and 'Spookie' fruit were all 1.1 to 5 lb each. On the other hand,
'Connecticut Field', 'Jackpot', and 'Jumpin Jack' plants produced fruit in five
of the weight classes.
Pumpkins of any size and shape are saleable for decorative purposes. For the
jack-o-lantern trade, however, 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.
Outstanding entries based on productivity, rind color, and suitability for the
decorative market in each size class were:
< 1 lb

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 obir-ttiX\.: 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
The Center's primary mission is to develop new
and t ,Ij., Ilr existing knowledge and technology, and
to disseminate new scientific knowledge in Florida, so
that Ilt i 11l1.t remains I H, n, 11.-1t and economically
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.
