Pumpkin/Gourd Variety Trial, Summer 1988
Ivalou Hancik and J. M. White
A replicated pumpkin and gourd variety trial was conducted at
the Central Florida Research & Education Center, Sanford, FL,
during the summer of 1988.
Although current pumpkin production in Florida accounts for
a miniscule percentage of total statewide vegetable production,
there is significant demand for this commodity, as evidenced by the
tonnage of pumpkins shipped to Florida from other areas, to justify
an evaluation of the commercially-available varieties.
Materials and Methods
Twenty-four lines of pumpkin and six lines of gourd were
evaluated for their suitability to Central Florida growing,
Conditions. Pumpkins ranged in size from miniature to very large;
gourds were assorted shapes and sizes. Prior to planting,
dolomitic lime (1 ton/A), 6-6-6 fertilizer (500 lb/A), and furadan
(2 lb a.i./A) were applied to the field.
A pre-emergence application of Command at a rate of 1 lb
a.i./A, was made on July 14, 1988. Seeds were planted by hand in
hill on a Myakka fine sand on July 14. Single-row pumpkin and
gourd plots were 20 ft. wide and 25 and 20 ft. long, respectively.
Approximately 4-5 seeds were planted on hills 2 ft. apart;
seedlings were thinned on July 25 to one hills every 4 ft. with two
plants per hill. The field was drenched with Ridomil (3/8 lb
a.i./A) at planting time.
Sidedress applications of 6-6-6 and 10-4-10 were made during
the first month after planting. 'A weekly disease control program
was initiated which included alternating fungicide (Bravo) and
fungicide/insecticide (Bravo + Pydrin) sprays.
Plants began to flower on August 8. Plots were harvested on
October 12. All fruit was harvested, regardless of maturity.
Pumpkins were weighed, counted, and measured. Gourds were weighed
and counted (Tables 1 & 2).
Results and Discussion
Excessive rainfall (7.51 in.) during the first week of
September made it impossible to apply the weekly fungicide
treatment to the pumpkins/gourds. As a result, a severe disease
problem (especially powdery mildew) began to spread through the"
field. Although some lines possessed moderate disease tolerance,
(Munchkin, Jack-Be-Little, and Large Sorts Gourd Mixture), others
were severely damaged by disease (Spirit and Small Warted Gourd
Mixture). In general, disease pressure significantly reduced
yields (number and size) of pumpkins and gourds, making meaningful
statistical analysis of these results impossible.
The miniature pumpkins and several of the gourd lines produced
large numbers of mature fruit being less adversely affected by
disease pressure than the standard Jack-O-Lantern type pumpkins.
An experimental line of pumpkin, PSX 10295, outyielded all other
entries in the trial and possessed some degree of disease
tolerance; fruit was oblong/oval and pale peach in color (Kentucky
The results of this study re-enforce the importance of strict
disease control for successful pumpkin production in Florida.
Miniature pumpkins and certain gourd lines seemed more suited to
central Florida growing conditions and may be a viable option for
