This report summarizes the evaluations of 15 cultivars/breeding lines of zucchini
squash. Entries were evaluated for adaptability to central Florida's spring production
conditions. The field was prepared (fertilized and pesticide applied) on March 9, 1994, as per
guidelines suggested in the Extension Service Control Guide; raised beds were formed and
covered with black plastic mulch. Squash seeds were planted by hand in hills (2-3 seeds/hill)
24" apart in 25' long plots on March 11, 1994. A randomized complete block design was used
with four replications per entry. Plots were thinned to one plant per hill on March 23, 1994.
Harvesting began on April 18, 1994, and concluded with the twelfth harvest on May
24, 1994. Yield data and other characteristics rated in this trial are found in Table 1; weather
data are recorded in Table 2.
Summary
Total marketable yield, expressed as 42-lb bushels/acre, ranged from 604-988. Early
(first three harvests) marketable yield ranged from 57-155 bushels/acre. Both Spineless Beauty
and Sunre 9718 were top yielding cultivars in the 1993 as well as the 1994 trial.
Several entries (ZS5, PSR 35691, ZS4, and ZS2) produced poorly-shaped fruit; fruits
were bulbous at the stem end, tapering to a point at the blossom end. XPG 826 produced
both green fruit and golden fruit. -
This report is not intended to recommend one variety over another, but rather is meant
as a general guideline for variety selection. Different field locations, planting dates, and
cultural practices may alter the performance of these squash lines; growers should be mindful
of this variability when selecting a new variety, and small test areas of new varieties may be
advisable.
