CABBAGE VARIETY TRIALS AT HASTINGS, FLORIDA iTf-971
J. R. Shumaker, Asst. Horticulturist

METHODS:

Twenty-four cabbage varieties were evaluated for fresh market adaptability
to the Hastings area during the 1970-71 growing season (Table 1). Hot water-
treated seed of each variety was sown October 12, and plants were transplanted
November 30. Recommended area cultural and management practices were followed.
Harvesting began on February 22 and was conducted as maturity demanded until
conclusion on April 12. A rating of 1 (poor) to 5 (desirable) was used in
evaluating internal head quality and uniformity of type. Because of the
effect of external head quality on market grades of cabbage, the following
classification was used: 1.0 to 2.4, unmarketable; 2.5 to 3.9, marketable with
wrapper and top head leaves removed; and 4.0 to 5.0 marketable as harvested.

CONDITIONS:

During the early part of the growing season above average temperatures and
below average rainfalls were recorded. However, unseasonably cold and wet
conditions prevailed during the winter and early spring. On January 21 a hard
freeze, 170 F, was quickly followed with a high temperature for that date of
610 F. Severe reduction in quality and severe to moderate reductions in yields
and size were observed and attributed both to this freeze and to the persis-
tently low temperatures during the remaining season.

RESULTS:

Maturity, yield, quality and uniformity of the trials are summarized in Table 1.
The yield differences between varieties ranged from 299 cwt/A (Rio Verde) to
137 cwt/A (Kleen Cut) which was partly due to cold weather. However, the
greatest effect of the cold was a reduction in quality which was associated
more with some varieties than others. All of the early maturing varieties
(84 days from transplanting to first harvest) were generally considered not
marketable. Variable yields and qualities were observed among the medium
maturing (90 days) varieties. Market Prize, standard variety to this area,
was superior in yield and external-internal head quality to others in this
class. All of the medium late to late maturing (99 and 106 days) varieties
produced heads of a marketable grade and yields over 200 cwt/A. Little Rock
produced the best external-internal head quality-uniformity combination along
with moderate yields. Great Dane and Greenback both produced good yield-
quality combinations.

i/ Results based on yield from 25-foot row plots replicated 4 times. Within and between row plant spacings
were 12 and 40 inches respectively.
2/ Seed source: A Asgrow (Kilgore); FM Ferry Morse; JH Joseph Harris; NK Northrup King; TS T.
Sakata (Herbst Bros.); and K Keystone.
3/ External quality associated with direct and indirect effects of freeze damage. Ratings: 1.0-2.4 unmar-
ketable; 2.5-3.9 marketable grade with wrapper and top leaves removed; and 4.0-5.0 marketable as
harvested.
4/ Internal quality associated with core size, head compositions, etc. 1 = poor and 5 = desirable.
5/ Uniformity associated with inbreds and general off-types in each population. 1 = poor and 5 = desirable.
