CABBAGE STRAIN TRIALS AT HASTINGS, FLORIDA 1967-1968
J. R. Shumaker, Asst. Horticulturist

METHODS:

Fifty-five cabbage strains (varieties and experimental lines) were evaluated
primarily for fresh market adaptability to the Hastings area during the 1967-
1968 growing season. Twenty-eight of these strains were incorporated into a
randomized block design consisting of four replications (Table 1). The re-
maining 27 strains were lined out in individual observation plots (Table 2).
Plot size for both trials was 25 row feet. Hot-water treated seed of each
strain was sown October 4th and plants were transplanted November 17th.
Plants were spaced 10 inches apart within a row with 40 inches between rows.
Recommended cultural and insect and disease control practices were followed
during the growing season. Harvesting began February 2nd and was conducted,
as maturity demanded, until conclusion on April 15th.

RESULTS:

Tables 1 and 2 summarize each strain as to its (1) source, (2) number of days
from transplanting to first harvest, (3) per cent of total yield at first har-
vest, (4) total yield and (5) average weight per head. Nine horticultural
characteristics for each strain are summarized in Table 3. Either a descrip-
tion or a scale of 0 5 was used in evaluating each character. A rating of
5 was most desirable. For comparison the most popular varieties grown in the
Hastings area are King Cole, Market Topper, Market Prize (hybrid varieties)
and Greenback (open-pollinated variety). In addition to these varieties
other varieties have performed well the last two seasons and apparently have
seed available. They are now recommended for trial in commercial planting
and are as follows:

1. Early to medium maturity

a. Rounded to semi-round heads
Headstart, Kleen Cut, Little Rock and Superette
b. Semi-flat to flattened heads
Hybrid 21 and Rio Verda ------------ I

2. Medium-late to late maturity

a. Rounded to semi-round heads OCT 25 1S53
Resistant Danish
b. Semi-flat to flattened heads -
Saf-Gard (Hybrid 18) L.-.. : c ,-.

Several other strains having their first entry in the trials performed well.
They will be further evaluated during the 1968-1969 season for fresh market
adaptability.










MECHANICAL HARVESTER ADAPTABILITY:


Since a strain's uniform maturity is essential to the success of a once-
over mechanical harvesting operation, evaluation of its adaptability for
this characteristic (Table 3) was rated by.a scheme consisting of the follow-
ing components: (1) percentage of total yield at first harvest, 40%; (2)
uniformity of head shape and size, 20%; (3) field-holding quality, 20%; and
(4) plant type as related to harvester requirements, 20%. Hybrid strains
generally continued to show higher degrees of uniformity for the first two
components than did the open-pollinated ones. Inasmuch as the first harvest
for each strain was determined at the time when one or two heads burst or
split, per cent of total yield at first harvest is, in part, dependent on
a strain's field-holding quality. Soil moisture and temperature relation-
ships just prior to market maturity favored field-holding quality of the late
maturing strains over the early maturing ones. Because of this, more valid
comparisons can be made between strains within the same maturity group than
between those of different maturity groups. Therefore, the most desirable
ratings obtained for harvester adaptability were 3.5, 4.0 and 4.5 for early,
medium and late-maturing strains, respectively.
