CABBAGE, Brassica oleracea var. capitata Linn.

VARIETY AND STRAIN TEST


James C. Hoffnan


April 1948








CABBAGE VARIETY A~D STRAIN TEST


19 4 8

James C. Hoffman

The test consists of 36 seed stocks planted to seedbeds November 11, 19?h7 The
seedbeds ware of the open type and were condi!iored 10 days before planting Fer.il-.
iLer was applied broadcast to the seedbed area at the rate of 600 po-ur.ds .of 0-16 ,.i6,
30 pouindv manganese u.fate, 30 pounds copper sulfate, 20 px-nds .inc sulfate and 10
poitlnd of borax per acre

Downy mildew appeared on the small seedlings and was controlled by 3 applications
per week with an additional application after each rain of Tetrachlorobenzoqui.none
goneza''y designated by the trade name of Spergon. The rate of application was 4
pcr:uds uer 100 gallons of water and approximately 1.25 gallons of the material spray-
ed on each 100 square feet.

The plots were located on well mature sawgrass peat with a pH of 6.10. Fertil-
izer was applied at the time of transplanting in 2 bands 3 inches to eaoh side of
the plants and 2 inches in depth, the rate of application being the same as for the
seedbeds,

Transplanting was completed December 24. The rows were spaced 28 inches apart
and 2 rows 48 inches apart were established for spray equipment traveling. These
4U-incb rows were spaced every hth row; there was one 28-inch middle between the two
4i--inch middles which the tractor and spray equipment straddled. The plants were
transplanted at 12-inch spacing in the row.

Each variety and strain numbered 1 14 inclusive was replicated in single riws
30 feet in length 5 times and randomized in 2 complete block designs. Number l:b
appeared in 1 replicated design. Plants were grown at Hastings for the second series
of replicated blocks. The yield data for the Hastings grown plants are recorded in
Table 1, numbered columns 13, 14 and 15. Numbers 16 36 inclusive as recorded in
Table 2 were observational plots transplanted to 2 blocks, the second block being
Hastings grown plants. The data in Table 2 are averages of the 2 observational plots
of each variety and strain,

Alternaria leaf-spot, Alternaria brassicae (Berk.) Sacc., was controlled by
weekly applications of zinc dimethyl-dithiocarbamate (white Karbam) at the rate of 2
pounds per 100 gallons of water and applied at the rate of 125 gallons per acre"
Cabbage aphid, Brevicoryne brassicae Linnaeus, appeared in 3 cycles of inporta.ce
axcd wore controlled by single applications of gamma isomer of Benzene Hexachloz rido
(isvtcx) at the rate of 1 pound of 25 percent material to 100 gallons cf wat'?- and
applied at approximately 125 gallons per acre. To control chewing insects I quarts
of .7: percent rDT was added per 100 gallons of spray material as described tbovec
The D'T unly necessary in every 3rd application. All of these spray matei' al.;
arc :c'-atible and may be applied in a single application, or separately when needed
for the insect or disease present.

All varieties and strains were harvested by 2 cuttings, the number of days from
transplanting to the first harvest is listed in Tables 1 and 2 numbered column 2c

The temperature for the growing season after transplanting averaged 7422C0F. for
the period from 6:00 A. M. to 6:00 P. a., and 62.70 F. for the period from 6500 PX
to 6:00 A, Me or a general average temperature of 68.$ F. for the cabbage gro7"rin~
season, The water table was held at approximately 28 inches during the season.

All the tests grew extremely well with the exception of series 2 which was de-
layed in growth immediately after transplanting due to Bacterial soft-rot, Bacillus
carotovor's Jones. This disease apparently developed during shipment from Hfast' s.
The reduic"on in yields of series 2 when compared to series 1 was due to the Bacter-
ial soft-rot. Black-rot, Bacterium campestre (Pammel) EFS. usually causes much des-
truction to cabbage in the Belle Glade area, however, very little injury occurred on
those seed stocks, with the exception of number 28.

The data as presented definitely indicates the possibility of producing very
heavy yields on the organic soils of the Everglades. Factors other than yield are
often very important. Solidity is a characteristic that is most important when pro-
ducing cabbage for shipment to a northern market. Those progeny that have been
classed 4 and 5, or very solid and extremely solid respectively, are considered ex-
cellent stocks for shipment. The variety cabbage "B" is a very solid type somewhat
similar to Glory of Enkhuizen but with a smaller head. Copenhagen Market 86, Round
Dutch and Golden Acre arc early types that would be greatly improved if they could
be classified as very solid or extremely solid.

Two breeding stocks listed as 34 and 35 are very outstanding progeny that are
classed as very solid. There is a possibility of selecting an early cabbage with
very solid heads from these stocks that will be an improvement over the present
early types. These progeny must be fixed for type before introduced as a variety,
