HORTICULTURAL TRIALS WITH SwEET CORN HYBRIDS, SPRING 1954


Eil A. Wolf*




Sweet corn growers in the Everglades area are continually seeking improved
hybrids which will produce higher yields and/or a higher quality product or which
will possess more desirable plant characteristics which make them easier to grow.
During the spring of 1954, one hundred sweet corn hybrids, including many experi-
mental hybrids from seedsmen and other experiment stations, were compared with Gold
Rush, loana and Golden Security--the three hybrids most commonly grown in the area.
Planting was carried out on February 18 and 19. Fertilization was in accordance
with station recommendations,

Leaf blight lesions caused by Helminthosporium turcicum Pass. were first noted
when the plants were about one month old. protective spraying with zineb fungi-
cide (Parzate) was started at that time and 8 applications in all were made, being
discontinued 12 days before harvesting of the earliest hybrids. Development of the
blight was not checked because of frequent rains, poor timing, inadequate coverage,
and perhaps insufficient number of applications. At harvest time, the disease was
quite severe on mary of the hybrids, as will be noted in column 4 in the three ao-
companying tables* However, because of late appearance of the disease, yields did
not appear to be much affected.

Twenty.one hybrids, listed in Table 1, were grown in the regular replicated
yield trials. There were four replications of 201 plots each containing two rows
three feet apart and plants thinned to 12" apart in the row. The more promising
hybrids from the 1953 trials were included in this trial. As shown in Table 1,
experimental hybrid #9756-37 from Crookham Company, Paymaster, and Table Gracer all
yielded, as well as Gold Rush and Golden Security and showed resistance to the H,
turcicum organism which had been observed previously, however, each showed cerTain
ear characteristics which may prevent their acceptance by growers. The shuck barely
extended beyond the end of some of the ears of Table Gracer, the most resistant hy-
brid in the trials. Paymaster has been reported elsewhere to have some resistance
to the corn earworm. It was highly productive but it produced a short, thick ear
with broad kernels even larger than Illinois Golden #10. In view of the trend of
preference for ears which an bepacked i4i dozen in the wire bound box, it is question-
able as to whether the large ear and kernel of Paymaster will meet with acceptance.
Plants of experimental #9756-37 had a very desirable growth habit and possessed some
disease resistance. Ears of this hybrid tended to be a little short, but they ap.
peared to ripen well to the tips and produce a very attractive ear with small kernels.
There were no significant differences in yields between the four loana hybrids ob-
tained from different sources, however, Golden Security significantly outyielded
the Service Seed Company strain*

Seventy-five hybrids were grown in duplicate and four in single observational
plots for comparison with the standard hybrids. Plots were 20 feet long with two
rows three feet apart and plants thinned to 12 inches apart in the row. Six experi-
mental hybrids from Crookham Company showing fair to good resistance to H. turcicum
were outstanding. This group of hybrids has a common parent which has b1en found iTr
previous tests at this Station to be well adapted to the area and highly resistant
to this disease. Of this group of six, 22768-14 was the most resistant and shows
very good possibilities* Other hybrids which were considered to show promise were
Topyield and Melocross from Michael Leonard, Ferry Morse #72, Northrup King #526,
18491 emd 17112 from W. A. Huelson, University of Illinois, and KVFl-.100 from Cor:J.
