Variety Trials for Sh-2 Type Sweet Corn

J. M. White ..
Assistant Horticulturist 1 ,I .

INTRODUCTION p 19

Genes or hereditary factors determine the sugar contest of the sweet corn
Kernel. The sugar in sweet corn is controlled by the recesA.,s .en ,su. The
relatively recent discovery of the shrunken 2 (sh2) gene, whicd pSroQ64d ., o6 j
or more the amount of sugar found in regular sweet corn, has lead to t e l
development of new types or varieties of sweet corn called "Supersweet."
These varieties retain sugar much longer after harvest and may be desirable
in shipping corn to distant markets.

MATERIALS AND METHODS

This experiment was conducted to test the yield and some plant characteristics
of the new sh2 types of sweet corn. It was a randomized block experiment with
eight replications in Zellwood on Everglades mucky peat and six replications in
Sanford on Leon fine sand. Plot size was 3. 0 feet (Zellwood) and 2. 5 feet
(Sanford) times 25. 0 feet long.

Prior to hand planting two seeds every 8 to 9 inches in Zellwood, 800 lb. /acre
of 5-5-8 fertilizer and a 2% parathion bait for wireworm control at 40 lb. material
per acre were broadcast and disked to incorporate. Plants were hand thinned to
one plant per 8 to 9 inches. In Sanford, 500 lb. /acre of 5-5-8 fertilizer was
broadcast and disked in prior to planting one seed every 8 to 9 inches. Four side
applications of 500 lb. /acre of a 10-4-10-3 fertilizer were made.

A 50-50 mixture of Randox and Vegedex 20 G at the rate of 30 lb. material
per acre was applied to control weeds. Methomyl was used on a daily basis from
silking until harvest for the control of corn earworm.

All varieties were harvested on the same day. Therefore, optimum maturity
for each variety was estimated because some varieties were over mature while
some were immature.

The Zellwood trial was planted on March 27, 1975, and harvested on June 5,
1975. The Sanford trial was planted on April 4, 1975, and harvested on June 11,
1975.

Ears were counted and weighed with husk on. Ear length and width (diameter)
measurements were taken on a random sample of ten husked ears per replication.
Ear tip fill was assigned a value of 5 when completely filled and a value of 1 if
over one inch of the tip was not filled. A value of less than 2.5 would be
questionable for commercial fresh market use.

RESULTS AND DISCUSSION

The results of the Zellwood trial are found in Table 1. Sugar Dots "G"
produced the largest number of ears with 1, 416 dozen ears per acre. It was
also the heaviest producing with 5.8 tons per acre. Sugar Dots "G" ear width
was 1. 9 inches, which is on the large size and may be a disadvantage. E. S, 505
and E.H. 2086 had ear widths of 1.8 and were also considered on the large size
for fresh market.

Florida Sweet had some shank rot on the inside of the husk. E. H. 2086,
E. S. 505, E. S. 449G and E. S. 506 had some shank rot, but it had not developed
inside the husk. Sugar Dots "G", E. S. 507, and E. S. 506 had some lodging, but
was considered light and not a problem. E. H. 2086 had a variable ear tip fill
in the Zellwood trial and a very poor ear tip fill in the Sanford trial.

The results of the Sanford trial are found in Table 2. In the data not
corrected for stand, E. S. 505 produced the largest number of ear with 1, 704
dozen per acre. In the adjusted yield (Table 3), E. S. 449G produced 1, 738
dozen ears per acre while E. S. 505 produced 1, 704. In the leading Zellwood
variety, Sugar Dots "G" had poor ear fill in Sanford and produced only 900
dozen ears per acre (Table 2). Florida Sweet had some green tip on the
ears. E. S. 449H, E. S. 505 and E. S. 507 were harvested one to three days
early in Sanford. Sugar Dots "G" was harvested two or three days late for
optimum maturity. Poor plant stand, due in part to insufficient seed, may
account for the lower yield for E..S. 449G and E. S. 449H.
