70 REPORT ON EXPERIMENT STATIONS, 1953
Agronomic research continues to help meet both domestic and foreign
needs by the releasing of new improved varieties of small grains,
sorghums, cotton, soybeans, peanuts and other oil seeds, potatoes,
sweetpotatoes, tobacco, and other crops. A number of these varieties,
products of the breeding and genetic research programs of the stations
and the Department, are listed and described in the accompanying
table. The special adaptations and uses of several new corn
hybrids are mentioned. Selected examples of current advances in
cultural, tillage, irrigation, fertilizer, and harvesting practices that
are of immediate practical value in crop production, are also given
in the following pages.
New corn hybrids
Michigan 480, a new 105-day (relative maturity) Michigan station
hybrid, surpasses several established hybrids in grain and fodder production
and resistance to stalk and root lodging, is well adapted to
clean mechanical harvest, and has a high shelling percentage. It
may be grown as a medium early hybrid for grain and silage in southern
and south-central Michigan and as a full-season hybrid in northcentral
Michigan, but frost hazard prevents its general adaptation
on muck soils. Ohio W-49, a new yellow hybrid of the Ohio station
(coop. USDA) has stalks and husks that dry fast after kernels fill.
Farmers in central and northern Ohio wanting to harvest with pickers
soon after maturity are expected to like Ohio W-49.
M-1 and M-4, new early maturing, stiff-stalked, high yielding, disease-resistant
corn hybrids developed by the New York (Cornell)
station, are expected to increase grain and silage yields by from 8 to
10 percent. They may yield as high as 100 bushels of dry shelled
corn per acre or 18 tons of nutrient-packed corn silage.
Pa 444, one of 3 new hybrids of the Pennsylvania Station, recommended
for high altitudes and shorter season areas, matures between
Wisconsin 412 and Ohio M 15, both of which it surpasses in root and
stalk and which it outyields by more than 8 bushels per acre. Pa
602 A, another productive hybrid, is recommended for central Pennsylvania
on well-fertilized soils. Pa 807 is a drought-tolerant, longseason
hybrid, for southeastern Pennsylvania, much superior to older
hybrids in tolerance and resistance to borers and aphids.
South Dakota 220, developed by the South Dakota Station, is earlier
than any station hybrid released to date and is adapted to the northern
part of the State. Texas 30, a productive Texas station hybrid,
bears large ears with yellow, dented kernels, resists root lodging and
stalk breakage, and is the most resistant of the yellow Texas hybrids
to earworms and ear rots. It is recommended for all Texas cornraising
areas except the western area.
Purdue 202, a new yellow popcorn hybrid developed by the Indiana
station (coop. USDA), is the first large-kerneled yellow hybrid available
in the early maturity group. It stands well, silks earlier, and has
a lower harvest moisture content than any Purdue hybrids released
previously, and its expansion has averaged 341/.
