accepted in the Corn Belt and their use continues to expand rapidly
in other areas.
AES 805, a new corn hybrid developed by the Illinois station and
adapted in northern Illinois, has averaged 99 bushels per acre yield
compared with 90 bushels for seven other hybrids. It also excelled in
resistance to lodging, smut, and leaf blight, dropped no ears during
harvest, and the ears were usually free of husks, a desirable attribute
in connection with machine harvesting. AES 702, also developed by
the Illinois station and adapted farther south in the State averaged
83 bushels an acre yield, surpassed eight others in resistance to leaf
blight and lodging, and equaled them in all other characters.
Minhybrid 411 and Minhybrid 412, developed by the Minnesota
station, are resistant to the larvae of the first brood of European corn
borer, and a third AES 610, is borer-tolerant and shows a low percentage
of stalk breakage from borer damage. Minhybrids 508 and
409, new productive hybrids excelling in standing ability, resemble
older recommended hybrids in their reaction to borer.
Michigan 250, a Michigan station hybrid with 85-day maturity,
adapted to corn areas in northern and extreme east central Michigan,
is a good grain producer. Michigan 350, which ripens in about 90
days, is adapted to northern and north central Michigan and has also
made exceptional grain yields on muck soils in south central and southern
Michigan. K1830, a yellow hybrid developed by the Kansas station
(coop. USDA), and found superior to K1585, is recommended
for southeast and south central Kansas.
Okla. 301, bred by the Oklahoma station for Oklahoma conditions,
outyields the average of currently recommended hybrids by 10 percent,
has a tight husk which protects it against ear worms, and stands
well. Texas 15-W, a white hybrid developed by the Texas station,
outyields other white hybrids now sold and stands well. It is adapted
to the Blackland Prairie, where it may replace Texas 11-W. Dixie 82,
a high-yielding hybrid with good roots and stalks, developed by the
Department and the North Carolina station in the southern cooperative
corn improvement program, matures a week earlier than Dixie 18
and ripens slightly later than hybrid N. C. 27, both of which it has
VPI 802 and VPI 645, hybrids developed by the Virginia station,
are resistant to stalk rot and leaf blights and to lodging. VPI 802
outyields and matures a little earlier than U. S. 262 and U. S. 357.
and VPI 645 is a little later than U. S. 13. VPI 802 is recommended
for eastern Virginia, and VPI 645 for sections west of the Blue Ridge
and for northern Piedmont.
Connecticut 103, an inbred containing as much sugar in its stalk
juice as sugarcane, is one of the best ensilage inbreds developed by the
Connecticut Agricultural Experiment station. It has strong stalks
and resistance to aphids, leaf blight, and stalk rot, and has been used
extensively in the Midwest in double-cross hybrids. Connecticut 845,
a hybrid that contains four sugar inbreds of this station and is now
in commercial production, stands well, resists stalk rots and leaf diseases,
and produces good yields of grain and silage.
