Breeding corn hybrids for smut resistance
1942
Stringfield, G.H. | Bowman, D.H.
Smut counts made in 48 corn performance experiments showed that about three-fourths of the hybrid entries carried less smut infection than did the open-pollinated varieties in the same experiments. Twelve inbred lines appear to be more or less resistant to corn smut. Hybrids in which half or more of the parentage consisted of these resistance inbred lines showed less than a third as much smut as did the open-pollinated varieties. It is shown that hybrids have been developed that combine a high degree of smut resistance with other desirable agronomic characters. Such hybrids are being grown extensively. The use of these and similar hybrids in other states constitutes the first significant advance in the control of corn smut.
