Bunt reaction of hard red winter wheats in 1938-42
1945
Quisenberry, K.S. | Rodenhiser, H.A. | Johnston, C.O.
A large number of varieties and strains of hard red winter wheat have been tested for bunt reaction at several stations in the Great Plains and at Kearneysville, W. Va.; Beltsville, Md; and Logan, Utah. The inoculum used was a composite of collections of Tilletia foetida and T. caries obtained from fields selected at random throughout the state in which the test or tests were made. No variety was free from bunt in all tests, but a number showed considerable resistance. Selections from such crosses as Hope X Turkey 1069, H44 X Minturki, Oro X Tenmarq, Martin X Tenmarq, and Blackhull X Oro had a rather high degree of resistance. Since only bulk inoculum was used, these tests should be considered as preliminary. The more resistant varieties are being tested to known races. When tested with the dwarf bunt organism at Logan, Utah, four strains were as resistant as Relief and eight as resistant as Hussar. Most of these wheats had Hussar, Martin, or Ridit as one parent.
