AMAJOR problem in the wheat-improvement program of the Pacific Northwest is the production of bunt-resistant varieties suitable for commercial use. This problem would be relatively simple were it not for the continued appearance of previously unknown physiologic races of bunt. Oro (C. I. 82~.o)3 and Turkey-Florence (C. I. ~oo8o) are highly resistant to the other known races but are very susceptible to races L-8 and T-~ ~, respectively, and both are slightly susceptible to T-8. 4 A cross of these two varieties of wheat might be expected to produce some segregates resistant to all the races of bunt.
