Studies of Compatibility in Australian Isolates of Bipolaris Sorokiniana

Abstract

Australian and Canadian isolates of B. 80rokiniana were used for studies on compatibility and perithecial development. Australian and Canadian isolates belonged to the same two compatibility groups, a and A. When two isolates, one from each compatibility group, were paired, perithecia (Cochliobolu8 sativus) were formed. Both groups occurred in close association at a number of localities in Victoria. Of the 16 Australian isolates collected at random, 8 were of group a and 8 of group A.
