Abstract

Two methods were used to identify the teleomorph of Oidium lini. In the first method, antiserum of flax infected with O. lini interacted against antigens of healthy plants (flax, okra, sunflower, tobacco, peas, alfalfa, and cocklebur). In the  second method, antiserum of flax infected with O. lini interacted against antigens of the same hosts infected with powdery mildew. Cluster analysis of the antigenic patterns, obtained in each method, indicates that Erysiphe polygoni is the teleomorph of O. lini.
