The physiologic specialization of erysiphe graminis f sp tritici in wheat in czechoslovakia as examined in 1969 and 1970

A review is given on the occurrence of physiologic races of powdery mildew (E. graminis f. sp. tritici) in wheat in Czechoslovakia. The races and their frequency in 1969 and 1970 are given. The spectrum of physiologic races has been increased to 22 races altogether; in 1970 race 3 was the most frequent.
