Abstract

Physiologic races of Erysiphe graminis f. sp. hordei were isolated from diseased barley plants collected from 93 locations in Korea, 1980 and 1982. Nine races, 3,8,11,19, J13, K1A, K1B, K2, and K3, were identified by using Cherewick's differential plants. Among them, races K1A, K1B, K 2, and K 3 were firstly recorded by authors in Korea. These races were mainly collected from Jeonnam and Gyeongnam province, whereas race 8 was isolated only in Buan, Jeonbug province. On the other hand, race J 13 previously reported in Japan was prevalent as $36.6\%$ of total isolated races, mostly being isolated in southern region of Korea.
