본실험은 1980년과 1982년에 한국에 분포하고 있는 보리흰가루병균의 race를 동정하기 위하여 Cherewick의 6개판별품종 Black Hulless, Chevron, Goldfoil, Heil Hanna, 3, Nepal, 및Peruvian을 사용하여 하였다. 1. 1980년과 1982년 93개지역에서 수집된 보리흰가루병균은 9가지 race 3,8,11,19, J13, K1A, K1B, K2, 및 K3으로 동정되었으며 이들 중 K1A, K1B, K2, K3은 한국에서 최초로 동정되었다. 2. 우리나라에서 동정된 race A1A, K1B, K2, K3는 주로 전남과 경남지역에서 수집되었고 race 9은 전북 부안에서만 분리되었다. 3. 일본에서 동정된 race J13은 남부지역에서 분리되었으며 전체분리균주의 를 차지했다.

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 of total isolated races, mostly being isolated in southern region of Korea.
