Abstract:

Yunnan Province of China, a cradle of Asian cultivated rice, abounds in germplasm of both rice and rice blast fungus (Magnaporthe grisea). Many field races on Japanese differential rice varieties, and some field isolates from upland rice, can form the sexual stage under laboratory conditions (Li et al 1993).
