| Abstract: | Relationship between resistance variation of main hybrid rice varieties, such as Shanyou 63, Gangyou 22 etc., and pathogenicity variation of blast pathogen were systematically monitored and were analyzed in the southeast of Sichuan Province in 1987～2002. The law of resistance breakdown of rice varieties to rice blast were found. And it was of great practical importance to prediction of resistance breakdown of rice varieties to rice blast and application of rice varieties resistant to rice blast. |
