Title: Race identification and pathogenicity test of the blast fungus causing the resistance breakdown of hybrid rice Tianyou 998
Abstract: 11 single blast spore cultivated strains were isolated from a hybrid rice Tian You 998.Race identification of these strains were conducted based on the Chinese blast differentials.The result indicated that all the isolated strains were belong to the race of ZB3.Three strains of TY1,TY4 and TY21 were used for the pathogenicity test.Of 44 tested rice varieties and combinations,11 varieties and combinations,which including TianYou998,BoYou998,BoYou903 and so on,appeared highly susceptible to the tested pathogen.7 of varieties and combinations,which including IIyou3550,Shanyou3550,Kyou451,Jinyou253,Liangyou326,Texianzhan13,Yesizhan,showed moderate susceptible,26 of varieties and combinations were resistant to the tested pathogen,they are Youyou122,Longyou665,Shanyou46,Yueza763,Jingxian89,Yuexiangzhan,Fengsizhan,Baixiangzhan and so on.
