【摘要】 对湖北省14个大面积推广的主栽品种的抗稻瘟病性进行了田间自然诱发鉴定。结果表明,对叶稻瘟,除Ⅱ优725、扬两优6号、金优725表现为中抗外,其余11个品种均表现为抗到高抗;对穗颈瘟,除丰两优1号及扬两优6号表现为感病外,其余12个品种均表现为抗到高抗;品种对叶稻瘟与穗颈瘟之间的抗病性没有明显的对应性。更多还原

【Abstract】 The primary experiments of resistance to Ustilaginoidea virens for 14 rice varieties planted extensively in Hubei province were carried out under the condition of nature induce.The trial results showed that the resistances of these varieties were from(R) to high resistance(HR) to leaf blast except Ⅱyou 725,Yangliangyou NO.6 and Jinyou 725 showed moderate resistance(MR) within section periods.Fengliangyou No.1 and Yangliangyou No.6 showed susceptibility(S) to panicle blast,and other varieties showed from R to HR to panicle blast.The resistances of varieties against leaf blast and panicle blast did not clearly correspond.更多还原
