摘要: [目的] 对杂交稻品种进行稻曲病抗性鉴定,揭示宜香系列水稻品种抗稻曲病原因。[方法] 在雅安和江油地区的水稻病圃,通过稻曲病抗病性鉴定,对不同杂交稻组合稻曲病病情指数进行方差分析及配合力分析。[结果] 研究表明不同地方、不同品种年度间发病情况不同,稻曲病抗性受基因加性与非加性效应共同作用,母本对杂种F1代稻曲病抗性的形成有至关重要的影响。[结论] 通过病情指数配合力分析为选配稻曲病抗性杂交组合提供依据。

Abstract: [Objective] This experiment was conduct to identify resistance of hybrid rice varieties on rice false smut and to reveal the rice false smut resistant of Yixiang varieties in Yaan and Jiangyou areas.[Method] By identification resistance of different hybrid combinations on false smut resistance,ANOVA and combining ability analysis of disease index variance of rice false smut were performed.[Results] The results showed that the incidence differed from geography and breed in years,and genetic additive and non-additive effects work together on smut resistance. Female parent played a leading role on the false smut resistance in F1 hybrids.[Conclusion] Combining ability analysis through disease index provide the basis for selecting the anti-smut hybrids.

Key words: rice false smut, disease index, disease panicle rate, resistance
