Abstract:

为揭示总不育小穗数、基部和顶部不育小穗数的遗传特点,利用2个相关重组自交系群体,结合4个环境的表型数据和QTL检测结果,对其进行了分析。2个群体表型数据相关性分析和通径分析结果一致表明,顶部不育小穗是引起总不育小穗数的主要因素,这一结果与前人研究结果相反。环境间表型数据相关性分析结果表明,3个性状受环境影响均较大,其中复合性状总不育小穗数由于受其构成因素基部和顶部不育小穗数的双重影响而表现受环境影响最大,顶部不育小穗数次之。QTL检测结果表明:影响总不育小穗数的遗传因素并非是其构成因素遗传因子的简单累加,总不育小穗数、基部和顶部不育小穗数3个性状在QTL水平关系复杂,既在3个性状间或两两性状间检测到共同QTL,也分别检测到单一性状的特异QTL。顶部不育小穗数与总不育小穗数之间存在显著遗传相关性和较多的共同QTL。为小麦不育小穗性状的遗传改良和小麦生产中栽培措施的合理运用提供了参考依据。
