摘    要:运用陆地棉显性无腺体系与2个有腺体系杂交,不去雄人工辅助授粉其真杂交种率为52.4%,与不育系授粉,其真杂种率为99.3%;配制的组合均有不同程度增产,而且纤维品质基本符合育种攻关要求;显性无腺体性状.棉花一出苗,通过下胚轴,即可识别,结合棉花育苗移栽和间苗的特点,淘汰假杂种的工作易于进行;表明了显性无腺体性状是一个优良的指示性状,可以利用。

关 键 词:显性无腺体  陆地棉  杂种优势  指示性状

Abstract:The average cross-pollination rate produced by crossing between two glanded varieties and dominant glandless line and MS5MS6 by supplementary pollination without emasculation was 52. 4 %, and 99. 3 %, and some combinations had promising yleld and fiber quality. so it was suggested that the dominant glandlessness be a desirable marker with distinctness and easy identification by hypocotyl tralt at the seedings stage for easily removing pseudo -hybrid seedlings in the process of transplanting and thinning of the hybrid progeny.
Keywords:Dominant glandless trait  Upland cotton (G. hirsutum L. )  Heterosis  Marker trait
