广亲和性品种(WCV)与籼、粳稻的杂种F1表现可育。若控制广亲和性的基因遗传简单,则可能作为桥梁基因克服籼粳杂种半不育障碍。本试验研究了以爪哇型广亲和性品种为亲本的F1代(籼 × WCV、粳×WCV)、F2,代[籼 × WCV F2、粳 × WCVF2及粳 ×(籼× WCV)可育株Fd]、三交杂种[(籼
Broad compatibility varieties (WCV) and indica and japonica hybrid F1 performance of fertile. If the genes controlling broad compatibility are genetically simple, they may serve as bridge genes to overcome the semi-sterility disorder of indica-japonica hybrids. In this study, F1 generation (indica × WCV, Japonica × WCV), F2, generation [indica × WCV F2, japonica × WCVF2 and japonica × WCV) fertile lines Fd], three hybrids [(indica
