摘　　要：为了研究亚洲栽培稻与非洲栽培稻种间杂种不育的遗传基础 ,以亚洲栽培稻品种 WAB5 6 - 10 4为测验种与来自种间回交组合 WAB5 6 - 10 4 / CG14 / / WAB5 6 - 10 4 / / / WAB5 6 - 10 4的 14个种间近等基因系测交 ,对亲本及杂种的花粉及小穗育性研究表明 ,这 14个近等基因系带有来自非洲栽培稻品种 CG14的 3个互不等位的配子消除位点和 2个互不等位的花粉不育基因位点 ,其中至少有In order to study genetic base of hybrid sterility of interspecific hybrid between Oryza sativa and O. glaberrima, test crosses were made among Asian cultivated rice cultivar WAB56 104 and its 14 near isogenic lines derived from interspecific BC 2 cross WAB56 104/CG14//WAB56 104///WAB56 104. Investigation of pollen and spikelet fertility of parents and hybrids indicated that there were three non allelic gamete eliminator loci and two pollen killer loci derived from O. glaberrima parent CG14 among the near isogenic lines, and at least two gamete eliminator loci are not reported before.
