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.
