| 摘 要： | 水稻颖花突变体是开展鉴定和克隆水稻花器官发育基因研究的重要材料,在水稻重组自交系构建过程中,发现一个水稻花器官数目突变体,暂命名为fon6(floral organ number).首先对突变体的花器官性状进行鉴定,然后利用F2群体进行遗传分析和基因定位.该突变体的特征为浆片颖壳化,内外稃和雌蕊增多,雄蕊减少并外露,雌...

| Abstract: | The rice spikelet mutant is just the most important material for the identification and cloning of floral organ development genes in rice. A rice floral organ number mutant was found in development of a recombinant inbred lines (RIL) population, and temporarily named as fon6 (floral organ number). The phenotypic traits of mutant floral organ were identified, and F2 segregation populations were used to precede genetic analysis and gene-mapping. The mutant was characterized with the phenotype of glumes-like l... |
