核不育复等位基因向娃娃菜中转育的研究

Study on Transferring Multiple Allele of GMS to Mini Chinese Cabbage

根据"复等位基因遗传假说",以甲型两用系AB12为不育源(直筒生态型),采用杂交、自交、兄妹交的方法,将核不育基因向娃娃菜可育品系06006中转育,获得了不育株率100%的新核基因雄性不育系,扩大了原有不育系的遗传基础,拓宽了该优良雄性不育基因的应用范围。

Crossing,selfing and sibling were applied to transfer multiple allels of genic male sterility（GMS）from AB12（AB lineⅠ,cylindrical ecotype）to the male fertile line-06006（mini ecotype）in accordance with Multiple Allele Hypothesis of Chinese Cabbage in this paper.As a result,the new genic male sterile lines with 100% sterility were obtained by crossing between the male sterile plants of new AB lines typeⅠand 06006.The genetic basis of the male sterile line was expanded,which widen the applied range of genic male sterile gene.
