摘  要:
用大白菜细胞质雄性不育系CMS22与叶用芥菜可育品系X09-1和X12-1杂交,并以叶用芥菜为轮回亲本连续7代回交,获得了2份不育性稳定的叶用芥菜细胞质雄性不育系。该不育系的不育株率和不育度均为100%,植株形态与轮回亲本相近,有正常结籽能力。花粉母细胞减数分裂末期Ⅰ染色体数目稳定为18条,表明回交核替换已经完成。用转育成的新不育系试配杂交组合,经配合力测定,筛选出4个综合性状优良的杂交种。

摘  要:
A cytoplasmic male sterile line of Chinese cabbage and two male fertile lines of Leaf Mustard were applied to transfer the male sterility. Interspecific crosses followed by 7 generations’backcrosses with Leaf Mustards as recurrent parents were carried out. Two new CMS lines of Leaf Mustards were obtained. It was identified that the CMS lines of leaf mustard possessed equal number of chromosomes with the recurrent parents, and their male sterility were shown as 100% both in the degree and ratio. The morphological traits and the seed set ability of the CMS lines were inclined to the recurrent parents. Four favorite combinations with the CMS as female parent were got through plot trail.
