【摘要】 以白菜细胞核雄性不育株为母本,以早熟四九菜心为父本,采用杂交转育方法,转育成具有100%不育率、100%不育度的菜薹雄性不育材料。研究发现菜薹的基因型分布比较单一,大多数为MsfMsf。因此,菜薹保持系不能从自然群体中找到,只能通过杂交重组获得。更多还原

【Abstract】 Using Chinese cabbage with GMS as female parent and 49 Caixin as male parent.The hybrid has 100 % sterile rate,100 % sterility.The research discovered the major gene of tsai-tai is MsfMsf.Therefore,the tsai-tai maintainer line can’t be found from the natural population,it can only be obtained through the hybrid.更多还原
