利用两系杂交种转育不育系过程中,对F_1、F_2及兄妹交1～4代进行育性观察,验证了S_(45)AB和117A不育基因在新不育系中,仍稳定以两对重叠隐性基因控制不育性,并探索了不育系转育方法。
Fertility observation of F_1, F_2 and sibling 1 to 4 generations of male sterile lines using two-line hybrids showed that the sterility of S_ (45) AB and 117A were still stable in new CMS lines Two overlapping pairs of recessive genes were used to control sterility and the methods of CMS breeding were explored.
