摘要
利用回交替换的方法将大白菜的雄性不育核基因转到异源胞质雄性不育基因的大白菜中去 ,育成了不育率 10 0 %的大白菜核质互作型雄性不育系 98- 2 ,具有核不育基因的雄性不育两用系 10 1便是它的保持系。 98- 2不育系具有生长发育正常、抗病、农艺性状优、配合力好等特点。通过组合配制试验 ,选出了优良组合 98- 2× S- 3。
Chinese cabbage male sterile line 98\|2 with nucleo\|cytoplasmic interactive type was obtained by the methods of backcross and substitution,which nuclear genes with male sterile in Chinese cabbage 101 were transfered into the Chinese cabbage with allogenic cytoplasmic male sterile genes The rate of male\|sterility of Chinese cabbage 98\|2 reached one hundred percentage Its maintainer line was Chinese cabbage 101 of male sterile AB line.98\|2 was noted for normal growing,disease resistant,well agronomy characters and combining ability The excellent hybridized combination of 98 2×S 3 was obtained and demonstracted and spreaded
