摘要
60 Coγ射线辐射水稻恢复系获得 4个隐性单基因不等位雄性不育突变体。用雄性不育突变株 可育株杂合体植株作父本 ,与 1 5个种质的同核异质代换系 (作母本 ) ,杂交配组成 60个组合。结果F1代小穗正常可育 ,F2 代分离出数量不等的雄性不育株。未发现雄性不育基因与异源胞质互作表现完全可育的基因型。
Rice restorer lines were treated with 60Co γ-ray and 4 male sterile mutants obtained with the fertility of controlled by 4 non-allelic recessive genes, respectively. Sixty combinations were made by using male sterile plants/fertile plants as male parents, and 15 different cytoplasmic substitution lines of the same cell nucleus as female parents.The result showed that F_1 spikelets were normal and fertile, and different numbers of male sterile plants were segregated in F_2. Complete fertility genotype was not found among interactions between induced male sterile genes and alien-cytoplasms.=
