摘要
本文概述了玉米雄性不育性的类型、研究结果、应用方法。玉米雄性不育系分为T、S、C三大群,其育性恢保关系、花粉败育特点、细胞质基因组等方面明显不同。利用前景以C群不育系最为广阔,S群不育系次之,T群不育系因专化性感染小斑病菌T小种而停止应用。育性稳定性、恢复性、抗病性是不育性应用中至关重要的问题。
results and utilization of cytoplasmic male sterility in maize were summarized. T, S and C groups,which were different one another among the fertility restoration,the cytological characteristics of pollen abortion and cytogenome, were identified. C group was better than S group in utilizaion,while T group stoped utilizating because of sensitivity to T race. Stable male sterility, fertility restoration and resistance to disease were considered the critical factors.
