皖9015是安徽省农科院作物研究所发现并育成的一个新型光敏感型雄性不育系。该材料在合肥地区(N31°51°)短日低温条件下表现为全不育,在长日温暖条件下表现正常可育。在小麦正常发育的温度范围内,其育性转换过程随光周期的变化而发生,光周期对育性的影响远大于温度的影响。与其他类型雄性不育材料比较,皖901S通过长日条件下自交更易保持,且短日条件下育性表现稳定,雄性败育彻底,并能为大多数普通小麦品种所恢复。皖901S的两系杂种F1代优势明显,它的育成为小麦杂种优势利用开辟了一条新途径。
Anhui 9015 is a new type of light-sensitive male sterile line discovered and bred by Crop Research Institute of Anhui Academy of Agricultural Sciences. The material showed all-sterility under the condition of short day and low temperature in Hefei (N31 ° 51 °), and was normally fertile under long-day warm conditions. In the normal temperature range of wheat development, the process of fertility conversion takes place with the change of photoperiod, and the photoperiod affects the fertility much more than the temperature. Compared with other types of male-sterile materials, Anhui 901S could be more easily maintained by inbreeding under long-day conditions and its fertility was stable under short-day conditions. The male abortion was complete and could be recovered for most common wheat varieties. Anhui 901S two-line hybrid F1 generation obvious advantages, its breeding into wheat heterosis utilization opened up a new way.
