重庆温光型核不育小麦(C49S)的育性表达主要受温度控制,光照长短也起一定作用,在低温短日照条件下不育,温暖长日照条件下可育,它的制种、繁殖技术与三系杂交小麦差异甚大,必须在适合它的温光条件下才能达到制种和繁殖的目的。近几年
The fertility expression of Chongqing cultivars (C49S) was mainly controlled by temperature and the light length also played a certain role. It was sterile under short-day and short-day conditions and fertile in warm long-day condition. Its breeding and breeding Technology and three-line hybrid wheat is very different, must be suitable for its temperature and light conditions in order to achieve the purpose of breeding and breeding. recent years
