矮败小麦是具有矮秆基因标记的太谷核不育小麦。根据轮回选择的基本原理和方法 ,结合矮败小麦的特点 ,我们逐步建立起一套简单易行的群体改良方法。其主体技术包括组建一个好的基础群体 ,利用控制授粉向群体引进优良基因 ,通过开花前不良可育株的淘汰提高优良基因的频率 ,借助于可育株与不育株的异交使基因重组 ,以及正确地选收矮秆不育株。利用上述方法和技术 ,已经建立了矮败小麦改良群体 Dwarf wheat is Taigu nuclear sterile wheat with dwarfing genetic markers. According to the basic principles and methods of reincarnation, combined with the characteristics of dwarf wheat, we gradually establish a simple and easy method of group improvement. The main techniques include the establishment of a good basic population, the use of controlled pollination to introduce fine genes to the population, and the elimination of poorly fertile plants before flowering to improve the frequency of good genes, by means of male-sterile and male sterile lines that make genetic recombination , And properly selected dwarf sterile line. Using the methods and techniques described above, an improved population of dwarf wheat has been established
