小麦复合杂交,稳定时间一般需要年限较长,如何缩短育种时间,加快育种步伐是一个急切需要解决的重要问题,前人已经肯定了单倍体育种和一年多代,对缩短小麦育种年限的价值,但是前者成功率较小,后者又受人力和条件的限制,所以迄今尚存在一些问题.近年我们从太谷不育小麦的杂交实践中,发现用杂合的不育株与稳定的亲本品种进行杂交,F_1 Wheat hybridization, the stabilization time generally takes a long time, how to shorten the breeding time and accelerate the pace of breeding is an urgent need to solve the important issue, the predecessors have affirmed the haploid breeding and more than a year, to shorten the breeding time of wheat Value, but the success rate of the former is small, and the latter is limited by manpower and conditions, so there are still some problems so far.In the past few years, we crossed the Taigu sterile wheat practice and found that heterozygous sterile and stable The parents breed, F_1
