摘要
为提高矮败小麦在小麦育种中利用价值,选用9个矮败小麦杂交组合,结合小麦×玉米诱导单倍体技术,每个组合处理4个可育株,每株处理1穗,共80朵小花。各组合平均得胚率为12.4%,加倍率达到50.8%,并获得32个双单倍体小麦单株。
In order to raise the application value of dwarfing-sterile wheat in breeding,9 hybrid combinations of dwarfing-sterile wheat were selected,incorporating the technique of induction haploid by wheat×maize hybridization.1 fertile plants and 80 flowers were treated in each combination.The result showed that the average frequency of embryo formation was 12.4%,frequency of doubling was 50.8%.32 double-haploid wheat plants were obtained.
