K型小麦1B/1R 易位雄性不育系细胞质效应,从生长势等10个性状看,有好有坏,但苗期生长普遍较弱;产生单倍体频率平均6.7%,但不育系 K—6901A 和 K—E5—1A 未发现单倍体,说明从现有品种中可以筛选出不产生单倍体的保持系。
The cytoplasmic effects of the 1B / 1R translocation male-sterile lines in K-type wheat were good or bad from the ten traits of growth vigor, but the growth was generally weak at the seedling stage. The frequency of haploid generation was 6.7% No haploid was found in K-6901A and K-E5-1A, indicating that haploid-free maintainer lines can be selected from the existing varieties.
