摘要
T.spelta1 BS染色体导入 K型小麦不育系 (K3 3 1 4A) ,育成非 1 B/1 R类型 K 型小麦不育系KTSP3 3 1 4A,研究其遗传效应。结果表明 ,T.spelta1 BS染色体导入使非 1 B/1 R类型 K型小麦不育系更易恢复 ;不育系本身不产生单倍体 ,其杂交种 F1 产生极少或不产生单倍体 ;农艺性状除了株高具有明显的优势外 。
The effect were studied on breeding Non 1B/1R K type male sterile wheat line by means of chromosome transfer. The result indicated that T. spelta 1BS chromosome make Non 1B/1R K type male sterile wheat line have better fertility restoring feature and less haploid. There were better genetic effects on almost all agronomic characters except for the plant height.
