以普通小麦显性核不育材料(Tal 小麦)和 Tal.Kr.phlb 综合体为基础材料,用天蓝偃麦草、八倍体小偃麦和八倍体小黑麦为异种属优良基因的供体进行研究,结果表明,Tal 小麦和 Tal.Kr.Phlb 综合体与天蓝偃麦草杂交,当代结实率分别可达26.4%和31.7%。八倍体小偃麦是普通小麦与天蓝偃麦草杂交良好的桥梁材料。Tal 小麦和 Tal.kr.phlb 综合体与八倍体小黑麦杂交,当代结实率分别可达36.95%和41.76%。显性核不育基因在以上杂交组合的 F_1中可以正常表达。
The common wheat dominant-negative material (Tal wheat) and Tal.Kr.phlb complex as the base material, the use of Thinopyrum intermedium, octoploid triticale and octapeptide as heterologous genus The results showed that the crosses between Tal and Tal.Kr.Phlb complex and Thinopyrum intermedium could reach 26.4% and 31.7% respectively. Octoploid Triticeae is a good bridge material for crossing common wheat and Thinopyrum intermedium. The crosses between Tal and Tal.kr.phlb complexes and octoploid triticale resulted in 36.95% and 41.76% seed set respectively. The dominant male sterility gene can be normally expressed in F_1 of the above hybrid combination.
