摘 要 :调查了10种不同山羊草(Aegilops)细胞质的异质小麦品种 Chris 与1B /1R 小黑麦易位系77(2)杂交 F_1及回交后代的育性表现,结果表明:1.在同核背景下,山羊草不同种的细胞质在对77(2)的育性反应上明显不同,依此差异进行特定的质核组配,能得到更宜于培育杂种小麦的新型不育系;2.不同的不育胞质在同核背景下虽都能产生雄性不育,但
Abstract:The fertility of F_1 and backcross progenies from crosses between the alloplasmic wheatvarieties Chris with 10 different Aegilops cytoplasms and 77(2),a 1B/1R wheat-ryetranslocation line,was investigated.The results indicated that:1)under the genetic back-ground of the same nucleus cytoplasms of dif
