| 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 different species of Aegilops showed significantdifference in fertility reaction to 77(2).Using the cytoplasmic variability specificnucleo-cytoplasm combination may be identified and more suitable new male-sterile typefor hybrid wheat can be obtained.2)Although the three different sterile cytoplasms all re-sulted in male sterility under the genetic background of the same nucleus,the ability of fer-tility restoration was different.3)Among the three male-sterile types with Ae.ventricosa,Ae.kotschyi and Ae.variabilis cytoplasm developed in this study,the one with Ae.ventricoisa cytoplasm not only owned more maintainers but also was much more easilycompletely restored.Even more important is that the male-sterile type with Ae.ventricosacytoplasm was stable in sterility,and the seed plumpness of male-steriles F_1 and F_2 werenormal and there was no harmful maternal effect.It opens a new possibility for breedinghybrid wheat. |
