| 摘 要： | 以长穗偃麦草(Elytrigia elongata=Agropyron elongatum,2n=70)为母本,普通小麦为父本,进行核置换回交,现已获得第14次回交的核质杂种材料。根据育性和生活力的表现以及细胞遗传学分析,长穗偃麦草-普通小麦核质杂种可分为以下类型:(1)生长正常,育性较好,染色体构型为21″W+1′Eev;(2)生长正常,完全不育或育性很低,染色体构型

| Abstract: | The fourteenth backcrossed NC hybrid plants were obtained from Elytrigia elongata(Agropyron elongatum 2n=70)×T.aestivum(2n=42),with common wheat as the recur-rent parent.According to their fertility,vigour and cytogenetic analysis,the NC hybridplants could be classified into three types:1)Type one |
