摘　　要：用细胞遗传学分析方法 ,将龙麦 1 2×龙麦 1 5的杂种核导入不同细胞质中 ,观察不同细胞质对 F1、F2 性状分离的影响 .普通小麦细胞质存在种内变异 ,不同类型的细胞质增加了核质杂种在 F2 代的分离 ,核质互作引起不育中微核数与不育无显著相关 ,杂合核在 F2The hybrid F 1 between Longmai 12×Longmai 15 crossed with different cytoplasmic lines in order to investigate the alloplasmic effect on character segregation in F 1 and F 2 generation. The methods of cytogenetics was used. Different alien cytoplasms appeared different effects on segregation of characters of hybrid F 2. There is variation in the cytoplasm of common wheat. There is not correlation between sterility induced by nucleoplasmic. The variation was induced by nucleoplasmic interaction in generations.
