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 F2 代引起的变化较大
Cytoplasmic analysis was used to introduce different kernels of Longmai 1 2 × Longmai 15 into different cytoplasms, and the effects of different cytoplasm on the separation of F1 and F2 traits were observed. There was intraspecific variation in the cytoplasm of common wheat and the increase of different types of cytoplasm The segregation of nuclear hybrids in F2 generation, the correlation between nuclear and cytoplasmic male sterile nuclei and infertility were not significantly correlated, heterozygous nuclei in F2 generation caused greater changes
