摘　　要：为了鉴定F型与其他小麦雄性不育系细胞质类型之间差异。以F型不育系(FA1-1,FA1-2,FA2-1)、F型保持系、T、K、V型同核异质不育系(A)及其保持系(B)‘冀5418’等为试验材料,用23对叶绿体和21对线粒体SSR分子标记进行聚类分析。结果表明:FA与T、K、V、B型不育系的细胞质分属不同类别。FA与中国春(CS)的细胞质遗传相似系数为1.00,FA与FB细胞质遗传相似系数为1.00,表明其可能为普通小麦细胞质雄性不育系。与经典质核互作雄性不育原理有差异,F型雄性不育系的育性可能由核基因控制。In order to identify the difference of cytoplasmic types between F type and other male sterile lines of wheat,the experiment was conducted with F type sterile line(FA1-1,FA1-2,FA2-1),F type maintainer line,the T,K and V type CMS lines(A)and the common maintainer line(B)‘Ji5418’as the materials,and 23 pairs of chloroplasts and 21 pairs of mitochondrial SSR markers were used for cluster analysis.The results showed that the cytoplasm of FA and T,K,V and B male sterile lines belonged to different categories.The cytoplasmic genetic similarity coefficient between FA and Chinese Spring(CS)was 1.00,and the cytoplasmic genetic similarity coefficient between FA and FB was also 1.00,indicating that FA might be a cytoplasmic male sterile line of common wheat.The fertility of F type male sterile line might be controlled by nuclear genes,which is different from the classical cytoplasmic-nuclear interaction male sterile principle.
