Abstract:

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.

Key words: wheat, F type male sterile line, chloroplast, mitochondria, SSR
