| Abstract: | Typical CMS and inbreed lines were investigated by genetic and molecular methods. 21CMS lines were analyzed and classified into 5 types according to their cytoplasmic genes. After Southern analysis 4 kinds of patterns were discovered at atpA locus. Based on their CMS types, the relationship between restoration and maintenance in 20 inbreed lines were analyzed. Furthermore, the types of restoration genes in 11 inbreed lines were also determined. The results indicated that 6 lines contain Rf1 gene, and other 5 lines do not contain. |
