Abstract: Twenty-four combinations were made with eight new breeding restorers and three CMS lines including Chuangxiang 29A(A1)、Zhenshan 97A(A2) and Ⅱ-32A(A3) by incomplete dialled crosses. Forecasted application of eight restorers and estimate ascendancy of the combinations and parents throught analyzing the combining ability and heritability of 12 main agronomic characters. The results showed: in eight restorers, R9 were the most ideality, R8 and R7 were the less. At the effects of SCA, three combinations, A2R2、A1R5、A3R9 were superior. At the aspect of 12 main agronomic characters, the dominance of 5 combinations, A2R9, A3R9, A1R3, A1R9, A1R8, was higher.
