Abstract: Hybridization experiment was made in the study using 3 wide compatibility varieties with 24 japonica rice cytoplasmic male sterile (CMS) lines and 9 indica rice CMS Hues, 8 economic characters and their heterpsis were estimated. The results showed that 02428 had no restoring ability to indica rice CMS lines, but did to some of japonica rice CMS lines;Peiai 64 and CPSL 017 were able to restore indica and japonica rice CMS lines.The grain yield competitive heterosis of 5 hyhridization combinations was distinguished, it was mainly manifested in distinct increase of grain number per ear and ear number per plant. The superior hybridization combinations with high spikelet fertility could be selected from the F1 generation combining 3 wide compatibility varieties with indica and japonica CMS lines, Moreover the 3 varieties were characterized by fine economic characters, midle plant height and suitable growth period duration. Therefore, the 3 wide compatibility varieties are able to directly use in Hebei province, among them Peiai 64 is of the most great value in use.

Key words: Wide compatibility varieties, Cytoplasmic male sterile (CMS) line, Hybridization, Fertility restoration
