Abstract
combinations crossed by 4 male sterile line and 3 restoring line were selected to analysis the combination ability and heritability in major quantitative characters of hybrid rapeseed. The result showed that both general and special combining ability of the major quantitative characters were obvious, in genetic deviation but the general combining ability was more important. For the heritability, the characters of siliques on per plant, seeds in per siliques, 1 000-seeds weight were proved having higher narrow heritability, So additive effect is the main genetic action for quantitative character in hybrid rapeseed. Also, one good combination was selected in this experiment.
