From the view of methodology for genetic improvement of japonica cytoplasmic male sterile (CMS) lines, the breeding of the dwarfabortive type(DA type) japonica CMS line Chunjiang 95A with wide compatibility was described. The biological characteristics of the DA type Chunjiang 95A and its isonuclear alloplasmic CMS line DianI type Chunjiang 95A were investigated. The results showed that the DA type Chunjiang 95A was a japonicalinous CMS line and mainly typical abortive, and had a better fertility stability than stained abortion type japonica CMS lines. The DA type Chunjiang 95A was featured by high stigma exsertion, good flowering habit, high outcrossing rate and wide compatibility. Its recoverability was different from stained abortion type japonica CMS lines. In addition, genetic improvement of the typical abortion type japonica CMS lines and the application prospects of heterosis were discussed.
