【Abstract】 F 1 fertility of crosses between 368 local varieties collected in Guizhou and CMS (cytoplasm male sterile) lines respectively was tested. The results showed that some of rice germplasm with restoring genes to CMS lines existed in local varieties in Guizhou natural environment, and how to use it to improve the genetic diversity of restorer in hybrid rice breeding was also discussed.更多还原
