| Abstract: | Rice restorer line R894 was developed from the cross of Shuhui527 and Minghui86,which is a newly developed heavy-panicle restorer line with high cold tolerance,heavy pollen load,strong restoring force and good combining ability after selecting in other places for many years and stepwise polymerizing parents' protogene.By crossing it with sterile line G98A,the combination of Qinyou894 passed examination and approval to extension by Guizhou Agricultural Variety Approval Commission in June,2008. |
