Chemical hybridization agents(CHA)for rapeseed at home and abroad and their applied research were summarized in this paper,and the author focused on CHAs of China.According to the applied effect of all CHAs,CHA No.1 and SX-1 and Huashaling in them are better.Male sterility of hundreds of varieties in Brassica napus.L and Brassica campestris and Brasscia juncea was induced by SX-1 CHA respectively,which the authors screened and developed,most of varieties showed good induced effect.The suitable induced time is single nucleus stage that pollen mother cells are developing,and there are about 8 to 12 days from spraying SX-1 CHA to appearing sterility,and sterility may keep 17 to 21 days.Rapeseed flowering stage is generally 25 to 35 days,so to spray SX-1 for breeding hybrids need two times,the second time is the 12th day to the 14th day after the first spraying.
