油菜显性核不育三系法制种，是用纯合两型系（基因型：不育株ＭｓＭｓｒｆｒｆ，可育株ＭｓＭｓＲｆｒｆ）、临保系（基因型ｍｓｍｓｒｆｒｆ）、恢复系（基因型＿＿ＲｆＲｆ）三系配套制种的新技术。其做法是，先用纯合两型系与临保系按核不育油菜二系制种法生产全不育系（基因型Ｍｓｍｓｒｆｒｆ）；再用全不育系与恢复系配制杂交种。纯合两型系育性分离比例稳定在１∶１，繁殖时每公顷产两型系种子５８０．５千克；临保系的保持株率（全不育系）在９９．５％～１００％，全不育系的繁殖每公顷产种４１４～５８５千克；恢复系的恢复株（Ｆ１）率达到９８．０％～１００％，Ｆ１制种每公顷产杂交种子８７６千克。已筛选到一批强优势杂交组合，其中（６ＣＡ×村青）Ｆ１已在生产上试种１万公顷以上，并收到良好效果。
The three lines of dominant genic male-sterile rapeseed (Brassica campestris ssp. Tritici) were identified by homozygous two genotypes (genotype: sterile strain MsMsrfrf, fertile strain MsMsRfrf), genotype (msmsrfrf), restorer line (genotype_RfRf) Department of supporting seed production of new technologies. The method is to firstly use the homozygous two-line type and the semi-sterile line to clone the sterile line (genotype Msmsrfrf) according to the male sterile rape two-line system; The proportion of homozygous two-type fertility segregation was stable at 1: 1, and 580.5 kg of two-type seeding per hectare when propagated. The maintainer rate of all maintainer lines (all-sterile line) ranged from 99.5% to 100% , All-sterile breeding ranged from 414 to 585 kg per hectare; the recovery rate of restorer lines (F1) reached 98.0% -100%, F1 hybrids produced 876 kg of hybrid seeds per hectare. A number of strong hybrid crosses have been screened, among which F1 (6CA × Village Green) F1 has been planted with more than 10,000 hectares in production and received good results.
