摘　　要：油研1220是以黄籽双低隐性核不育系8078A与双低恢复系0202R配制成功的黄籽双低杂交油菜新组合。在贵州省2004-2006两年15点次试验中，增产点和增产8％以上的点分别为11个和8个，分别占总点数的73．3％和53．3％，两年平均产量达167．88kg／667m^2，比CK增产7．0％；产油量迭70．72kg／667m^2，比CK增产13．87％。芥酸含量0．6％，硫甙含量28．28μmol／g·饼，含油量达44．03％，种子蛋白质含量达26．85％。选择含油率和蛋白质含量高的转育亲本，在后代分离世代中加强亲本含油率和蛋白质含量的定向选择是提高品种含油率和蛋白质含量的重要选育技术。Youyan 1220 with high yield, oil and protein content, low erucic acid and glucosinolate content was bred from 8078A×0202R. The average yield and producing oil amount was 167.88 kg/667m^2 and 70.72 kg/667m^2 , 7.0% and 13.87% higher than CK respectively during 2004-2006 . The erucic acid, glucosinolate, oil and protein content are 0. 6%, 28. 28 μmol/g, 44.030% and 26.85 % separately. The key breeding technique for selecting varieties with higher rate of oil content and higher protein content includes selecting the trans-parents with higher rate of oil content and higher protein content and strengthening the directive selection of parents in rate of oil content and protein content in the segregation generations.
