为探索甘蓝型油菜突变自交系高油酸性状的遗传模式,以应用于油菜高油酸育种工作。本研究以低油酸亲本‘扬6026’(P1)和甘蓝型油菜高油酸突变自交系‘HO05’(P2)为材料,通过气相色谱单粒法分析对该组合的杂交后代F1、RF1、B1、RB1、B2、RB2、F2和RF2的高油酸性状的进行数量性状遗传分析。试验分析结果表明:亲本的油酸含量比较稳定,为加性-显性遗传模式,并且加性主效基因作用明显,是由于基因遗传差异作用的,高油酸性状由2对主效基因控制高油酸性状,狭义遗传力hN2为63.16%,另外的36.84%是由环境的变化引起的;低油酸亲本(P1)和高油酸亲本(P2)正反交试验表明,高油酸的遗传没有细胞质遗传效应。
In order to explore the genetic model of high oleic traits in inbred lines of inbred lines of Brassica napus, In this study, the low-oleic parent ’Yang 6026’ (P1) and the inbred line ’HO05’ (P2) with high oleic acid inbred rapeseed (Brassica napus L.) were used as materials to analyze F1, RF1 , B1, RB1, B2, RB2, F2 and RF2 of the high oleic trait quantitative genetic analysis. The results of experimental analysis showed that the oleic acid content of the parents was stable and additive-dominance genetic model, and the major gene of additive effect was obviously due to genetic differences. The high oleic acid content was controlled by two major genes High oleic acid trait, hN2 in narrow heritability was 63.16%, and the other 36.84% was caused by environmental changes. The reciprocal crosses between low oleic parent (P1) and high oleic parent (P2) Genetic No cytoplasmic genetic effect.
