摘要
本文叙述了优质甘蓝型油菜(B.napus)三系杂种优势利用研究的概况。在实现了甘蓝型油菜低芥酸“三系”配套的基础上,又获得了较稳定的“双低”三系材料。现有低芥酸杂交油莱在有效分枝数、单株角果数和每果粒数等因素方面,表现了一定的优势。研究表明,优质甘蓝型油菜“三系”与原有普通甘蓝型油菜“三系”一样,具有保持材料比较广泛,制种技术比较简便等特点。
In the paper the research on utilization of three-line heterosis in good quality Brassica napus is described. Following that the three paren-tal lines with low erucic acid in B.napus were all successfully developed, the stable three line materials with both low erucic acid and low thiogluco-side were obtained.The existing B.napus hybrids with low erucic acid express significant heterosis in yield constituents such as the number of effective branches,pods per plant and seeds per pod. The research work has showed that the three parental lines in good quality B.napus and those in no-good quality B.napus have some common advantage. Such as,the maintainer line materials are abundant, and the technique for seed production is rather simple.
