摘要: 为提高油菜中油份和油酸等品质性状的含量,根据油菜遗传规律和育种经验,总结出了油菜品质育种的新方法——优群优选法。该方法的核心是构建目标品质的优类群,低世代(F1~F2)开放选择,中世代(F3~F5)套袋自交和开放单株优选同步进行,待F6~F8代形成稳定的高产高品质株系后,利用多环境种植测定其产量和品质的稳定性,选出目标性状变异幅度小、品质优异、产量高的品系参加各级试验。以该方法选育出浙油50、浙油51、浙油33、浙油21等含油量高于47%的品种,其含油量和产量处于国内领先水平,并育成了我国第1个高油酸品种浙油80。

Abstract: In order to improve the contents of oil and oleic acid in Brassica napus, a new method of rapeseed quality breeding, advanced selection based on superior pool was put forward according to the genetic law of oil content and combined with many years of breeding experience. The core of this method was the construction of superior groups pool quality, superior combinations selection of natural pollination in low generations (F1-F2), individual plant selection of self-pollination and natural pollination in the middle generations (F3-F5). The yield and quality stability of rapeseed were determined by using the multi-environment cultivation after the formation of stable strains of high yield and high quality in F6-F8 generation. Lines with small variation range, excellent quality and high yield were selected to participate in all levels of testing. The oil content of Zheyou 50, Zheyou 51, Zheyou 33 and Zheyou 21 bred by the method were higher than 47%. The oil content and yield were in the domestic leading level. Zheyou 80 was the first variety with high oleic acid in China.
