摘　　要：以种子含油量达到50%为主攻目标,自1998年以来采用品种间杂交和系统育种相结合的方法,以含油量起点较高的群体为选择对象,运用种子含油量的正向选择与种皮色泽负向选择相结合的筛选技术,育成了HOC1、HOC2和HOC3等3个种子含油量达到50%的甘蓝型油菜新种质。其年度间含油量性状较为稳定,综合性状良好。同时还比较了同一遗传背景下高、低油分品系角果皮与种子油分积累的差异,高含油量品系角果皮具有较强的油份积累与转移效率。Having target at 50% oil content in rapeseed, the high oil content lines HOC1, HOC2 and HOC3 were crossed among varieties and succession oil content selection in its offspring. The oil content in these lines, which had superior agronomy and quality traits were stable among different years. The difference of oil content accumulation in silique- coat and seed between high and low oil content near - isogenic lines was compared, the silique - coat of high oil content lines could accumulate and transfer oil more efficiently.
