【摘要】 中国的油菜育种研究技术从常规育种发展到生物技术和杂交育种相结合,杂种优势利用从最初的三系法正在逐渐向两系法过渡,最终将实现一系法杂种优势利用。育种目标也从最初的产量育种到双低育种,再到今天的"高效型优质油菜"育种,包括在双低基础上,进一步改良油菜籽的品质,提高单位面积产油量,实现油菜生产的全程机械化操作等,说明我国油菜育种研究已经发生了质的飞跃。更多还原

【Abstract】 The research techniques of rapeseed breeding from conventional breeding to biotechnology development combine breeding and cross breeding,heterosis developes from the original three-line to the two-line method and from traditional breeding to biotechnology breeding.The breeding goals also develope from the initial output breeding to the breeding pairs of low-and then to "high-quality type rape "breeding,including in the basis of double-low,further improving the quality of rapeseed,substantial increasing in oil production per unit area and achieving full mechanization of production operations rape.The qualitative leap of rapeseed breeding has taken place.更多还原
