我国油菜面积占全国油料作物总面积的40%以上,产量占30%以上,近年来又有新的发展。但现有生产的品种,含油量偏低,芥酸偏高,还含有有害物质硫葡萄糖甙,急待研究改良。本专题的研究内容及预期目的是:(一)研究高油份与低油份、高芥酸与低芥酸油菜品种间脂肪及脂肪酸组成的积累变化差异,为品质育种的亲本选配提供依据:(二)观察油菜发育胚中脂肪形成规律及脂肪酸组成中油酸与芥酸、花生烯酸积累的相互关系。 China’s rapeseed area accounts for more than 40% of the total area of ​​oilseed crops in the country, accounting for more than 30% of the total output. In recent years, there have been new developments. However, the current production of varieties, low oil content, high erucic acid, but also contains harmful substances thioglucoside, urgent research and improvement. The research contents and expected objectives of this topic are: (1) to study the differences in the accumulation and accumulation of fat and fatty acid composition between high-oil and low-oil, high-erucic acid and low-erucic acid rapeseed varieties and provide evidence for the selection of parents for quality breeding (2) Observe the rules of fat formation in rape embryos and the relationship between oleic acid and erucic acid and arachidonic acid accumulation in fatty acid composition.
