发展双低优质油菜是当今世界各国油菜生产发展的趋势和科研的主攻方向。但优质与高产在育种上的负相关效应,使其优质与高产难以统一,使油菜的发展和普及受到了限制。为了攻克这一难题,育种者对利用油菜杂种优势给以普遍的重视,以期通过杂交种在产量、生长和抗性上的显著优势来实现高产与优质的结合和统一。河南省农科院为此
The development of double low-quality rapeseed is the trend of rapeseed production in all countries and the main direction of scientific research. However, the negative correlation effect between high quality and high yield on breeding makes it hard to unify the high quality and high yield, which limits the development and popularization of rape. To overcome this dilemma, breeders have placed a general emphasis on the utilization of rape heterosis, with a view to achieving high yields and quality combinations and unification through the distinct advantages of hybrids in terms of yield, growth and resistance.
