我省引进奥罗油菜成功及大面积推广,对提高油菜产量和改进油品质量起了重要作用。因利用多年,加之良种繁育体系不健全,使奥罗品种已混杂退化,抗病性减弱,产量下降,芥酸回升到10％以上,已失去作为低芥酸油菜品种的利用价值。为此,从1979年以来,我省又引进一批单、双低油菜品种,以丰产、稳产性为重点进行适应性研究,为大面积推广利用提供依据。一、内容和方法 (一)、丰产性鉴定 The introduction of Oleo Rape in our province successfully and large-scale promotion has played an important role in improving rapeseed production and improving oil quality. Due to the use for many years, combined with the imperfect breeding system, the variety of Aurora has been mixedly degenerated, the disease resistance is weakened, the yield is reduced, and the erucic acid is recovered to more than 10%, which has lost its value as a low-erucic rapeseed. To this end, since 1979, our province has introduced a number of single and double low rapeseed varieties, with high yield, stable yield as the focus of adaptability research, to provide a basis for the promotion of large-scale use. First, the content and methods (a), high yield identification
