随着油菜生产的发展,油菜品质已越来越被重视。选育高产、优质(低芥酸、低硫苷)、抗病、综合性状优良的油菜新品种是当前育种工作的方向。在处理试验数据时,由于方差分析和多重比较等方法,容易丢失与产量性状相关的其他性状的信息,造成对品种评价的片面性。模糊权重综合评判法弥补了方差分析的不足,它能对品种(系)的多项因素进行综 With the development of rapeseed production, rapeseed quality has been paid more and more attention. Breeding high yield, high quality (low erucic acid, low glucosinolate), disease resistance, good comprehensive new rapeseed varieties is the direction of the current breeding work. When dealing with the experimental data, due to the analysis of variance and multiple comparison methods, it is easy to lose the information of other traits related to the yield traits, resulting in one-sided evaluation of the varieties. Fuzzy weight comprehensive evaluation method to make up for the lack of analysis of variance, it can variety (Department) a number of factors for comprehensive
