摘　　要：通过因子分析法,对16个油菜品种(系)的根肿病抗性和主要农艺性状进行了综合性评价。结果表明,1)通过因子分析,共提取2个特征值大于1的公因子,分别是经济指标因子和品质指标因子,二者累计方差贡献率86.637%,可代表原5个评价因子进行综合评价。2)综合得分排名与种植效益趋势较为吻合,表明评价结果可靠有效。油菜品系18ZP05、18苗337、18ZP01和SHR02在该根肿病发病区表现稳定且有较高的种植收益,可考虑在当地根肿病发病区域进行进一步的种植推广。To evaluate the clubroot disease-resistant and agronomic characteristics of 16 rapeseed varieties at Duodao District of Jingmen City, factor analysis was performed in this study. The results showed that two common factors(characteristic root >1), the economic index factor F1 and quality index factor F2, were extracted using factor analysis method. Their cumulative variance contribution rate reached 86.637%, which could fully represent the information of original data. The score trend of rapeseed was basically consistent with planting benefit trend, indicated that evaluatoin results were reliable and valid. Rapeseed varieties 18 ZP05, 18 Miao-337, 18 ZP01 and SHR02 had good performance and higher planting benefit, and could be considered suitable to extend at local area in Jingmen City.
