| Abstract: | 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. |
