基于熵权法和灰色关联度分析法的油菜品种综合评价
Comprehensive Evaluation of Oilseed Rape Varieties Based on Entropy Weight Method and Grey Correlation Analysis
摘要
Abstract
To screen and evaluate elite oilseed rape varieties(lines)suitable for cultivation in the ecological regions of Xizang,this study conducted adaptability screening and evaluation on 15 rapeseed varieties(lines).Eleven agronomic traits,including growth period,plant height,number of effective branches,main inflorescence length,number of siliques on the main inflorescence,silique density,silique length,number of siliques per plant,seeds per silique,1 000-grain weight,and seed yield,were measured.The entropy weight method and grey correlation analysis were employed for comprehensive evaluation.The results showed that the top five varieties(lines)in terms of yield were'QH281','QH383','50Y9','Zaoza 13',and'Liyouza 5R'.The number of siliques on the main inflorescence had the highest coefficient of variation(25.06%),while the growth period had the lowest(2.64%).The growth period,silique length,and 1 000-grain weight had the highest weights,being the main indicators affecting the comprehensive evaluation results.The grey correlation analysis ranked'QH383','15049',and'50Y9'as the top three varieties based on equal-weight correlation degree and weighted correlation degree.Considering both yield performance and comprehensive evaluation results based on grey correlation analysis,'QH383'and'50Y9'with yields of 4 020.67 and 3 826.54 kg/hm2,respectively,were identified as high-quality varieties suitable for promotion in Xizang.关键词
