基于熵权法和灰色关联度分析法综合评价谷子品种的农艺性状及产量与品质
Comprehensive evaluation of foxtail millet varieties based on entropy weight method and grey relational analysis
摘要
Abstract
[Objective]It is necessary to determine the most suitable variety under different selection goals and the best comprehensive evaluation method for different selection goals of millet varieties.[Methods]In this study from 2021 to 2022,25 agronomic traits,yield,and quality indicators of 20 new millet varieties were analyzed and compared.Meanwhile,the entropy weight method was used to assign weights to each indica-tor,and DTOPSIS method and grey relational degree analysis method were used to evaluate different varieties.[Results]Except for thousand-grain weight,the differences between varieties in the other 24 indicators reached a highly significant level.The ranking results of the two analytical methods,DTOPSIS and grey rela-tional analysis,showed a higher degree of agreement with the yield ranking results.This indicated that grey re-lational analysis payed more attention to the evaluation of yield than the DTOPSIS method.The maximum differ-ence value of Ci was 30.01％,the maximum difference value of ri was 7.71％,and the maximum difference value of γ was 11.85％,indicating that the DTOPSIS method could better demonstrate the differences between varieties.[Conclusion]The DTOPSIS method and the weighted grey relational analysis method based on en-tropy weight are suitable for the comprehensive evaluation of millet varieties.In semi-arid production areas,if higher yield varieties are needed,Zhangzagu 16 should be selected;if varieties with more balanced traits are needed,Jinmiao K2 should be chosen;if varieties with a balance between yield and various traits are needed,Jigu 22 should be selected.关键词
