摘要:

【目的】比较DTOPSIS法和灰色关联度法在春油菜新品种综合评价中的应用,为春油菜新品种的选育提供参考。【方法】采用熵值赋权的DTOPSIS法和灰色关联度法,对参加2021年陕西省春油菜区域试验的9个品种的11个性状进行综合评价,并比较分析两种方法在评价能力上的优劣。【结果】利用熵值赋权避免了评价结果的主观性;DTOPSIS法和灰色关联度法综合考虑了油菜的多个性状,避免了评价标准的单一性。各性状指标在赋予相同权重的情况下,DTOPSIS法和灰色关联度法的排序结果基本相同,但DTOPSIS法的Ci值最大差异为81.23%,灰色关联度法的Gi值差异仅为41.71%。与仅依据产量高低排名的趋势线相比,灰色关联度法的Gi值排名与DTOPSIS法的Ci值排名趋势线更吻合。相关性分析表明,DTOPSIS法的Ci值排名与灰色关联度法的Gi值排名呈极显著正相关,与仅按产量表现的排名相关性不显著。【结论】DTOPSIS法和灰色关联度法均能全面客观地对春油菜新品种进行评价,但利用DTOPSIS法评价时品种间的差异表现更充分,比灰色关联度法评价效果更好。

Abstract:

【Objective】Compare the application of DTOPSIS method and grey correlation analysis method in comprehensive evaluation of new spring rapeseed varieties,to provide references for the breeding of new spring rapeseed varieties.【Methods】Using the entropy weight DTOPSIS method and grey correlation analysis method,comprehensive evaluation was conducted on 11 traits of 9 varieties in the 2021 Shaanxi Province spring rapeseed regional trial. The advantages and disadvantages of the two methods in evaluation ability were compared and analyzed.【Results】The use of entropy weight avoided the subjectivity of evaluation results. DTOPSIS method and gray correlation analysis method comprehensively evaluated multiple traits of rapeseed,avoided the unicity of evaluation criteria.When each trait index was given the same entropy weight,the sorting results of DTOPSIS method and gray correlation analysis method were basically the same,but the biggest difference of Ci value in DTOPSIS method was 81.23%,and the biggest difference of Gi value in gray correlation analysis method was only 41.71%. Compared with the ranking trend line based on yield only,the trend lines of gray correlation analysis method Gi value ranking and DTOPSIS method Ci value ranking were more consistent. The results of correlation analysis showed that DTOPSIS method Ci value ranking was significantly positively correlated with the gray correlation analysis method Gi value ranking,but not significantly correlated with the ranking based on yield.【Conclusion】Both DTOPSIS method and gray correlation analysis method could comprehensively and objectively evaluate new spring rapeseed varieties. However,using DTOPSIS method to evaluate the differences between varieties was more comprehensive and the evaluation effect was better than the gray correlation analysis method.

Key words: Spring rapeseed, DTOPSIS method, Gray correlation analysis method, Comprehensive evaluation, Entropy weight
