Research on Comprehensive Evaluation of Xinjiang Cotton Early and Middle Maturity Regional Trial Varieties Based on DTOPSIS Method
Using DTOPSIS method to make more reasonable analysis and evaluation of early and medium maturing cotton varieties in Xinjiang regional trials.Based on the survey data of 40 participating varieties in the 2020 Xinjiang Autonomous Region cotton early and medium maturing regional trial,the DTOPSIS method was used for comprehensive analysis and evaluation.The preliminary study investigated the application of this method in the evaluation of early and medium maturing cotton regional trial varieties in Xinjiang.The results showed that the DTOPSIS method was more reasonable than analyzing only production volume,summarize the trait indica-tors of each variety into unified quantitative comprehensive indicators,and it could reflect the stability of various varieties.Among the 40 tested varieties,Tahe 7,Xin 827,and Hemian AW5 had relatively high Ci values and good overall traits,consistent with actual per-formance.In conclusion,using DTOPSIS method to evaluate cotton early and middle maturing regional trial varieties could comprehen-sively analyze the adaptability of cotton varieties and effectively improve the success rate of new variety promotion.
