基于熵权的DTOPSIS法综合评价赤峰市糜子区域试验品种OA

In this study,13 varieties from the 15th National Regional Trial of Broomcorn Millet(Glutinous)Varieties in 2024 were used as experimental materials.An evaluation system was constructed using 8 representative agronomic and yield-related indicators:growth period,plant height,number of main stem nodes,effective tiller number,main panicle length,grain weight per panicle,1 000-grain weight and grain yield.The DTOPSIS method integrated with entropy weight assignment was then employed to conduct a comprehensive evaluation of the tested varieties in Chifeng City,aiming to provide a scientific basis for elite variety selection.Weight calculation results revealed that effective tiller number(weight coefficient=0.508 37)was the key determinant of broomcorn millet yield.In contrast,growth period(0.000 77)and number of main stem nodes(0.000 90)had relatively minor effects on yield.The comprehensive evaluation rankings of the varieties by the DTOPSIS method from highest to lowest were as follows:Yishu No.13,Jishu No.4,Chishu No.10,Jinshu No.15,4652(2-30),NM18-03,1651(5-33),Yishu No.10,2013FMZ3-1-3,19-174,Chishu No.11,Baimi No.1,and 2023-Y-1.The top-performing variety,Yishu No.13,achieved a Ci value of 0.883 38,while the poorest-performing variety,2023-Y-1,had a Ci value of 0.076 34,indicating a substantial difference between the two.This comprehensive evaluation method balances yield potential and agronomic trait coordination in broomcorn millet varieties,overcoming the one-sidedness of single-indicator evaluation and enabling a systematic assessment of the tested varieties.
