摘　　要：运用DTOPSIS法对参加2021年河南省谷子区试的18个谷子品种(系)进行了综合评价,为区试试验鉴定和谷子品种(系)区试评价提供新的方法。结果表明,谷子的生育期、株高、穗长、穗粗、单穗重、穗粒重、出谷率、千粒重和产量分别赋予0.0500、0.0500、0.0500、0.0500、0.1000、0.0500、0.0500、0.1000、0.5000的权重值。DTOPSIS法计算出的结果排名与产量排名有所差异,DTOPSIS排名和产量排名在前4位的谷子品种相同,但位次有所变化;其中3个谷子品种在DTOPSIS排名和产量排名中结果一致,其他谷子品种有所变化。DTOPSIS评价方法可以作为谷子新品种区试评价的一种方法。The DTOPSIS method was used to comprehensively evaluate millet regional trials for 18 millet varieties(lines)in Henan Province in 2021,which provided a new approach for identifying and evaluating millet varieties(lines)in the regional trial.The results showed that the growth period,plant height,ear length,ear diameter,single ear weight,ear grain weight,grain yield,thousand-grain weight,and yield of millet were assigned weight values of 0.0500,0.0500,0.0500,0.0500,0.1000,0.0500,0.0500,0.1000,and 0.5000,respectively.The ranking calculated by the DTOPSIS method was different from the yield ranking.The top four millet varieties had no difference in the DTOPSIS ranking and yield ranking,though their specific order changed.Three millet varieties had consistent rankings in both DTOPSIS and yield evaluations,while other varieties showed differences.The DTOPSIS evaluation method can be effectively used for evaluating new millet varieties in regional trials.
