摘　　要：为了筛选出适宜新疆喀什地区复播种植的谷子新品种,同时为谷子品种筛选提供一种新的综合评价方法。本研究以‘冀杂金苗’、‘豫谷18’、‘陇谷32’、‘陇谷29’、‘陇谷23’共5个谷子品种为试材,选择11个评价指标(产量、生育期、株高、穗长、单株草重、单穗重、穗粒重、千粒重、出米率、抗倒伏、谷瘟病),利用熵权法对各评价指标赋权,采用DTOPSIS法对其进行综合评价。结果表明谷子品种的抗倒伏性、谷瘟病对谷子品种的综合评价影响较大,权重分别为0.6191和0.2327,‘豫谷18’和‘冀杂金苗’排在第一位和第二位,但‘豫谷18’的产量明显低于其他品种,排在最后一位,‘冀杂金苗’产量排在第三位。‘冀杂金苗’(0.7468)综合性状稳定,产量中上,为3906.75 kg/hm^(2),适宜在喀什地区复播种植推广,替代‘豫谷18’。This study aimed to select summer millet varieties suitable for planting in Kashgar of Xinjiang and provide a new comprehensive evaluation method for millet varieties screening.The DTOPSIS method based on entropy weight was applied to comprehensively evaluate 5 millet varieties planted in Kashgar,Xinjiang.11 characters including yield,growth period,plant height,spike length,grass weight per plant,single spike weight,grain weight per spike,1000-grain weight,milling ratio,lodging-resistance,Pyricularia setariae were selected for the evaluation.The results showed that the lodging resistance and Pyricularia setariae of millet varieties had great influence on the comprehensive evaluation of millet varieties,and the weights were 0.6191 and 0.2327,respectively.‘Yugu18’and‘Jizajinmiao’ranked first and second,but the yield of‘Yugu 18’was significantly lower than other varieties,ranking last,and‘Jizajinmiao’ranked third.‘Jizajinmiao’(0.7468)has stable comprehensive traits and good yield of 3906.75 kg/hm^(2),which is suitable for multiple cropping in Kashgar,Xinjiang,replacing‘Yugu18’.
