摘　　要：科学分析和评价谷子农艺性状、经济性状可为新品种选育提供更多参考。对23份谷子品种性状进行测定,并运用灰色关联度进行综合评价。结果表明,穗粒重的变异系数最高,为29.9%,株高的变异系数相对较低,为12.3%;籽粒产量与穗码密度、穗粒重和株高关联度较高。灰色关联分析表明,23份谷子适宜机收性状综合评价较高的5个品种分别为赤谷K6(0.774)、晋汾121(0.749)、赤谷K4(0.729)、太选谷28(0.721)和陇谷23号(0.692)。上述综合评价较高的材料可作为筛选和培育适宜西北生态区种植的谷子新品种。Scientific analysis and evaluation of agronomic and economic characteristics related to the suitability of foxtail millet can provide more reference for the selection and breeding of new varieties.The characteristics of 23 foxtail millet varieties were determined and a comprehensive evaluation carried out by using the gray correlation degree.The results showed that the coefficient of variation of panicle weight was the highest at 29.9%,and the variation coefficient of plant height was relatively lower at 12.3%;the correlation between grain yield and panicle density,panicle weight and plant height were high.The gray correlation analysis showed that the five varieties with higher comprehensive evaluation of the 23 varieties suitable for mechanized harvesting were Chigu K6(0.774),Jinfen 121(0.749),Chigu K4(0.729),Taixuangu 28(0.721)and Longgu 23(0.692).The above five materials with high comprehensive evaluation can be used to screen and cultivate new foxtail millet varieties suitable for planting in northwest ecological region.
