[Objective] To provide scientific evidence for introduction and extending grain and forage millet production in Chifeng City and the crossing zone of agriculture-animal husbandry of Inner Mongolia. [Method] The grey correlative degree analysis was applied to comprehensively evaluate production performance of nine genotypes millet varieties. [Result] The order of comprehensive evaluation was: Chigu4 > Chigu10 > Chigu7 > Fenggu12 > Chigu6 > Chigu9 > Fenggu+1> Chigu5 > Chigu8. The order of weight index in the grey correlation analysis was: dry matter > 1000-grain weight > ear diameter > crude fiber > ear length > crude ash > height length > digestibility > crude protein > seed yield > millet straw yield > ear weight > grain weight per spike. [Conclusion] The results of comprehensive evaluation showed that the better grain and forage millet was Chigu4, ChigulO and Chigu7, the three millet varieties could be planted in Chifeng City and the crossing zone of agriculture-animal husbandry of Inner Mongolia.%[目的]为赤峰地区乃至内蒙古农牧交错带粮饲兼用谷子品种引种及推广提供科学依据.[方法]应用灰色关联度理论,对9个谷子的生产性能进行综合评价.[结果]9个谷子品种生产性能综合评价排序为:赤谷4号＞赤谷10号＞赤谷7号＞峰谷12号＞赤谷6号＞赤谷9号＞峰谷11号＞赤谷5号＞赤谷8号.各项指标的权重大小顺序为:干物质＞千粒重＞穗粗＞粗纤维＞穗长＞粗灰分＞株高＞消化率＞粗蛋白＞种子产量＞谷草干草产量＞穗重＞穗粒重.[结论]经综合评价表现较好的粮饲兼用谷子品种是赤谷4号、赤谷10号、赤谷7号,可在赤峰地区乃至内蒙古农牧交错带推广种植.
