Abstract: In order to reveal the production potential of different Forage millet(Setaria italica)in saline-alkali dryland around Bohai Sea,a 2 years cultivation experiment was conducted to compare yield traits,agronomic traits,and nutritional components of 23 forage millet. The standard deviation coefficient allocation weight method and the forage roughage Grading index (GI) were used to comprehensive evaluate and analyze different Forage millet. The results showed that there were significant differences in each character index among different Forage millet varieties,the dry grass yield of ‘Wuanyougu Hybrid-1-1’,‘HG001’,‘Yin 90-39’,‘Guchuansu’,‘Handanyougu-11’ and ‘India 0907’ reached 11 000 kg·hm^-2 or higher,forage roughage grading indexes (GI) of ‘cheng 03-992’,‘sicao 4-4’,‘Henggu 15’,‘Yugu 18’,‘Datong 37’,‘Handan Yougu-11’,‘K3201’ were higher than 12.45,the forage quality was relatively good,combined with the comprehensive evaluation of lodging resistance,it is better to use ‘Handan Yougu-11’,‘Henggu 15’,‘India 0906’ and ‘Taixuan 2’. Therefore,it is feasible to plant Forage millet in saline-alkali dry land around the Bohai Sea,and the varieties such as ‘HandanYougu-11’,‘Henggu 15’,‘India 0906’ and ‘Taixuan 2’ should be promoted first.

摘要： 为揭示环渤海盐碱旱地不同饲用谷子（Setaria italica）的生产潜力，本研究通过2年的栽培试验，比较了23个饲用谷子的产量性状、农艺性状、营养成分指标，并采用标准差系数赋予权重法及粗饲料分级指数（Grading index，GI）对不同饲用谷子进行了综合评价分析。结果表明，不同饲用谷子品种间的各性状指标均存在显著差异。‘武安莠谷杂交-1-1’、‘HG001’、‘印90-39’、‘古川粟’、‘邯郸莠谷-11’、‘印度0907’干草产量能达到11 000 kg·hm^-2及以上；‘承03-992’、‘饲草4号-4’、‘衡谷15号’、‘豫谷18号’、‘大同37号’、‘邯郸莠谷-11’、‘K3201’粗饲料分级指数在12.45以上，饲用品质优良；结合抗倒性综合评价，以‘邯郸莠谷-11’、‘衡谷15号’、‘印度0906’、‘太选2号’较好。因此，在环渤海盐碱旱地种植饲用谷子具有可行性，可优先推广‘邯郸莠谷-11’、‘衡谷15号’、‘印度0906’和‘太选2号’。
