摘　　要：冰草是干旱、半干旱地区生长的一种优良牧草,在生产上具有重要的应用价值。本研究利用灰色关联度分析法对24份冰草种质进行生产性能和营养品质综合评价。结果表明:新疆冰草野生资源在株高、叶部性状及生物产量等生产性能上具有优势,其中,WG3材料的鲜草产量为14346.33 kg/hm^(2),较对照品种诺丹、蒙农分别高31.94%、25.33%;在营养品质方面,部分野生材料在酸性洗涤纤维、粗蛋白含量、粗脂肪含量等指标上更优,其中,WG3材料的粗蛋白含量最高,为11.78%,其次为WG8、WG16含量分别为10.65%、10.18%,均与对照品种蒙农(8.56%)相比差异显著(P<0.05)。通过灰色关联度分析,其中综合评价值最高的新疆冰草材料为:WG3、WG19、WG6。Agropyron cristatum is an excellent forage grass species growing in arid and semi-arid regions with important application value in production.In this study,grey correlation analysis was con⁃ducted for a comprehensive evaluation of the production performance and nutritional quality of 24 acces⁃sions of A.cristatum.The results demonstrated that wild resources of A.cristatum in Xinjiang exhibit advantages in plant height,leaf characteristics,biomass yield,and other production performances.The fresh biomass yield of WG3 was 14346.33 kg/hm^(2),which was 31.94%and 25.33%higher than control cultivars,‘Nuodan’and‘Mengnong’,respectively.For nutritional quality,some wild materials are supe⁃rior in parameters such as acid detergent fiber,crude protein content,and crude fat content.WG3,in par⁃ticular,had the most crude protein content at 11.78%,while crude protein content of WG8 and WG16 were slightly lower at 10.65%and 10.18%,respectively.All three accessions had significantly higher(P<0.05)crude protein content compared to control cultivar‘Mengnong’(8.56%).Grey correlation analysis revealed that WG3,WG19,and WG6 had the highest comprehensive evaluation values in A.cristatum materials from Xinjiang.
