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/hm2,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/hm2,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.
