摘　　要：对5份新疆野生偃麦草(Er04、Er06、Er07、Er09、Er10)和5份引进的偃麦草(Er01、Er02、Er03、Er05、Er08)从生物学特性(生育期、形态特征)、坪用性(质地、盖度、颜色、均一性、绿色期等)及牧用性方面进行了研究。结果表明:供试材料在种内差异较大;Er04、Er07植株低矮、叶片较纤细柔软,坪用性好;Er05、Er10植株高大、叶片宽、叶量多、产草量高,牧用性好。通过聚类分析,初步将10份偃麦草分为3大类群,即草坪型(Er04、Er07)、草坪草牧草兼用型(Er01、Er02、Er03、Er06、Er08、Er09)和牧草型(Er05、Er10)。Ten Elytrigia repens （Five Xinjiang natural materials were Er04,Er06,Er07,Er09 and Erl0. Five introduced materials were Er01 ,Er02,Er03,Er05 and Er08） were primarily studied on their morpho-logical characters,growth stages and lawn estimation etc. The results indicated that the variance of Elytrigia repens was great. Among them,Er04 and Er07 had small-individual,fine-stalk,slim-leaves;Er05 and Er10 had high-individual, strong-stalk, big-leaves, high-yield; others were in the middle. By the clustering analysis, the materials were divided into three different types. There were lawngrass and meadowgrass dual-purpose type including Er01, Er02, Er03, Er06, Er08 and Er09 ; lawn type including Er04 and Er07;forage type including Er05,Erl0.
