摘　　要：为筛选出适宜青海省东部农业区种植的莜麦优良新品种,2008～2009年选取3个引进莜麦品种(系),以青海省当地品种青莜2号为对照,采用单因素随机区组设计在青海省互助县进行了莜麦品种比较试验。试验结果表明:2008～2009两年间,坝莜6号产量均位居第一,分别比对照增产27%、17.2%;晋九的茎杆粗壮、生物产量高,适宜作为粮饲兼用型品种。In order to screen quality oat varieties that is suitable for the agricultural region in eastern Qinghai Province,three introduced oat varieties（lines） were selected as experimental material,and one Qinghai local cultivars（Qingyou No.2） was taken as control.Then the comparative tests among oat varieties were conducted by single factor randomized blocks design method in Huzhu County of Qinghai Province during 2008～2009.The changes of economic characters,biomass and grain yield of experimental material were integrally contrastively analyzed.The result showed that the grain yield of Bayou No.6 ranked first during 2008～2009,which increased by 27% and 17.2% over control,respectively;Jinjiu can be used as a seed-grass type because of its high biomass and strong stem.
