中文摘要:

为了有效利用引进的燕麦种质资源，促进黑龙江西部农牧交错区燕麦品种的高效利用与新品种选育，比较了66份引进燕麦种质资源的饲草产量、营养指标及其饲喂价值评估指标，以相对牧草质量和粗饲料分级指数3综合评定了饲草营养价值，并利用聚类分析对各品种饲草产量和营养价值进行了综合评价。结果表明，66个燕麦种质资源中，T07和坝莜12号饲草产量最高，为最适宜黑龙江西部地区种植、推广的高产草量燕麦品种；Heacharrelyngby营养价值最高，其次是都3、T19、三分三、74-N-29和白燕2号，为最适宜黑龙江西部地区种植、推广的高品质燕麦品种；通过聚类分析将供试种质分为5类，以种质群Ⅱ饲草产量最高、营养价值最低，种质群Ⅲ饲草产量最低、营养价值最高。

英文摘要:

In order to effectively utilize the introduced oat germplasm resources, to promote the efficient utilization of oat varieties and breeding of new varieties in the ecotone of agriculture and animal husbandry in the western area of Heilongjiang Province, the forage yield, nutritional index and feeding value evaluation index of 66 imported oat germplasm resources were compared, and the nutritional value of forage was synthetically evaluated by RFQ and GI″. The forage yield and nutritional value of each variety was comprehensively evaluated by cluster analysis. The results showed that T07 and Bayou 12 had the highest forage yield and they were the most suitable high-yield oat varieties for planting and popularizing in the western area of Heilongjiang Province; Heacharrelyngby had the highest nutritional value, followed by Du 3, T19, Sanfensan, 74-N-29 and Baiyan 2, which were the most suitable high-quality oat varieties for planting and popularizing in the western area of Heilongjiang Province; the tested oat germplasm was divided into 5 types by cluster analysis, and germplasm group II had the highest forage yield, the lowest nutritional value, and germplasm group III had the lowest forage yield and the highest nutritional value.
