摘　　要：In order to obtain hazelnut lines with the characteristics of strong cold re- sistance, large fruit and high quality capable of overwintering safely in Yanbian ar- eas, with 173 lines of Corylus heterophylla × C. heterophylla ×C. avellana hazelnut as materials, fruit-related characters were measured and analyzed. Eight excellent individuals were preliminarily selected for further identification of cold resistance and high yield. They selected single plants were 57-1, 57-3 and 55-24 of combination 6- 34-1×S1-5, 56-3, 56-5 and 55-19 of combination 6-34-1×S3-1, 21-12 of combination 6-37-2×S3-1 and 21-12 of combination 6-23-1×S3-1.为了选育抗寒、大果,优质的,能够在延边地区安全越冬的榛子优良株系,该实验以8个组合173株平欧杂交榛子为材料进行了相关果实性状的测定及分析,初步筛选出8株优良单株,作为进一步进行抗寒性及丰产性鉴定的材料。分别为6-34-1×S1-5组合的57-1、57-3、55-24;6-34-1×S3-1组合的56-3、56-5、55-19;6-37-2×S3-1组合的21-12和6-23-1×S3-1组合中的38-24。
