通过对５８ 份试材的研究，并参考Ｔｈｏｍｐｓｏｎ 等人的欧榛评价系统，初步建立了适合中国东北地区特点的榛属种质资源性状描述与评价系统。同时，研究确定了标准叶片取样部位、数值性状理论样本容量和分级标准。为今后系统研究榛属种质资源提供了依据
Based on the research of 58 samples and referring to the European hazel evaluation system by Thompson et al., The characterization and evaluation system of hazelnut germplasm resources suitable for the characteristics of northeast China was preliminarily established. At the same time, the study determined the standard blade sampling site, numerical traits theoretical sample size and grading standards. It provides the basis for systematically studying hazelnut germplasm resources in the future
