摘　　要：以2~6年生的95个系号平榛为材料,通过对其各项经济指标分别赋分并计算综合指标的方法进行评价,以期筛选出综合表现优良的单株,各项经济指标包括单果质量、果径、果形指数、单仁质量、果壳厚度、出仁率、单位面积产量等。通过该方法对95个系号平榛进行比较,并结合生产需要和市场需求等方面的因素,初步确定系号KY-28、TL-26、CT-1、XF-3、TL-9、TL-3等6个系号作为平榛首批优良品系的选育对象,进行扩繁,开展相应的生产性试验。The research was conducted on 95 hazelnut trees at the age of 2 to 6. Scores were assigned to each eco- nomic indicator, and the indicators include nutweight, kernel rate, shape index, shell thickness and yield. The scores were used to calculate the comprehensive indicator aiming at selecting excellent single plant. Based on the resuits of this research and other factors, such as the needs of production and market, six cultivars were selected as the first bunch of breeding subjects： KY-2, TL-26, CT-1 , XF-3, TL-9 and TL-3. And further reproduction and production tests will be performed.
