| 摘要：为综合评判靖州引种的美国山核桃坚果品质的优劣，为美国山核桃育种筛选打下基础。以16个美国山核桃品种和1个湖南山核桃品种为试材，测定了各品种14个坚果品质指标，并进行了相关分析、主成分分析、聚类分析。结果表明：绝大多数坚果品质指标间相关性达到显著水平或极显著性水平；坚果品质综合表现较优的为15、6、14，品质较差的为51、40、1。15（Forkert）、6（Choctaw）、14（Oconee）可作为候选优良品种。经聚类分析16个美国山核桃品种和1个湖南山核桃品种可划分为4类，各类别间品质和遗传距离有较大差距。 |

| Abstrct : In order to evaluate nut quality of Carya Illinoensis in Jingzhou comprehensively , and
to lay a foundation of the Carya illinoensis screening varieties breeding in Jingzhou. In this paper, fourteen nut quality indexes of sixteen different Carya illinoensis varieties and one Carya hunanensis varieties were measured, the relationship between all quality indexes were analyzed by correlation analysis, principal component analysis and cluster analysis. The results showed that: the correlation of the vast majority of nut quality indexes with other reached significant level or extremely significant level; The best comprehensive performance on nut quality were 15, 6, 14, and 51, 40 ,1 were the worst.15（Forkert）、6（Choctaw）、14（Oconee）could be regarded as the candidate of excellent variety . By cluster analysisl, sixteen Carya illionoensis varieties and one Carya hunanensis variety could be divided into 4 categories, there was great gap on the quality and the genetic distance.
