摘 要：
The samples were collected from the main distribution area of the Jizhaomian-Walunt,and the variation and correlativity of nut weight and three diameters were studied.The result showed that there were significant differences in Jizhaomian-Walnut fruits among and within three producing areas.The greatest variation among the three producing areas was the nut weight at 10.55 to 21.05 gram(CV was 13.44 %),followed by the nut longitudinal diameter and side diameter ratio 3.03 to 4.44(CV was 8.31 %).The nut side diameter and the nut transverse diameter ratio was 0.92 to 1.23(CV was 4.50 %) which was the smallest of all.Within the producing area,the maximal and minimal variation coefficients were still the nut weight and the nut side diameter and transverse diameter ratio.Significant linear correlation was found between the nut side diameter and transverse diameter of Jizhaomian-Walnut within different producing areas.The three nut diameters were all significantly correlated with the nut weight within every producing area.So,the nut weight was predictable.
