Abstract:: Taking ripe fruit of walnut as material，the exterior characters of the fresh fruits from 5 walnut varieties and the nuts from 7 walnut varieties were measured during the harvest time，the exterior character of the fresh fruits，the nuts and the correlation between them were analyzed.The results showed that:there was a positive linear correlation of exterior characters between fresh fruits and nuts，it was the same relation among transverse，longitudinal and line diameter.There was a positive correlation of fresh nut weight between diameter and kernel weight like the correlation between the kernel weight and diameter，fresh nut weight，kernel rate，but it was negative correlation between the kernel weight and the thick of nuts.There was a positive correlation between nut rate and weight，longitudinal diameter，and it was negative correlation with the thick of nuts.It was a positive correlation between the thick of nuts and transverse diameter，longitudinal diameter，nut weight，nut rate，it was negative correlation with line diameter.The 5 characters of the fresh fruits was positive correlation with diameter，fresh weight and rate of nuts，it was negative correlation with the thick of nuts.The equation of linear regression and the correlation were also being present.
