Abstract: The correlation between growth and fruit characters of Ribes mandshuricum and its variation characteristics among natural populations and individuals was studied based on variation analysis, nested analysis of variance, multiple-comparison, correlation analysis and principal component analysis, 60 individuals which selected from 4 different natural populations were took as test sample.Results show that the average variation coefficient of each character was 21.95%, the variation range was 5.15%-30.64%.There were significantly differences between 5 nutrition characters within R.mandshuricum populations, and 3 nutrition characters showed extremely significantly differences within R.mandshuricum populations.The mean phenotypic differentiation coefficient of all characters was 22.56%, and the variation between populations (21.81%) was lower than that within populations (74.87%).There was significantly extremely positive correlated between most fruit characters.According to principal components analysis, 13 characters of R.mandshuricum could be divided into two groups so that calculate the main component score for fast and accurate selection while cultivating superior individuals of different economic objectives.In a word, The fruit characters phenotypic differentiation of R.mandshuricum natural populations was moderate level.The main variation was within populations.
