Fruit Characters Variation of Ribes mandshuricum
摘要
Abstract
The correlation between growth and fruit characters of Ribes mandshuricum and its variation charac-teristics among natural populations and individuals was studied based on variation analysis, nested analysis of vari-ance, 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 compo-nents analysis, 13 characters of R. mandshuricum could be divided into two groups so that calculate the main com-ponent 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.关键词
