Abstract:
We have studied the agronomic, yield and quality traits of 151 soybean accessions for 2 years and analyzed with the method of ANOVA, correlation and cluster analysis. The results showed that the coefficient of variation (CV) of germplasm of soybean based on phenotypic traits were 6.50%-52.03% and 6.71%-50.90%, respectively.Agronomic traits and production were significantly different between cultivars except for number of seeds per pod.The results of correlation analysis indicated that yield correlated significantly positively with all phenotypic traits except effective branch number and protein content.The results of principal component analysis of 14 traits suggested that these traits might be reduced into 4 comprehensive indexes (yield traits factors, growth factors, grain weight and adipokines factors, plant type and protein factors), whose cumulative contribution rate accounted for 78.088%, reflecting basically the growth, yield and quality status of soybean.
