Abstract:
In order to know the correlation of density tolerance traits and yield under different densities on soybean, 150 soybean germplasm resources were used to analyze the interactive relationship between different traits and yield under high density and conventional density. The results showed that there were significant or extremely significant positive correlation between plant height, main stem node number, center of gravity height and lodging rate. The correlation of available primary branches was extremely significant negative with center of gravity height and lodging rate. The correlation of yield and lodging rate was extremely significant negative and the indirect correlation factors come from the center of gravity height and plant height. The correlation of available primary branches and yield was extremely significant positive and the indirect correlation factors come from the center of gravity height and lodging rate. So the most relevant traits of yield were the lodging rate,the center of gravity height and the available primary branches. The results provide theoretical basis and excellent materials for the innovation of densi-tolerant soybean varieties.
