Abstract:

In this study, we analyzed the variations between seed yield and quality at each node in soybean with different growth habits. Using indeterminate soybean Yuanbaojin and Jinyuan 1£¬ semiª²determinate soybean Jinong 7 and Jilin 45 as experimental materials, the yield, protein content and fat content at each node were tested. The results indicated that the yield, protein content and fat content at each node of all tested cultivars were different. Yuanbaojin and Jinyuan 1 had higher yield at middle layers, higher protein content at upper layers, and higher fat content at lower layers. Jinong 7 and Jilin 45 had higher yield and protein content at upper layers, and higher fat content at middle layers. The yield and protein content were significant positive correlated at upper layers, and the yield and fat content were highly significant positive correlated at upper layers in Jinyuan 1. The yield and protein content and fat content had highly significant positive correlation at lower layers in Jinong 7. The yield and protein content and fat content had significant positive correlation at lower layers in Jilin 45. The result could provide theoretical basis for the reasonable use of seed at each node and the improvement of the relationship between yield and quality in soybean.
