Abstract:
Lodging strongly affects both seed yield and quality of soybean [Glycine max (L.) Merr.]. The objective of this study was to investigate lodging score of 60 soybean cultivars and analyze some traits correlated with lodging. The results showed that significant differences of lodging were found among various cultivars (P < 0.01). The correlation analysis indicated that lodging score was positively correlated (P < 0.01) with soybean stem characters, such as plant height, node number of main stem, internode length and branch number. There was a significant positive relation between stem characters and seed yield per plant, pod number per plant and seed number per plant, and also there was a negative relation between the stem characters and 100-seed weight. It was suggested that the stem characters affected both the resistance of soybean to lodging and yield. The variance analysis indicated that there were significant differences of yield characters among different lodging scores. In addition, some accessions with higher yield and low lodging score were from 2nd group of lodging score.
