Soybean yield potential can be increased by increasing the number of pods per plant, which can be achieved by increasing the number of nodes per plant while decreasing internode length to prevent lodging due to excessive height. In an effort to discover the genetic variability for this trait, a genome wide association study (GWAS) was performed on 451 diverse lines from the USDA core collection for height, internode length, and the number of nodes. The QTL signifying Dt1 was found correlating to height and quantity of nodes, but no significant QTL for internode spacing were uncovered. From our evaluation, this suggests that genomic selection for variation plant height is feasible; however, no specific genetic trait was detected to select for internode spacing.
