Abstract

[...]variation in branch number among soybean cultivars of diverse origins under low-density planting suggests the presence of genetic differences [6,7]. [...]breeding for soybean genotypes with optimal plant architecture adapted to a specific planting density is necessary for improving yield and enabling mechanical harvesting. The log likelihood (LnP(D)) from STRUCTURE [18] analysis showed a continuous increase with the number of sub-populations (K). [...]we determined the optimum K value using the ∆K method. Determination of Genetic Association with Branch Numbers Using GWAS To determine the best fitted GWAS model for branch numbers, quantile–quantile (QQ) plots generated using the generalized linear model (GLM) + population structure (Q) were compared with those generated using the mixed linear model (MLM) + Q (from principal component analysis; PCA) and kinship matrix (K) (Figure S3). The GLM + Q model showed a strong inflation of p-value (blue dots) compared with the MLM + Q (PCA) and K model (red dots), indicating erroneous inflation of false-positive signal. [...]MLM + Q (PCA) and K model was more appropriate for the identification of QTNs associated with branch numbers in this study.
