Population structure analysis of the NWDP. a Estimated population structure of 318 spring wheat genotypes from Nepal on K = 4. Columns represent individual wheat accessions, while the length represents the proportion of each subpopulation (indicated by the colour) belonging to that accession. b Dendrogram based on cluster analysis using pairwise genetic distances. c Principal component analysis (PCA) using 95 K GBS markers. The labels SP1, SP1, SP3 and SP4 correspond to the subpopulations 1, 2, 3 and 4
