Fig. 2From: Identification of genetic loci associated with major agronomic traits of wheat (Triticum aestivum L.) based on genome-wide association analysisPopulation structure and diversity analysis of 287 wheat genotypes used in this study based on 30,217 SNP markers. a Population structure based on the STRUCTURE program when K = 3. G1, G2 and G3 represent each sub-population. b Δk over three repeats of structure analysis. c Kinship matrix of 287 wheat genotypes based on the TASSEL5 programBack to article page
