Estimated population structure of 44 pigeonpea genotypes.
(a) Average of likelihood value L (K) (mean + SD) against probable number of clusters (K). (b) Barplot of subpopulations at K = 4. Each genotype is represented by a vertical bar and partitioned into colored segments which represent the estimated probability membership in each of the K-inferred clusters on the y-axis. Bar colors (red, green, blue and yellow) indicate the groups identified through the structure program.
