(a) Correlation network illustrates the relationship of 27 quantitative descriptors with five geographic population. Each node represents 5 geographic population of BG with five defined color and each edge represent the correlation between the two traits. (b) Pattern search plot insight into the correlation abundance of top 25 traits of respective five (1 = Gombe; 2 = Kwami; 3 = Akko; 4 = Sokoto; 5 = Alkaleri) Bambara ground nut population.
