Phylogenetic tree in the form of a kinship plot. A heat map of the values in the kinship matrix, showing the level of relatedness among the population (the darker area showing highly related variety and also from different origin with the rest of the population). The population is separated into the main population (Indica) in the bigger orange box, and subpopulation (Japonica) in the smaller orange box
