Investigations were carried out with 15 seed sources of Caesalpinia sappan assembled from Kerala and Tamil Nadu to study the seed source variation at Forest College and Research Institute, Mettupalayam. Physical characters of pod and seed expressed wider variability in the evaluated pod and seed characteristics among the evaluated 15 seed sources. Nagercoil seed source recorded the highest values on pod length. The other evaluated pod characters also expressed variability while the maximum expression was with seed number per pod and the minimum with pod width and superior variability expression with Nagercoil for pod length, Pariyaram, Kannur and Nagercoil for pod breadth, Vellanikarai (pod fresh weight), Palakkad (seed number per pod), Thalavaadi and Nallekkadu (pod to seed ratio). Variation in seed characteristics among seed sources; Pariyaram (seed breadth), Palakkad (100 seed weigth) and Pariyaram (germination per cent) recorded maximum variability for seed physical characters. However the present study expressed that the evaluated pod traits could not be achieved in a single seed sources except for 100 seeds weight.
