An experiment was conducted during 2012-2013, in order to select better seed sources for improved genetic material and quality production of soapnut (Sapindus mukorossi). Twenty four seed sources and two D.B.H. classes from Himachal Pradesh were evaluated on the basis of fruits and seeds morphometric traits and germination parameters under laboratory condition. The study revealed significant variation among different seed sources for all traits, except seed viability where, all morphometric, germination traits in lab condition did not show distinct significant variation between D.B.H. classes. Seed sources which have higher seed weight and seed diameter showed better performance over others, those seed having lower seed weight and seed diameter comparatively. Banjar seed source was found to be superior and best, followed by Garsa seed source, for all morphometric traits over all other seed sources studied.
