We selected 28 popula.ions of Leuca.na.leucocepha.a.from different geogra.hica. loca.ions in the sta.es of a.dhra.Pra.esh, Ta.il Na.u a.d Orissa.of India.on the ba.is of height a.d girth a. brea.t height （GBH）. We eva.ua.ed fiber length, optica. density, wa.l thickness, vessel element length, vessel element dia.eter, specific gra.ity a.d lignin of these popula.ions of L. leucocepha.a.in different sites. Popula.ions ha. significa.t va.ia.ions for a.l growth, wood a.d pa.er pa.a.eters. Girth a. brea.t height （GBH） a.d specific gra.ity were the most importa.t pa. ra.eters for herita.ility a.d genetic ga.n, respectively. The minimum herita.ility wa. reported for vessel element length a.d genetic ga.n for fiber length. The popula.ions were grouped into six clusters, cluster II ha. ma.imum number of popula.ions （14） a.d clusters IV a.d VI ha. one popula.ion ea.h. GBH contributed ma.imum of 34.39 % towa.ds tota. divergence followed by specific gra.ity （14.02%）. a. economic technique to produce qua.ity seed by esta.lishing seed orcha.ds with genetica.ly divergent pa.ents wa. suggested.
