Breeding programs has been established toidentify genotypes with high yield potential for use incomrnercial plantations and development of interspecifichybrids. The aim of this study was to estimate thegenetic divergence among progenies of P. elliattii fromsilvicultural traits (DBH,height, and volume) evaluatedfrom the first to the fourth age. A trial established inPonta Grossa, Paraná, Brazil, in 2009. This experimentwas carried out in a randomized complete blockexperimental design with 25 treatments (progenies)32 blocks, and one plant per plot at a spacing of 3.0 x3.0 meters. The divergence between progenies wasperformed by distance matrix of Mahalanobis. Based onthese values, progenies were grouped ínto clusters usingTocher's method. Estimative of genetic divergence,using a multivariate analysis, showed a pattern of ninegroups. The majority of progenies was grouped in thefirst one (I) (54.17%)followed by groups Il, III, IV (8.33%)and V, VI, VII, VIII, IX (4.17%). The most productiveindividuaIs of genetically divergent groups they can beused to controlled crossings to produce highly productiveindividuaIs.~~-------------------------------------
