Abstract

Brazil forest sector is international featured because the high productivity obtained with some exotic species, mainly eucalypts species. Eucalyptus urophylla is the most important specie nowadays in Brazil. The aim of our study is to build a new breeding population by grouping progeny/provenance materials from advanced generation of improvement available in two experimental networks in Brazil, creating a new breeding population with wide genetic base. To achieve this goal it will be done a study of stability and adaptability (ecological zoning) in both experimental networks; and a comparison by molecular markers of genetic diversity in advanced populations with base populations from different origins of the E. urophylla. It will be possible to obtain genetic diversity, genetic distance, population differentiation, fixation index and relationship coefficient within population and compare theses variable among base and advanced breeding populations. Molecular analysis of commercial clones, in order to check the origin of clones, will be included. These results will drive the new breeding population of the most important exotic forest species in Brazil. (AU)
