Eucalyptus grandis is one of the most planted species in Brazil due to its forestry characteristics and to its adaptation to different edaphoclimatics conditions. This makes possible significant outcomes of volumetric performance. Several origin and progenies has been studied looking to improve knowledge of the genetic structure of these populations, what makes possible obtaining the proper material to develop programs of forestry improvement in the country. The aim of this work is to make an environmental zoning by a stability, adaptability and productivity analysis from 150 progenies of eucalyptus grandis. For that, four tests of progenies were established in different places in Sao Paulo state. DAP (diameter at breast height) and trees length will be measured in all progenies tests at 12 and 24 months. The experimental delineation used was of randomized blocks with four repetitions and six plants by plot in different places. The progeny tests will be assessed by the program SELEGEN-REML/BLUP. For the stability, adaptability and productivity study of eucalyptus grandis genotypes, the MHPRVG methodology will be used (harmonic mean of relative performance of genetic values) predicted by BLUP.
