Análise univariada e multivariada em progênies de Eucalyptus camaldulensis Dehnh em Mato Grosso

Abstract

The Eucalyptus camaldulensis Dehnh stands out between the species of the genus, due to the wide plasticity and their multi-products. The success of the genetic improvement program depends of the available germplasm, environmental factors and methodologies selection. The present study was estimate to evaluate the genetic variability and diversity to 132 progenies of Eucalyptus camaldulensis using analyze the univariate and multivariate methods, installed in the Santo Antônio de Leverger region - Mt, located in the Serra de São Vicente. Such a way were used methodologies to assess genetic variability through genetic parameters and a grouping techniques. The work was divided into chapters. In the first chapter were used the analysis univariate to evaluate the genetic parameters and the gains with the selection. The results indicated genetic variability for the analyzed characters in particular to DAP. The higher genetic gains were found through the individual selection when compared among the selection between and within. So, these results are important for the sequence of the improvement of the specie in the studies amount area in Mato Grosso State. In the second chapter were used the multivariate analysis for determining the genetic divergence between progenies for a groups methodologies, through the distances Mahalanobis and the Euclidiana. The results proved more effective for the progenies allocation in various groups, just as well for the select progenies classification, facilitates the strategies of the genetic improvemnet of the specie.
