Use of the REML/BLUP methodology for the selection of sweet orange genotypes

Abstract: The objective of this work was to select superior sweet orange (Citrus sinensis) genotypes with higher yield potential based on data from eight harvests, using the residual or restricted maximum likelihood/best linear unbiased prediction (REML/BLUP) methodology. experiment carried out 2002 2008 and in 2010 municipality Rio Branco, state Acre, Brazil. Analyzes deviance were performed test significance components variance according random effects used model, parameters estimated individual genotypic phenotypic variances. A selection intensity 20% adopted regarding selection, i.e., only best 11 55 tested selected. estimates genetic show existence variability studied genotypes. correlation between harvests is low magnitude, except for variable average fruit mass, and, as a reflex, there change ordering Genotypes 5, 48, 19, 14, 47 stand being most productive, therefore, are suitable purposes. 14 performance character set evaluated.
