Description
Summary:The aim of this study was to estimate genetic parameters and select superior mango genotypes using the mixed-models approach. The 16 genotypes, varieties and hybrid selections, were evaluated regarding physical and physical-chemical traits of the fruit using the REML/BLUP methodology. Mango fruit weight and pulp weight can be selected indirectly based on fruit length and diameter, which are more easily evaluated. The hybrids CPAC 26394, Lita, and Rosa 46 stand out in regard to fruit size. The genotypes R12P09, CPAC 2293, Roxa, Omega, Alfa, and Lita have better quality fruit than the Tommy Atkins variety that is widely used in commercial orchards. The Roxa variety has pulp with little or no fiber, a trait that is of great importance to consumers and for industrial processing. The genotypes Alfa, CPAC 5895, Omega, R10P08, R12P09, R13P10, Rosa 2, Rosa 36, and Rosa 46 have pulp free of internal breakdown. The varieties and hybrid selections of mango show variability regarding fruit traits, and the REML/BLUP methodology is efficient for selection of genotypes with desirable fruit traits in mango.

Objetivou-se estimar parametros geneticos e selecionar genotipos superiores de mangueira, utilizando a abordagem de modelos mistos. Os 16 genotipos, variedades e selecoes hibridas, foram avaliados quanto aos caracteres fisicos e fisico-quimicos do fruto, utilizando a metodologia REML/BLUP. A massa do fruto e a massa da polpa de mangueira podem ser selecionadas indiretamente com base no comprimento e no diametro do fruto, que sao mais facilmente avaliados. Os hibridos CPAC 26394, Lita e Rosa 46 destacam-se quanto ao tamanho do fruto. Os genotipos R12P09, CPAC 2293, Roxa, Omega, Alfa e Lita apresentam frutos de melhor qualidade do que a variedade Tommy Atkins, bastante utilizada em pomares comerciais. A variedade Roxa apresenta polpa com pouca ou nenhuma fibra, caracteristica muito requisitada por consumidores e para processamento industrial. Ja os genotipos Alfa, CPAC 5895, Omega, R10P08, R12P09, R13P10, Rosa 2, Rosa 36 e Rosa 46 apresentam polpa livre de colapso interno. termos de indexacao: Mangifera indica L, herdabilidade, correlacao genetica, ganho genetico.
