Evaluation of varieties and hybrid selections of mango in the brazilian semi-arid region.

Evaluation of varieties and hybrid selections of mango in the brazilian semi-arid region.

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, Ômega, 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.
