Selection of common cashew tree genotypes in commercial growing areas in municipalities of Piauí, Brazil

Abstract The aim of this study was to estimate genetic parameters and to select promising common cashew tree genotypes in commercial growing areas in four environments in Piauí (Piracuruca - P, Barro Duro - B, Teresina - T, and Ipiranga do Piauí - I) using the mixed model approach. Genetic variances were significant for most of agromorphological and physicochemical traits of the cashew nut and accessory fruit. The physicochemical traits exhibited more genetic variability and less environmental influence. The genetic correlations among traits were significant, positive, and of medium to high ...
