Abstract

This work aimed to study the interaction between genotypes and environments, using the BLUP/REML procedure for evaluation of precocious cashew clones. The purpose of this work was to identify genotypes that simultaneously aggregate high productivity and genotypic adaptability and stability. The experiments were set up employing a complete block design, with eleven treatments, three repetitions and five plants per plot. The results showed an alteration in the clone order, in the different environments, as reflected from the genotypic correlation of average magnitude (0.58). The heritability of clones presented moderate to high magnitude for the different traits, indicating excellent possibilities for selection, allowing selective accuracy of 83%. The methods MHVG, PRVG, and MHPRVG can be part of selective criteria in the cashew breeding program.
