Abstract

The evaluation of genetic resources of native fruit species in the Atlantic Forest is essential for their introduction in conservation and genetic improvement programs. The objective of this work was to carry out the phenotipic characterization and the evaluation of genetic parameters and correlations of araçaúna, cabeludinha, jabuticabeira and uvaieira fruits accessions, collected in different locations in the mountainous region of the State of Espírito Santo, Brazil. Fruits from 44 matrices of the four species were collected in seven municipalities and were analyzed for fruit size and fresh mass and pulp, seeds and peel yield. The averages were grouped and the phenotypic correlations, heritability, genetic variation coefficient and variation index were obtained. All species have wide variability in fruit size and pulp yield. The genetic parameters confirm that most of this variation is of a genetic nature, indicating the potential for genetic gain through selection. The correlations between fruit size and mass were high, so the diameter can be used to select the heaviest fruits. The mountain region of Espírito Santo has a diversity of accessions of Myrtaceae native to the Atlantic Forest that can be used in pre-breeding works.
