Genetic diversity in yellow passion fruit populations

The genetic diversity in yellow passion fruit genotypes from populations of different origins (Campos dos Goytacazes, Itaperuna and São Francisco de Itabapoana , Rio de Janeiro State, Brazil), was quantified. The following traits were evaluated in two environments (Macaé and Campos dos Goytacazes): fruit weight, mean number of fruits, fruit length, equatorial fruit diameter, rind thickness, brix content, acid content, juice yield. The evaluation of the genotypes cultivated in Macaé resulted in the formation of groups according to the origin of the accessions. The accessions collected in Itaperuna and in Campos dos Goytacazes performed better than those collected in São Francisco do Itabapoana. A consistent and similar pattern was observed in the analysis of the environment Campos dos Goytacazes, indicating that the accessions grown in São Francisco do Itabapoana represent genomes with inadequate traits for local producers.
