Growth and nutrition in plants

The genetic diversity in yellow passion fruit genotypes from populations of different origins (Campos dos Goytacazes, Itaperuna and Sao Francisco de Itabapoana , Rio de Janeiro State, Brazil), was quantified. The following traits were evaluated in two environments (Macae 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 Macae 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 Sao 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 Sao Francisco do Itabapoana represent genomes with inadequate traits for local producers.
