Abstract


The aim of this study was to assess phenotypic diversity in terms of fruit quality traits and yield, and also to establish valuable genotypes for breeding purpose suitable for different direction of use. Ten cultivars of hot peppers bred at VRDS Buzau were collected and fruit quality (dry matter content, fruit firmness, the total soluble solids, titratable acidity and ascorbic acid content) was evaluated at different ripening stages. A very highly significant difference (p<0.01) was found for the studied quantitative parameters, showing a great variability among the studied accessions. During ripening, the dry matter content, the firmness, the TSS content and the titratable acidity increase for all studied cultivars and there were significant differences between them. A broad range of variation was noted in Vitamin C content in both stages of maturity. In the present research work, a great variability among the studied accessions was found. Fully ripe fruits were found considerably richer in the bioactive factor than unripe fruits. Our results have selected two important genotypes: A12A, an accession suitable for obtaining chili powder, due to the his low content in dry matter and total soluble solids and accession A135 suited for fresh consumption and for long shelf life because it has a high firmness.
