Abstract

The objective of this work was to perform a morphoagronomic characterization of the papaya accessions of the active germplasm bank (AGB) of Embrapa Mandioca e Fruticultura, through the study of genetic diversity and multivariate analysis. Ninetytwo papaya accessions were characterized in 92 accessions of the papaya germplasm, using 20 descriptors, from which 9 were related to quantitative traits, and 11 related to qualitative ones. A descriptive analysis of the quantitative traits was performed, from which accessions with 20 °Brix soluble solids and 5.5 kgf cm-2 fruit firmness stood out. The multivariate analysis of the 20 descriptors resulted in the formation of three groups. The accessions showed moderate diversity. The accessions CMF006, CMF054, CMF056, CMF067, CMF072, CMF082, CMF115, CMF131, CMF188, and CMF204 stood out for soluble solids, fruit firmness, pulp fibrosity, plant height, and height of the first fruits. Equally distributed in the ‘Formosa’ and ‘Solo’ groups, these most accessions originated from Brazilian cultivars. Despite the narrow genetic basis of papaya, the study showed a moderate diversity and an important genetic variability in accessions of agronomic interest. Therefore, the papaya ABG of Embrapa Mandioca e Fruticultura can meet the demands for genetic improvement and the expectations of farmers.
