Morphological and molecular characterization of native Heliconia sp. accessions of the Amazon region

Abstract Heliconias are tropical plants with ornamental potential. These particularly used in the floriculture industry because of their exotic colors and shapes. Species characterization is important for selection genotypes plant market subsequent application studies genetic improvement. The aim this study was to estimate divergence Heliconia densiflora psittacorum accessions based on quantitative morphological molecular markers. descriptors revealed variability among evaluated. greatest observed H. accessions, whose sample number also larger compared densiflora. Morphological efficient differentiating two species, especially characteristics such as bract inflorescence length, postharvest durability, flower stem diameter, which contributed most study. On other hand, identified one individual that grouped genotypes. results showed ISSR markers can differentiate closely related individuals. materials evaluated contribute maintenance local diversity through germplasm bank breeding program plants.
