Abstract
"Serie INIVIT Dorada", comprising three sweet potato cultivars 'INIVIT Dorado-2', 'INIVIT Dorado-4' and 'INIVIT Dorado-6', is presented. These genotypes were developed through controlled hybridizations between elite parents of Chinese, Peruvian and Cuban origin. The genotypes were selected through a recurrent selection scheme that included evaluation in F₁ and C1 generations, and multi-environment trials across 13 locations in Cuba. The cultivars exhibit uniform elliptical-shaped roots, smooth skin, absence of morphological defects, homogeneous size (200-400 g), and orange flesh with high β-carotene content (>450 ppm). Additionally, they show excellent phenotypic stability and adaptation to Cuban edaphoclimatic conditions.
