Report of new cultivar. INIVIT B-50, new sweet potato (Ipomoea batatas (L.) Lam.) cultivar for cuban agriculture

Currently, more than 95 % of the areas dedicated to sweet potato production in Cuba are planted with cultivars from the Genetic Improvement Program (PMG) of the Research Institute of Tropical Roots and Tubers Crops. However, none of these commercial cultivars, possess the characteristics for an adequate adaptation to the variations of the climate. In recent years, the use of gene combinations has intensified through Intervarietal and interspecific crossings with the aim of obtaining progeny with genes of greater tolerance to these abiotic factors, especially to drought. The cultivar presented in this work has characteristics such as: earliness, high yield, drought tolerance, as well as flavor, texture, cooking times and nutritional values. The interaction studies-genotype environment in six different locations for two years, under conditions of water stress, allowed to define this cultivar as drought tolerant, with a yield that exceeds 4.5 t/ha to the best commercial cultivar. It is recommended to use this new cultivar in areas of the country where no irrigation is available for the cultivation.
