Polycross-derived orange-fleshed sweetpotato (OFSP) genotypes have importance for exploitation as they originated from a broad set of parents.  This study included nine selected genotypes and was conducted in three locations where moisture stress was known to be a major challenge to crop production. Food security in these areas relies heavily on evaluating and identifying resilient and nutritious crop varieties. The experiment was conducted in a randomized complete block design with three replications. Key parameters such as root yield, vine length, root length and girth, sweetpotato viral disease reaction, and root dry matter content were measured to determine adaptability and their yielding potential. The results revealed significant variation in the main effects of genotype and location, as well as significant interactions for most yield and yield-related traits, with two genotypes, G2 (MUSG014012-26-4-16) and G8 (MUSG014001-3-2-40), consistently outperforming the check variety, Kabode, with yields of 28.9 and 26.4 t/ha, respectively, representing over 90% higher yields over the check. These two genotypes can help improve food and nutrition security in drought-prone regions. As a result, newly identified genotypes G2 and G8 can serve as the best varieties for further recommendation in study areas and similar agro-ecologies characterized by low moisture stress and erratic precipitation, which challenge crop productivity.
