In 2017/2018, experimental results at CIP-Headquarters showed genetic gains for root yield of between 70% and 118% over the baseline breeding populations selected for wide adaptation, earliness, high iron content, and non-sweetness. In Uganda, based on the performance of 1,600 crosses for three seasons (2016-2017), 48 cross combinations were identified to generate progenies with sweetpotato virus disease (SPVD) field resistance. In Mozambique, two promising clones have good combinations of beta-carotene, iron and zinc, and with annual increments of 0.166 to 5.91 mg/100g (dwb) in the three traits.
