Abstract

Sweetpotato is cultivated in all the regions of Côte d’Ivoire for consumption and as a source of income. Only varieties with white or yellow flesh are grown. Production of nutritious orange-fleshed sweetpotato (OFSP) is hampered by the lack of genetic resources and planting material. To evaluate and release OFSP varieties, on-farm demonstration tests were conducted with women farmer groups in Bondoukou, Nassian, Korhogo and Bondiali in the north and northeast Côte d’Ivoire. Six varieties- ‘Kabode’, ‘Kakamega7’ (‘Irene’), ‘Tacha’, ‘Bela Bela’, ‘Vita’ and TIB-440060-were evaluated in comparison with locally grown varieties. The on-farm demonstration was laid out in a randomised complete block design with replicated three times per location. Assessments were made on yield, disease and pests; and consumer preference on attractiveness of skin color and flesh of the root (fresh and boiled), taste, texture and starchiness. Results showed that introduced varieties have generally recorded higher yields than the local varieties: Yields of about 25 t/ha have been recorded on the sites. The best average yield of about 15 t/ha, was recorded for TIB-440060 and ‘Irene’ varieties. Farmers’ acceptance of OFSP varieties based on the attraction of their color, the dry matter content and taste was more than 90%. At the end of the sensory tests, ‘Irene’, which achieved the best compromise between all observed and measured parameters, was most appreciated and was the farmers’ first choice, followed by varieties TIB-440060 and ‘Bela bela’.
