Abstract:
Six white fleshed sweet potato varieties were tested in Gamo zone of southern region, Ethiopia in 2019 and 2020 to evaluate their total root yield potential and demonstrate best performing varieties. The experiment was laid out as a Randomized Complete Block Design with four replications. The combined analysis of variance showed highly significant differences among genotypes on growth, root yield and its components. The maximum number of marketable roots per plot was recorded on variety Hawassa -09 (70.25) whereas minimum number of roots per plot was recorded on ADU (11.00). The highest root yield per hectare was obtained from variety Hawassa -09 (62.16 ton ha-1) followed by Tola and Berkume (53.99 and 52.85 ton ha-1), respectively. The lowest root yield per hectare was recorded from variety ADU (5.21 ton ha-1). Based on the result of this study from six evaluated white fleshed sweet potato varieties Hawassa -09 was recommended for pre extension demonstration at the area and similar agro ecological locations.
