Sweet potato is a vital food security and income generation crop in Ethiopia. This study was conducted to evaluate the performance and adaptability of six white-fleshed sweet potato varieties (Hawasa- 09, Barkume, Tola, Adu, Hawasa-83, and a Local check) across three districts (Gechi, Bedele, Dabo) in the Buno Bedele Zone in 2023 to 2024 cropping seasons. A randomized complete block design (RCBD) with three replications was used. Collected data including days to maturity, root length, root diameter, number of roots per hill, Marketable root yield, Unmarketable root yield, Average root weight, and total root yield. The combined data were analyzed using SAS and Genstat 18 statistical software. Analysis of variance revealed highly significant (p<0.01) differences among varieties, locations, and years for most traits. The Additive Main Effects and Multiplicative Interaction (AMMI) analysis further quantified a significant genotype-by-environment interaction, with the environment explaining 63.16% of the total variation. Hawasa-09 and Tola were identified as high-yielding and stable varieties across test environments, with mean total root yield of 54.71 and 47.18 t ha^-1, respectively. In contrast, Hawasa-83 (39.57) and the Local (39.73 t ha^-1) varieties showed consistently lower yields. The study concludes that Hawasa-09 and Tola were well-adapted to the agro-ecologies of Buno Bedele Zone and are recommended for demonstration and dissemination to enhance productivity and food security.
