Abstract

New yellow-fleshed cassava genotypes are ready, highlighting the urgent need to select robust genotypes that resist diseases, thrive in diverse environments, and boost productivity for Ghanaian farmers. Nine yellow-fleshed cassava genotypes were evaluated alongside a white-fleshed reference variety in three different on-station field locations (Asuansi, Wamaso, and UCC locations) in Random Complete Block Design (RCBD) in four replications. Significant differences (p < 0.05) were found among the ten genotypes in traits like height, disease resistance, and yield. The GGE biplot analysis unveil four top-performing yellow-fleshed genotypes (12B, 1011A, 5B, 11B) consistently excelled across the Asuansi, Wamaso, and UCC locations, showing high stability and high yield potentials. It therefore recommended that these genotypes will undergo off-station field trials for validation, with the goal of introducing them as novel varieties to benefit Ghanaian farmers.
