Multilocational trials were conducted during 1996 and 1997 in the coastal savanna, forest and forest/savanna agroecologies of Ghana to identify early maturing sweet potato cultivars. Seven genotypes, namely TIS 8266, TIS 84/0320, TIS 86/0350, TIS 3017, Sauti, Dugbadza and Local Red (control), were evaluated in five locations and sampled for tuber yield, total biomass, harvest index, and dry matter and dry tuber yield at 3, 4, 5 and 6 months after planting (MAP). Because sweet potato is normally harvested at 4 MAP, fresh and dry tuber yields and biomass production were recorded at 3 MAP to identify the early maturing cultivars. All genotypes were identified as early maturing in both coastal savanna and forest/savanna transition zone. All genotypes, except for TIS 86/0350, were also identified as early maturing in the forest agroecology.
