Varieties Blesbok, Yan Shu 1, Xushu 18 and Ribbok were recommended for release in the northern Namibia. Varieties Jewel, Excel and TIS3290 performed above average under irrigated conditions at Mannheim. Varieties Excel, Kemb 10 and Nemanete were also highly promising. Varieties 1986-12-4, 1997-14-16, 1989-17-1 (Monate) and 1984-10-340 (Mamphenyane) showed average and above average performance. Varieties with good tuber yield and other agronomic criteria were selected for further evaluation.
