Potato playes a great role as a household food security and cash crop for many families in Ethiopia. However, lack of suitable varieties with desirable character has limited the productivity and expansion of the crop. To address this problem, two on-farm variety trials were conducted: the first in two districts, (Galessa & Meta Robi), at altitudes of 2950 and 2530 m.a.s.l, respectively, in 1999-2000 and the second in 7 districts at 28 villages in the year 2000. The objectives were to encourage farmers to participate in the evaluation and selection of varieties that would satisfy their needs and expectations; assess the performance of advanced and released varieties under farmers cropping systems; and understand attributes desired by farmers so as to establish feed back flow among researchers, extensionists and farmers in order to maximize selection efficiency. The experiments were laid out in a randomized complete block design (RCBD). Results of the first trial in relation to yield performance and reaction to late blight showd that cultivars response significantly (p0.05) varied for the parameters studied. Area Under Disease Progress Curv (AUDPC) was lower (110) for both Tolcha and Wechecha. The cultivars Menagesha and Genet out yielded others and showed a low disease incidence of 330 and 220 AUDPC, respectively. In the second trial, yield performance across locations showed that the recently released variety, Zengena (CIP-38479.6), followed by clones CIP-387412.2 and CIP-387315.2 gave a tuber fresh yield of 30.8, 27.5 and 22.4 t/ha, respectively.Farmer evaluation for boiled potatoes varied across locations. Majority of the farmers preferred clone CIP-383032.15 followed by CIP-387315.2.
