Abstract
Ethiopiahas suitable environmental condition for potato production. However, the productivity of potato is very low as compared with world average due to lack of stable, high yielding, and disease resistant cultivars. Therefore, the objective of this study was to evaluate the promising genotypes and verify the most stable, high yielding and disease resistant potato genotype for highlands of Bale. For the study, the experiment was carried out at three locations from 2009 to 2011 production seasonusing 11 genotypes including local and standard checks. Randomized complete block design with three replications was used for the experiment. One of the experiments was conducted at the research farm of Sinana Agricultural Research Center, Oromia Agriculture Research Institute, Sinana and the others at the farmers’ field, Dinsho and Shalo. The study found that the Milki (CIP-394640.539) varietyhad above average yield performance in most test environments, out yielded the Jalane, Ararsa and Hunde. The average tuber yield of Milkiover locations and over years is about 49.31 t/ha. It has also better yield stability than checks. Milkiis, therefore, released in 2012/13 for production for all potato growing environments in the highlands of Bale and other similar agro-ecologies.
