Abstract
The study was conducted at three locations (Chosha, Yelagnaw Arguba and Zazie) for two consecutive years. It was carried out to evaluate and select high yielding, potato varieties for study areas and areas with similar agroecologies. The experiment consisted of eight potato varieties (six released varieties and two local checks). The study was conducted using a Randomized Complete Block Design with three sets of repeated measures. The combined analysis of variance showed that there was statistically significant difference among environments, among varieties and significant effect of GEI on phenology and growth parameters, tuber yield and its components. But there was non-significant effect of GEI for days to emergence. The same was true with weight of non-marketable tubers ha-1. This revealed that the environments were diverse, and confirmed differential performances of varieties across locations. The greatest potato harvest was achieved at the Yelagnawarguba site (34.16t ha-1) and the lowest yield was obtained at Chosha (24.53t ha-1). Variety Belete (42.84t ha-1), Horro (35.29t ha-1), Gudanie (34.56t ha-1), Asmara (30.58t ha-1) and Jalenie (30.56t ha-1) gave above average tuber yields (28.73t ha-1), while Araarsaa gave the lowest tuber yield (14.20t ha-1). Thus potato varieties tested for their adaptability were relatively higher except Araarsaa and Hundee. Therefore, these varieties were suggested for expanded cultivation in the study regions and in regions with comparable agroecologies.
