Registration of Bubu, a Medium Maturing Improved Potato (Solanum tuberosum L.) Variety for the Eastern Highlands of Ethiopia
Abstract
An improved potato (Solanum tuberosum L.) variety, Bubu (CIP-384321-3), is developed by the Root and Tuber Crops Improvement Program of the Haramaya University, Ethiopia and approved by the National Variety Release Committee in 2011. The performance of the variety was evaluated at five locations in the eastern part of Ethiopia from 2006 to 2009. The mean performance of Bubu over locations and years indicated that it gave 11.5% more tuber yield over the standard checks (Harchassa and Gabissa). Although it is not stable for tuber yield, it exhibited high sensitivity to environmental change and a better adaptation to high-yielding environments. Bubu is a medium maturing variety with tuber size and shape preferred by the farmers. The taste of boiled tubers was rated as very good by the farmers. The variety is recommended for the highlands of Eastern and Western Hararghe Zones with an altitude ranging from 1650-2330 meter above sea level.
