Yield Stability of Ground Nut (Arachis hypogaea L.) Genotypes in Low Lands of Western Oromia, Ethiopia

Solomon Bekele


In plant breeding, selecting the stable genotypes is very important; specially, for wider adaptability. Until now, there was no single improved ground nut variety released for western parts of Oromia; however, Kulki and Shulamiz varieties released nationally were adapted for the area. Fourteen ground nut genotypes have been tested through reargues breeding trial since last five years at Bako Agricultural Research Center to release the first variety (ies) that have higher yield and disease resistant and adaptable and productive for western parts of Oromia. Regional variety trials and variety verification trials of 14 genotypes were evaluated against standard check Bulki at three locations, Chewaka, Uke and Gutin. Candidate variety ICG-9097 and BARBARTON have got 21.2 % and 9.6% yield advantages over standard check Bulki and they showed more yield stability   than the rest tested genotypes and they were also showed resistant to late and early leaf spot disease during 2015-16. The national variety releasing committee evaluated the candidate and waiting for decision of standing committee for possible release.
