Abstract

Korme and Katta soybean [Glycine max (L.) Merr.] varieties are with pedigree of AGS-129-2 and PR-145-2, respectively. These varieties were tested and released by the Bako Agricultural Research Center for Western Ethiopia and similar agro-ecological zones. Korme and Katta were evaluated for seed yield, agronomic characters and disease reaction at Bako, Boshe and Gute experimental sites between the years 2007/2008 and 2009/2010. The oil and protein contents of the two varieties were also tested. Korme and Katta soybean varieties were released because of their better seed yields as well as oil and protein contents compared to the commercial soybean variety of the same maturity group i.e. medium set. Korme and Katta were resistant to bacterial blight and bacterial pustule. The result of multi-environment yield trials showed that Korme and Katta have outperformed the commercial variety, Ethio-yogozlavia by 15 and 14% at on station and by 20 and 14% at on-farm in seed yield, respectively. The stability analysis showed that Korme and Katta were more ideal and stable in grain yield performance than Ethio-yogozlavia.
