Background: Common bean is an important food and export crop widely grown in Ethiopia. Limitation of high yielding and disease resistant speckled type common bean varieties with stable performance across environments is one of the factors constraining productivity of the crop in the country.
Objective: The objective of the study was to identify and release stable, high yielding and disease resistant common bean varieties for cultivation in Eastern and Western Hararghe Zones and other similar agroecologies.
Materials and Methods: Fifteen common bean genotypes along with the standard check “Tafach (SAB632)” were evaluated across four locations in 2017 and 2018 main cropping seasons using a triple lattice  design. The promising genotype, DAB-410 was selected and promoted to a variety verification trial and was tested with the standard check “Tafach” at four on-station and eight on farm sites during the 2019 main cropping season. The National Variety Release Technical Committee of Ethiopia evaluated the candidate variety in accordance with the National Variety Release Procedure.
Results: The candidate variety (DAB-410) produced an average seed yield that exceeded the average yield of the standard check, “Tafach” variety by about 23.7% and showed a stable performance across locations over the two years. The variety is resistant to rust, anthracnose, and halo blight, while being moderately resistant to angular leaf spot and common bacterial blight. It has an upright (Type II) indeterminate bush growth habit and good pod clearance. Based on the data of its performance under several environmental
conditions as evaluated the Variety Release Technical Committee and shown by its reports, the national variety release standing committee approved the official release of DAB-410.
Conclusion: “Mi’oftu” (DAB-410) showed a stable high yield performance and resistance to major diseases in the region. Therefore, the variety has been recommended for cultivation in East and West Hararghe Zones and other areas with similar agro-ecological conditions.
