The study was conducted at Kulumsa, Sinana, Adet, Debra Zeit, and Holeta, Ethiopia from 2018 to 2021. The purpose of the study was to evaluate the introduced genotypes of CIMMYT and ICARDA for their adaptation, yield performance, disease resistance, and stress tolerance under the conditions in Ethiopia. The International wheat breeding programs of CGIAR centers played a crucial role in providing germplasm for bread wheat varietal development in Ethiopia. This germplasm helped in the development of new high-yield and resistant wheat varieties to overcome the recurring rust epidemic in the country and to rehabilitate the agricultural sector. The national wheat research program continued to support the country in releasing new varieties developed and field-tested through intensive research programs. These new varieties are generating reliable yields in different environments and showing excellent performance. The development of the varieties focused on their maturing groups (early, medium, and late), adaptability to different agroecological conditions, quality, and cultivation systems such as irrigation. To develop the resistant cultivar, over 8175 bread wheat germplasm from CIMMYT (6405) and ICARDA (170) sources were evaluated in Ethiopia since 2018, requested by the national wheat research programs, of which 1695 (26.46%) lines were selected from CIMMYT and 235 (13.28%) were selected from ICARDA. From the 8175 introduced genotypes, 1932 (23.63%) were selected and advanced to the next stage of cultivar development based on their combined disease resistance and agronomic traits.
