Bread wheat breeding objectives in Ethiopia include high yield, disease resistance, tolerance to stress environments, resistance to lodging and shattering, and grain quality. The major sources of germplasm introductions are CIMMYT/Mexico and CIMMYT/ICARDA/Syria. In 1997, six nurseries consisting of nearly 700 entries were introduced and evaluated under quarantine at Hotel Research Center, a hot- spot for Septoria tritici. Resistance/tolerance to septoria leaf blotch, yield potential and agronomic appeal were the major factors in screening the materials for high rainfall areas. Septoria, however, is not a major factor in evaluating genotypes in semi-arid nurseries. After field evaluation and scoring, seed selection was used to scrutinize and advance promising materials. Based on different criteria used in screening, about 31% of the introductions were promoted to the next testing stages under different environments.
