Abstract

The bread making quality of Ethiopian cultivars was studied using 18 quality traits at low and high protein environments. Significant variation was observed between genotypes with a broad range of milling, rheological and baking traits. Three different quality prediction models were constructed explaining 48% to 73% of the variation of mixing time and loaf volume, respectively. SDS-sedimentation alone accounted for 56% of the variation in loaf volume at the high protein environment. The variation of mixing time due to protein content alone was 37% at the low protein environment. SDS-sedimentation and mixograph mixing time were common in the three models. SDS-sedimentation, protein content and mixing time can be used as selection criteria in breeding programs where resources are limited. Hectoliter weight and grain weight also contributed to the variation of loaf volume and mixing time.
