摘要
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 g 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.
