Variation and Associations of Quality Parameters in Ethiopian Durum Wheat (Triticum turgidum L. var. durum) Genotypes

A. Mohammed, B. Geremew and A. Amsalu
Knowledge on variability and quality of durum wheat genotypes for pasta making as well as associations among quality parameters is important to design a suitable plant breeding program. Sixteen durum wheat genotypes were tested at Sinana and Adaba, Southeastern Ethiopia during 2009 bona season. The experiment was laid out in a randomized complete block design with three replications. Thirteen quality parameters were included in the study. Pooled analysis of variance revealed significant differences among genotypes for all quality parameters studied indicating the presence of variability. Genotypic correlation coefficient depicted important quality parameters are positively correlated with grain protein content, suggesting a common genetic basis among these traits and indicating the possibility of simultaneous improvement. Yellow pigment content showed the highest heritability value of 84.3% and gluten index had the lowest value of 3.8%. Dry gluten content (0.65**) and thousand kernel weight (0.26*) had the highest positive direct effect on grain protein content and significant positive genotypic correlation with grain protein content. Hence these traits are important as selection criteria for improvement of grain protein content in durum wheat. Protein content of the genotypes ranged from 10.7% (CDSS94) to 13.2% (Leliso). The study also showed variations in gluten strength as measured by alveograph strength W ranging from 64.3x10-4 J (Gerardo) to 187.6x10-4 J (Hitosa). Considering the performance of genotypes across most quality parameters, all the studied genotypes except Gerardo, Oda and Cocorit-71 were superior and could also serve as donor sources in durum wheat breeding programs for good pasta making quality.
