Effects of Genotype and Environment on Malt β-Glucanase Activity

Fifteen genotypes of barley grown in two different locations (Gönen and Besni) were used in this study. The malting characteristics and β-glucanase activities of their malts were determined. Although, malt β-glucanase activities of the samples grown in the Besni location were much higher than those of Gönen samples, the malting quality of the samples from both locations were comparable. The results indicate that both genotype and environment affected β-glucanase activity with a more pronounced effect of the latter.
