Effects of genotype and environment on malt beta-glucanase activity

Fifteen genotypes of barley grown in two different locations (Gonen and Bes ni) were used in this study. The malting characteristics and beta -glucanas e activities of their malts were determined. Although, malt beta -glucanase activities of the samples grown in the Besni location were much higher tha n those of Gonen samples, the malting quality of the samples from both loca tions were comparable. The results indicate that both genotype and environm ent affected beta -glucanase activity with a more pronounced effect of the latter.
