Malt quality traits of barley cultivars grown at the Agricultural Institute Osijek

Grain and malt traits important for malting quality were studied on a set of 6 barley genotypes grown at location of eastern Croatia for three seasons (2009, 2010 and 2011). Malting of samples was done with Joe White automatic micro-malting system. Statistically justified differences in results of malt extract content and wort viscosity were found both between cultivars and years. Malt extract content varied from 74.88% (Osk.5.161/3-06 in 2010) to 80.60% (Lukas in 2009). The results of determination of wort viscosity ranged from 1.4765 mPas (Vanessa in 2010) to 2.4994 mPas (Bravo in 2009). Regarding the results of the analysis of friability and Kolbach Index data observed, there were also statistically significant differences between cultivars and years included in this study. Significantly higher friability means were noticed in cultivar Vanessa (60.36%) and in 2009 year (54.47%). Cultivar Lukas resulted in significantly higher Kolbach Index (37.07%), while the year 2010 resulted in significantly lower mean of Kolbach Index (34.46%).
