Analysis of Grain Yield and Cytolytic Degradation of Winter and Spring Barley Cultivars.

Six barley cultivars were grown in locations of Osijek and Nova Gradiska (Croatia) for three successive years. Our study included cultivars of different seasonal type. 'Zlatko', 'Barun' and 'Vanessa' are two-rowed winter type barley cultivars and 'Fran', 'Matej' and 'Scarlett' are spring barley cultivars. The results of grain yield and cytolytic degradation showed significant differences among winter and spring cultivars under different growing conditions. Winter type cultivars 'Zlatko' and 'Barun' showed significantly higher grain yield in comparison with other cultivars. Generally, spring barley cultivars when compared with winter cultivars had significantly higher malt extract content, lower malt extract fine-coarse difference, lower malt viscosity, higher β-glucanase activity and lower malt β-glucan content, higher friability.
