Abstract

The main objective of this research is to determine the qualitative - technological properties at domestic two row winter barley genotypes. The field trial of this study was conducted on the experimental area "Uniservis Agro" in two locations, Ovche Pole and Strumica, during two years (2012-2013 and 2013-2014). The experiment was set up according to the method of random block system in three repetitions for each genotype and locality by applying standard agro-techniques for barley. As experimental material were used five domestic two row winter barley genotypes. Three of them are registered varieties (Hit, Izvor and Egej) and two are promising lines (Line 1 and Line 2). Barley genotypes were analyzed for the following qualitative - technological properties: protein content (%), grain uniformity from I class (%), water sensitivity (%), the degree of soaking (%), the weight of 1 000 grains (g ) and hectoliter mass (kg/hl). The content of protein was determined by content of total nitrogen using the method of Kjeldahl, while determining the grain uniformity from the I class, water sensitivity and degree of soaking were done according to the standards of the European Convention for the production of beer. Hectoliter mass was determined by standard ISO 797. The results of the analysis of qualitative - technological properties were statistically processed with statistical package (Stat Soft, 8.0). Besides descriptive statistics, data of these properties were analyzed by the method of cluster analysis (Cluster Analysis, CA), in order to establish the connection or the distance of the tested genotypes based on qualitative - technological properties. Generally, in both locations, obtained average dates for all qualitative - technological properties for all genotypes, average for the period of study, were in the optimal limit values, with exception of protein content, which in all genotypes was above 12 %. Genotypes Line 1 and Line 2 were singled out with the best qualitative - technological properties in both localities, but good grain quality also proved genotype Izvor analyzed in Ovche Pole locality. By applying the cluster analysis, based on the qualitative - technological properties, we got that all analyzed genotypes in both localities were closely interconnected, differentiated in one cluster, with the exception of genotype Line 1, grown in Ovche Pole locality. Key words: grain quality, technological properties, barley, genotype
