With the aim to evaluate grain yield and selected malting quality traits in spring barley genotypes, 17 new barley genotypes and three control cultivars (Xanadu, Nitran, Slaven) were evaluated in the year 2009 on five localities (Borovce, Sládkovičovo, Spišská Belá, Solary, Trebišov). In grain yield, significant effects of genotype, locality, and their interaction were found. No genotype with significant higher grain yield compared to controls was found. In protein and extract content (analyzed in narrow set), significant differences were among localities and genotypes, with higher variability in protein content. Nearly half of evaluated genotypes had higher starch content, but only two of them were comparable in amylose content with control cultivar Nitran. beta-amylose content provided good possibilities for selection, as nine genotypes had above average values. Beta-D-glucan content was higher, however three genotypes were detected with its lower content. Spring barley genotypes combining high grain yield and at least two positive malting quality traits were found and recommended for next phase of evaluation in the breeding process.
