Sažetak
With a total of around 180 milion ha worldwide, barley is in fourth place in the world crop production and is therefore a significant product in the marketing of agricultural commodities. In Serbia, the area sown to this crop is about 125,000 hectares and rising. Using breeding and adequate production technologies, domestic barley growers are trying to provide barley that will meet the demands of the malt and beer industry and livestoch feed plants in terms of yield and quality. The environmental conditions in Serbia are specific precipitation- and temperature-wise, so a barley genotype needs to be bred whose dynamics of growth and development will be best adapted to the growing conditions in question. The present paper discusses the basic parameters of barley yield and quality and the possibility of their improvement by breeding. The 1000-kernel weight is a highly important parameter in breeding malting barley for yield and technological quality. Malting barley should have a lower protein content, forage barley a higher one, while the levels of beta-glucans should be as low as possible in both types. Malting barley should produce malt with a high extract content and a good level of cytolytic, proteolytic, and amilolytic degradation. As a high a resistance to prevalent diseases and stress conditions as possible is also advantageous to any high-yielding, high-quality cultivar of barley.
