. "Study introduces the evaluation of root system size (RSS) for the breeding of barley, in particular for drought tolerance. In 2007--2009, about 20 varieties of spring barley (Hordeum vulgare L.) were evaluated at two locations (only one in 2007) for RSS by its electric capacity. A significant correlation between electric capacity of the root system and its weight, volume and root surface was found. RSS was compared with yield and quality of the varieties in state registration trials. Varieties with greater RSS than the other varieties had a significantly higher yield in the dry year of 2007. Similar relationships between RSS and yield in the other years were found in only some of the environments. Malting varieties with greater RSS had significantly higher contents of starch, saccharide extracts and malt extracts, as well as higher yields of protein and starch in 2007. It can be concluded that lower RSS is related to low grain yield and malt quality in dry environments, even in genetically diverse varieties. The results indicated that higher yields of barley correlated with greater RSS in dry environments. The response of plants to drought was similar to the response of the plant to the possession of small RSS and was evidenced in lower starch content and higher nitrogen content in barley grain."@en .
