Abstract: The aim of the present study was to evaluate agronomic characteristic of advanced mutant lines winter malting barley and possibilities for their direct use as cultivars or as parents in the breeding program. The study was carried out at the Institute of Agriculture, Karnobat, Bulgaria in the period of 2011-2013. Mutant lines 73/1994/06 and 525/08 had a significantly higher grain yield and a complex of valued agronomic traits and they can be used in a breeding program of winter malting barley for yield improvement. The lines 362/8663 and 129/2291 showed good malting quality. Significantly high yield and grain quality of line 67/1791/06 makes it suitable for further testing as a candidate variety.
