This study presents the results of a three-year field experiment carried out during 2006-2008 at the Didactic and Research Station of the University of Rzeszów in Krasne near Rzeszów. The yield, its components and chemical composition of 4 lines of barley were analysed in comparison with the cultivar Rastik. Statistical analyses indicated that in the area of the Subcarpathian region are favourable conditions for growing naked barley. Of the studied lines, STH 6263, STH 6290, STH 4731 and the cultivar Rastik turned out to be the most useful for growing in this region of Poland in respect of yield. The grain of line STH 6263 contained the most protein, and the grain of the cultivar Rastic had the most fat. Functional characters of the assessed lines of barley indicate a slow breeding progress in the group of naked cultivars.
