The objective of this study was to determine the correlation between yield and its components and their direct and indirect effects on grain yield in two-row winter barley varieties. The experimental work was conducted during the period of 2012-2014 on the research fields of the Faculty of Agriculture, in two different areas in the Republic of Macedonia, Ovche Pole and Strumica. As far as material is concerned, 21 genotypes were used with Macedonian, Serbian, Croatian and Bulgarian origin. Significant and positive coefficient of correlations were obtained between grain yield and number of spike per m2, number of productive tillers per plant and grain weight per plant, number of grain per spike and grain weight per spike, grain weight per spike and 1000 grains weight in both localities. The highest direct effect to grain yield was obtained by number of spikes per m2 in both localities. Therefore, this trait can be used as a criterion in breeding to improve the yield of barley varieties. Keywords: correlation, yield, path coefficient analysis, barley
