The effect of year on grain yield and certain yield components essential for wheat yield's quality depends on agro-ecological conditions of the growing area and applied agrotechnical measures. A two-year experiment was conducted at six locations: Kikinda, Novi Sad, Pančevo, Sremska Mitrovica, Kruševac and Požarevac, using the block system, in four replications. In this study, seven winter wheat commercial varieties obtained from several seed companies were evaluated. The highest total wheat grain yield was achieved by the variety NS 40 S (8.824 kg ha-1), followed by NS Renesansa (8.817 kg ha-1), i.e. PKB Imperija (8.343 kg ha-1), while the lowest grain yield of 7.564 kg ha-1 was achieved by the variety PKB Talas. The highest average 1000 grain weight was found at Sremska Mitrovica (35,12 g), followed by Požarevac (35,09 g), i.e. Pančevo (34,98 g), while the lowest 1000 grain weight of 34,25 g was evidenced at the Kruševac experimental site.
