This paper presents the results of winter barley cultivars (Rekord, Grand, NS 565 and Nonijus). Varieties were grown in the experimental field of Agro-chemical school "Dr. Djordje Radic"-Kraljevo during two growing seasons. By examining the physical properties of grain, Nonijus was achieved the highest average yield in both growing seasons (4.140 t ha-1, 5.706 t ha-1).
The significant difference in the significance between the impact of the year on grain quality in the examined barley varieties was significant for grain yield. The established differences in significance from the point of view of the genotype to the average values of grain yield were statistically not significant. U radu su prikazani rezultati ispitivanja ozimih sorti ječma (Rekord, Grand, NS 565 i Nonijus). Sorte su gajene na oglednom polju Poljoprivredno-hemijske škole „Dr Đorđe Radić“-Kraljevo, tokom dve vegetacione sezone. Ispitivanjem fizičkih osobina zrna, sorta Nonijus je ostvarila najveći prosečan prinos zrna u obe vegetacijske sezone (4,140 t ha-1; 5,706 t ha-1).
Utvrđena razlika značajnosti između uticaja godine na kvalitet zrna kod ispitivanih sorti ječma, bila je značajna za prinos zrna. Ustanovljene razlike značajnosti sa stanovišta uticaja genotipa na prosečne vrednosti prinosa zrna statistički nisu bile signifikantne.
