This paper studied the variability of tree height, grain yield and protein content in different varieties of spring barley. Analyzed characteristics are varied when the investigated barley varieties. Average values of tree height varied from 75.6 cm (itinerary) to 83.0 cm by a cultivar of barley novosadski 488. The highest average yield was achieved double-row spring barley Viktor (5482 kg ha-1) and the lowest average grain yield achieved double-row spring barley novosadski 488 (4890 kg ha-1). The average height of the trees was 79.4 cm. Average grain yield was 5130 kg ha-1. Average protein content in all tested varieties amounted to 13%.U ovom radu je izučavana varijabilnost visine stabla, prinosa zrna i sadržaja proteina kod različitih sorti jarog ječma. Analizirane osobine su varirale kod izučavanih sorti ječma. Prosečne vrednosti visine stabla su varirale od 75,6 cm (jadran) do 83,0 cm koju je ispoljila sorta ječma novosadski 488. Najveći prosečan prinos zrna je ostvario dvoredi jari ječam viktor (5482 kg ha-1) a najmanji prosečni prinos zrna je ostvario dvoredi jari ječam novosadski 488 (4890 kg ha-1). Prosečna visina stabla je iznosila 79,4 cm. Prosečan prinos zrna je iznosio 5130 kg ha-1. Prosečan sadržaj proteina u zrnu kod svih ispitivanih sorti je iznosio 13%
