Variability of class properties of different cultivars and lines of two-row barley

Istraživanja su sprovedena tokom dve godine na oglednom polju Instituta za kukuruz u Zemun Polju. Cilj ovog istraživanja je bio utvrđivanje značajnosti izvora varijacije dužine klasa, mase zrna i broja zrna po klasu kod dvoredog ječma, kao i sorti i linija na bazi ispitivanih osobina i izdvajanje superiornih genotipova. Prosečna dužina klasa za sve ispitivane genotipove dvoredog ječma varirala je od 8,07 cm (2010) do 8,87 cm (2009), dok je prosečna dvogodišnja dužina klasa iznosila 8,47 cm. Prosečan broj zrna po klasu je iznosio 24,1, dok je prosečna masa zrna po klasu za sve ispitivane genotipove iznosila je 1,132 g.The research was conducted for two years in the experimental field of the Maize Research Institute in Zemun Polje. The aim of this study was to determine the significance of the source of the class components of the two-rowed barley, as well as the varieties and lines based on the investigated properties and the extraction of superior genotypes that exhibit high and stable yields of class. The average length of spike for all examined genotypes of two-rowed barley ranged from 8.07 cm (2010) to 8.87 cm (2009), while the average length of spike was 8.47 cm. The average number of grains per spike was 24.1, while the average grain weight per spike for all investigated genotypes was 1.132 g
