Komponente prinosa dvoredog ječma

Abstract

Istraživanja su sprovedena tokom dve godine na oglednom poljuCentra za strna žita u Kragujevcu. Cilj ovog istraživanja je bio utvrđivanje značajnosti izvora varijacije komponenti prinosa 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 8,10 cm(2009/10) do 7,64 cm (2008/09), dok je prosečna dvogodišnja dužina klasa iznosila 7,87 cm. Broj zrna po klasu kod ispitivanih genotipova dvoredog ječma varirao je u opsegu od 20,99 (2009/10) do 23,30 (2008/09), dok je prosečan dvogodišnji brojzrna po klasu iznosio 22,15.

The research was conducted for two years in the experimental field of the Centre for Small Grains in Kragujevac. The aim of this study was to determine the significance of the source of the yield 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. The average length of spike for all examined genotypes of two-rowed barley ranged from 8.10 cm (2009/10) to 7.64 cm (2008/09), while the average length of spike was 7.87 cm. The number of grains per spike of the studied genotypes of two-rowed barley ranged from 20.99 (2009/10) to 23.30 (2008/09), while the average number of grains per spike was 22.15.
