NS Ibar and NS Ulog: New winter feed barley varieties

Abstract

At Institute of Field and Vegetable crops for decades, new varieties of winter six-row feed barley having high yield, good adaptability, stability and quality are produced. As a result of long process of breeding, two new varieties of winter six-row barley - NS Ibar and NS Ulog have been selected. The primary aim during creation of these varieties was selection for yield, and maintaining quality and other agronomic traits at least to the standard variety level. The two-year multilocation trial of Commission for the registration of varieties, showed that the NS Ibar and NS Ulog are distinct, uniform and stable varieties, and that on the base of average for all the test sites and years they achieved a significantly higher yield than the standard variety. New varieties of winter six-row feed barley are characterized by high genetic potential for yield, which is more than 10 t ha-1. NS Ibar i NS Ulog had a shorter plant, while the resistance to lodging was at the level of the standard variety.

U Institutu za ratarstvo i povrtarstvo se decenijama stvaraju nove sorte ozimog višeredog stočnog ječma, koje imaju visok prinos, dobru adaptabilnost, stabilnost i kvalitet. Kao rezultat višegodišnjeg procesa oplemenjivanja, stvorene su dve nove sorte ozimog višeredog stočnog ječma - NS Ibar i NS Ulog. Primarni cilj prilikom stvaranje ovih sorti je bila selekcija na prinos, uz zadržavanje kvaliteta i drugih agronomskih osobina najmanje na nivou sorte standarda. U dvogodišnjim multilokacijskim ogledima Komisije za priznavanje sorti utvrđeno je da su NS Ibar i NS Ulog različite, uniformne i stabilne sorte i da su u proseku za sve lokalitete i godine ispitivanja ostvarile prinos značajno veći od prinosa sorte standarda Grand. Nove sorte ozimog višeredog stočnog ječma odlikuju se visokim genetičkim potencijalom za prinos koji iznosi preko 10 t ha-1. NS Ibar i NS Ulog su imale kraću stabljiku, dok je otpornost prema poleganju bila na nivou sorte standard.
