New spring malting barley varieties: NS Mile and NS Marko

Abstract

Breeding program at the Institute of Field and Vegetable Crops is directed to the development of new barley cultivars with a high and stable yield, good malting quality and high resistance abiotic and biotic stress. As a result of this work, two new varieties of spring malting barley NS Mile and NS Marko were developed in the 2012. The two-year trial of Commission for the registration of varieties, Republic of Serbia, showed that the NS Marko and NS Mile are distinct, uniform and stable varieties, and that on average they had significantly higher yield and better quality than standard variety for all the test sites and all years. NS Marko and NS Mile are new early varieties of NS malting barley that are characterized by high genetic potential for yield, which is more than 9 t ha-1, as well as by high quality, especially high content of malt extract and lower protein content compared to standard cultivar.

Oplemenjivački rad na ječmu u Institutu za ratarstvo i povrtarstvo je usmeren ka stvaranju novih sorti ječma koje će imati visok i stabilan prinos, dobar pivski kvalitet i visoku tolerantnost prema abotičkim i biotičkim faktorima. Kao rezultat ovog rada, tokom 2012. godine su priznate dve nove sorte jarog pivskog ječma NS Mile i NS Marko. U dvogodišnjim ogledima Komisije za priznavanje sorti Republike Srbije je utvrđeno da su NS Mile i NS Marko različite, uniformne i stabilne sorte i da su u proseku za sve lokalitete i godine ispitivanja ostvarile prinos vrlo značajno veći od prinosa sorte standarda i bolje parametre kvaliteta. NS Mile i NS Marko su najnovije rane sorte novosadskog jarog pivskog ječma koje se odlikuju visokim genetskim potencijalom za prinos, koji iznosi preko 9 t ha-1 i visokim kvalitetom, pre svega manjim sadržajem proteina i većim sadržajem ekstrakta u odnosu na sortu standard.
