New NS varieties of six-rowed winter barley

Abstract

The paper describes the characteristics of several new NS varieties of winter six-rowed barley released in Serbia between 2004 and 2007. These are Somborac, Ozren, Javor, Novosadski 773, Sremac and Leotar. In the official variety trials in the country, all six of these varieties outyielded the check variety, and the margins were as follows: Somborac - 3.4%, Ozren - 5.0%, Javor - 7.3%, Novosadski 773 - 3.4%, Sremac - 7.4%, and Leotar - 7.2%. Yield levels in absolute terms depended on the variety as well as year. All six-rowed NS varieties headed earlier than the check and had better resistance to lodging than the check has. The test weight of the new varieties was 70.2-73.8 kg/hl and the 1000-grain weight 33.4-50.2 g. The cellulose content was 4.4-4.8%, the fat content 1.4%, and the protein content 13.3-14.6%. The high variability of the new NS varieties of winter six-rowed barley makes it possible to choose the most suitable genotype for each barley-growing area in the country. .

U radu su prikazane osobine novih NS sorti ozimog višeredog ječma - Somborac, Ozren, Javor, Novosadski 773, Sremac i Leotar, koje su registrovane u Srbiji u periodu 2004-2007. godina. U ogledima Komisije za priznavanje sorti Republike Srbije sve sorte imale su veći prinos od standarda; sorta Somborac za 3,4%, sorta Ozren za 5,0%, sorta Javor za 7,3%, sorta Novosadski 773 za 3,4%, sorta Sremac za 7,4% i sorta Leotar za 7,2%. Apsolutne vrednosti prinosa zavisile su pored sorte i od perioda ispitivanja. Sve nove sorte klasale su ranije od standarda i imale bolju otpornost na poleganje. Hektolitarska masa novih sorti iznosila je 70,2-73,8 kg/hl, a masa hiljadu zrna 33,4-50,2 g. Sadržaj celuloze iznosio je 4,4-4,8%, masti 1,4%, a proteina 13,3-14,6%. Varijabilnost novih NS sorti ozimog višeredog ječma osnova je za izbor odgovarajuće sorte za svako proizvodno područje u Srbiji. .
