U ovom radu su ispitivane osobine kvaliteta zrna pet genotipova ozimog krupnika (Nirvana, KG-37-8/3, KG-54-7/3, KG-54-8/1 i KG-54- 2/3). Ogledi su izvedeni po principima organske proizvodnje tokom dve vegetacione sezone. Urađene su analize sadržaja proteina u zrnu i hektolitarska masa zrna. Sadržaj proteina, u proseku, se kretao u rasponu od 12,03% (KG-54-8/1) do 13,06% i 13,02% (KG-54-2/3 i KG-54-8/1). Vrednosti su bile statistički značajno veće (13,59%**) u prvoj nego u drugoj godini istraživanja (11,90%**). U ovim istraživanjima, u proseku za obe godine, najveću hektolitarsku masu imala je linija KG-37-8/3 (82,46 kg hl-1), koja je imala i najveću vrednost u celom ogledu (88,30 kg hl-1), a zatim linije KG-54-7/3 (79,16 kg hl-1) i KG-54-2/3 (78,80 kg hl-1). Analizom varijanse su ustanovljene statistički visoko značajne razlike između genotipova, godina i njihovih interakcija za obe ispitivane osobine kvaliteta zrna krupnika. In this work, the grain quality characteristics of five genotypes of winter wheat (Nirvana, KG37-8/3, KG-54-7/3, KG-54-8/1 and KG-54- 2/3) were examined. The experiments were carried out according to the principles of organic production during two growing seasons. Analyzes of grain protein content and hectoliter grain weight were performed. The protein content, on average, ranged from 12,03% (KG-54-8/1) to 13.06% and 13.02% (KG-54-2/3 and KG-54-8/1, respectively). The values were statistically significant higher (13.59%**) in the first than in the second year of the research (11.90%**). In these studies, on average for both years, line KG-37-8/3 (82.46 kg hl-1) had the highest hectoliter weight, which also had the highest value in the entire trial (88.30 kg hl-1 ), and then lines KG-54-7/3 (79.16 kg hl-1) and KG-54-2/3 (78.80 kg hl-1). Analysis of variance revealed statistically highly significant differences between genotypes, years and their interactions for both tested grain quality traits. |
