The examination was done during four years period (2004/05, 2005/06, 2006/07 and 2007/08) with ten Macedonian varieties soft winter wheat: Milenka, Bistra, Lizinka, Altana, Mila, Orovcanka, Olga, Agrounija prima, Podobrena Orovcanka and Pelisterka. The average height of varieties were 89,3 cm. Regardless the year, soil, climatic conditions and breeding system, variety with the highest yield was Mila (6 570 kg/ha) which in the conventional production system gave 5 760 kg/ha, but in the organic production 7 380 kg/ha. Independent of breeding system, the best content of proteins in grain had Lizinka (15,0 %), but the lowest content of proteins was detected at Agrounija prima (12,9 %). Regardless of breeding systems, year and varieties, the general average yields on Macedonian varieties were 5 877 kg/ha. These variety of soft winter wheat used 60-70% of its genetic potential for yield production. |
