Dr. Dragoljub Maksimovic and Miodrag Krsti, dipl. ing., are the breeders of the new winter oat cultivar "Vranac". Results based on three years of microtrials indicated that the new winter oat cultivar had an average grain yield of 5087 kg/ha. The standard cultivar "Mustang" had 4373 kg/ha, which was significantly higher yield for LSD0,05 and LSD0,01.
Cultivar "Vranac" has higher level of freezing tolerance on temperature - 12°C. It has significantly shorter stem height, higher content of crude proteins and lipids in BEM then the standard cultivar "Mustang" (Table 1). Genetic potential for grain yield of the new winter oat cultivar Vranac is over 7000
kg/ha. Resistance to Erysiphe graminis
avenae in 1996 (Kragujevac) was complete.
