COMPARISON OF ADVANCED OAT BREEDING LINES IN LITHUANIA

Advanced oat breeding lines were investigated in 2009–2011 at the institute of agriculture of lithuanian research centre for agriculture and forestry. the highest grain yield (4.10 t ha-1) and fat content (4.41%) was in 2009 and the highest protein and starch content (12.54% and 51.4%) was in 2011. every year the yield of oat line lia 1526-9 was higher or similar to the standard variety yield. the breeding line lia 1526-9 also gave good results for fat, protein and starch yield. every year fat, protein and starch content of naked line 1579-1 was higher in comparison with standard variety mina ds: respectively, 7.39%, 12.6%, and 61.7% (standard variety 6.49%, 12.3%, and 55.7%) in 2009, 6.27%, 15.1%, and 60.7% (standard variety 5.06%, 11.5%, and 52.8%) in 2010 and 6.24%, 15.1%, and 63.6% (standard variety 5.66%, 14.0%, and 58.4%) in 2011. significantly higher yields of fat, protein and starch per hectare were obtained in 2009 and reached 176, 454, and 1910 kg ha-1. fat, protein and starch yields per ha of naked oat breeding lines were not higher than those of hulled oat breeding lines because of their low grain yield.
