| Summary: | 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.
