Abstract
The naked oat strain 5T8.33, derived from wide crosses between winter oats and Avena macrostachya, was investigated in field trials, on 5 m2 plots, in four locations, in the years 2012 and 2013. In relation to the standard naked oat cultivar Siwek the strain showed better average scores for several important characters. High and stable values of thousand kernels mass (TKM = 32.7 g, 139.2% of the standard), grain protein content (18.8%, 112% of the standard), dietary fibre content (7.0%, 117.9% of the standard), resistances to lodging and to crown rust were combined with low contamination with husked grain (4.0% in relation to 16.9% in the standard). Contrary to the Siwek cultivar, the high grain quality parameters were not negatively correlated with yield. The yield potential was also high, but its stability was low. Usefulness of the strain as a source of new variation is discussed for application in oat breeding.
