The content of protein (crude and true), starch, fat, ash and husk in oats grain from experimental fields in Beskid Niski were tested in the years 1995-1997. The experiments were carried out on strains: STH 21024/93, STH 197/91, STH 2009/91, STH 2594 in comparison with cultivar German and Dukat. Dukat had more starch only than German but had also higher yield of seeds effected in higher yield of protein, fat and starch on 1 ha. The new strain STH 197/91 had higher content and yield of protein but had also high content of husk. Strain STH 2594 had the lowest content of husk and the lowest level of protein.
