Abstract

The aim of the study was to select genotypes with improved content of nutrients and of high bioactive properties from the most advanced breeding materials of oat in Poland. Material for the study comprised dehulled grain of 11 new hulled breeding lines of oats and a naked one and also two standard varieties, Arden and Bingo, together with a naked one, Nagus. The following components were analyzed: protein, minerals, lipids, digestible starch, dietary fibre and its constituents, Klason lignin, nonstarch polysaccharides with soluble and insoluble polymers including β-glucan. The viscosity of grain water extract was also determined as the main indicator of functional properties of oat and also as a simple indirect assay for measuring the level of soluble β-glucan. Husk constituted on average 25.4% of the kernel weight, its largest share (29.8%) was found in the breeding line POB 2085/09, while the smallest (21.6%) in variety Bingo. The highest content of nutrients (SSO), estimated as the sum of protein, minerals, lipids and starches was scored in two genotypes, STH 8307 and POB 2149/09 and also in variety Arden (80.2; 80.1 and 82%, respectively). With regard to the bioactive properties, the highest values were found in the grain of two naked genotypes, variety Nagus (26.7) and strain STH 8307 (24.2) and also in a dehulled grain of hulled genotype STH 8030 (23.1). The STH 8307 was a genotype combining the high nutritional value with high health-promoting properties of the grain.
