Evaluation of different oat varieties to identify prospective breeding lines for organic agriculture

Implications Prospective oat breeding lines investigated in this study under organic management conditions showed significant variation according to grain quality traits that are important for grain processors such as grain size, test weight (TW), grain grades, groat percentage, groat yield and damaged groats. It shows the possibility to develop improved oat varieties specifically designed for organic agriculture that possesses oat grain processing requirements to obtain qualitative organic oat products

Variation in β-Glucan, Protein and Fat Concentration of Oats Created in Latvia

Consumption of dietary fibre has potential in improving nutrition and health. For further breeding of oats, it is necessary to increase knowledge on variation in the content of fibre and bioactive components in oats. Therefore, the aim of the present investigation was to study the extent of variation in β-glucan concentration of oats grown in Latvia and to evaluate association of β-glucan concentration with protein and fat concentration in newly created oat breeding lines. In 2015 and 2016, concentration of protein, fat, and β-glucan in grain of hulled oat varieties ‘Laima’, ‘Peppi’, and ten breeding lines was determined. The obtained results showed a wide range of fat concentration among varieties, with a range from 5.9 to 8.3%. The concentration of β-glucan ranged from 1.8 to 3.6% depending on the year. The β-glucan concentration had medium close positive correlation with lipid and weak significant positive correlation with protein concentration, which significantly differed among genotypes
