Grain Quality of the Naked Mutant Oats Lines from Variety Mina
Keywords:
Avena; experimental mutagenesis; grain quality; naked oatAbstract
Seeds of spring oats variety Mina (Bulgaria) were treated with gamma rays So60 in 4 doses of 50, 100, 150 and 200 Gy and 4 concentrations of sodium azide – 0.1 mM, 0.3 mM, 1 mM and 10 Mm. Used mutagenic factors have a positive effect on the content of lysine and lysine in the grain and protein on lowering the percentage of hull seeds. There is established a positive effect on specific and total mass of grain. After irradiation with gamma rays at doses of 100, 150 and 200 Gy and with sodium azide at a concentration of 0.1 mM were obtained mutant lines M 10/46, M 15/14/2, M 15/21, M 15/25, M 20/26 and Mx 10/43, that exceeds the standard in content of crude protein (22.4) and lysine (0.75 – 1.12%). Line M 10/46 also features a low hull and black seeds.
