Methodology of Breeding Ecologically Resistant Varieties of Oats
- 13 Downloads
To breed ecologically resistant varieties, it is necessary to determine breeding methods and their sequence and combinations, i.e., to develop a methodology. In 2003, hybrid material of covered oats was obtained on 76 cross combinations. In 2008–2009, 345 of the best elite plants were selected, and further selection was made under different ecologic conditions: sufficient or excess humidification and drought on neutral and aluminum-acid sod-podzolic soils (Kirov region), short growing season on sod-podzolic soils (Udmurt Republic), on dark-grey heavy loam forest soils (Chuvash Republic), and drought on middle-loam chernozem (Samara region). Screening on disease resistance and improving selection under field and laboratory conditions was performed. As a result, the new, adaptive variety Berber was passed into State Varietal Test in 2016. The variety combines high productivity (7.8 t/ha) and valuable grain quality: test weight 608 g/L, huskiness 26.3%, raw protein content 13.87%, raw fat content 3.18%, and resistance to loose smut and crown rust.
