Breeding for improvement of technological and nutritional properties of the wheat grain in Western Siberia Abstract uri icon

abstract

  • Western Siberia is one of the leading regions of Russia for high-quality wheat grain production. The modern approach to assessing the wheat quality includes two interrelated indicators: nutritional value and technological properties. Breeders have paid a lot of attention to technological properties. They achieved significant progress in this field in most of the world, including Russia. The second indicator is the nutritional properties of wheat products that positively affect human health. They are studied far less, and only in the last 5-10 years, scientists began to pay more attention to the nutritional properties. Increasing the functional properties and nutritional value of wheat products will contribute to solving an urgent problem-strengthening human health and increasing the immune status, which is very important especially during the challenge of threats like the coronavirus pandemic.

    More than 20 varieties of spring bread wheat were created in Omsk State Agrarian University with a potential yield of 4.5-7.0 t/ha and high technological and baking properties. These varieties are annually sown in the Ural and Western Siberian regions of Russia on the area of ​​more than half a million hectares. The unique collection of wheat for breeding and genomic technologies was created in Omsk SAU to improve the nutritional and technological properties. The collection consists of more than 400 accessions of bread wheat, including hexaploid synthetics; coloured wheat with purple, blue, brown, and black grain; landraces; wild relatives (T. dicoccum T. spelta, etc.). The collection was genotyped with usage of KASP-markers and GWAS for economically valuable traits, including grain quality traits. A high-yielding variety EF 22 with purple grain, high technological properties, increased content of phenolic compounds and zinc, was transferred to the State Variety Trial. Also, this variety has complex resistance to diseases and drought tolerance. The perennial wheat breeding is carried out. The State Register of Breeding Achievements included the first Russian large-grain wheatgrass (Th. intermedium) variety Sova, recommended for cultivation in all regions of Russia in 2020.
