Breeding value of mutant forms of spring barley in the conditions of the Volga-Vyatka region

Many crops have a very small genetic “base”. The use of a limited number of parental forms reduces the genetic diversity of commercial varieties and exacerbates the problem of their resistance to adverse environmental factors. Induced mutagenesis is one of the means to generate genetic variation in crops in a shorter time compared to crosses and can be used to develop source material for breeding and new varieties with high yields, excellent product quality, resistance to climate change and tolerance to biotic and abiotic stresses.

At present, the yield of barley varies greatly from year to year. This is due to changes in soil and climatic conditions. In this regard, the problem of selecting new source material for the creation of varieties capable of resisting the action of abiotic and biotic stresses is acute. The study of the global gene pool of spring barley under the conditions of the Volga-Vyatka region helps to identify adaptive forms with a complex or individual traits and properties that meet modern breeding objectives.
