Based on the Bestosta 1 soft winter wheat variety, mutants were identified by gliadin loci: two mutations in the Gli-B1b allele and one in the Gli-R1 locus in the wheat-rye translocation 1BL.1RS. The Gli-R1 mutant with enhanced synthesis of one -secaline component, the mutant with altered lower -secaline mobility had lower hardness compared to the corresponding lines without mutations. The lack of synthesis of -gliadin and lower minor -gliadin (line D4-0g) also led to a decrease in the hardness of the mutant in the Gli-B1b allele and to an increase in SDS sedimentation rate. The mutant D4-0g line with no gamma-gliadin and minor omega-gliadin did not differ from the D4 line in terms of ear productivity. Line D4-0w with no expression of major omega-gliadin had significantly lower values of grain weight from ear and spikelet and the number of grains from ear and spikelet than line D4. Mutants B3-2sw with enhanced omega-secaline synthesis and B3D4-3r with altered omega-secaline motility had higher values of ear productivity compared to the corresponding lines without mutations.
