The objects of the work: i) recording the elements of productivity; ii) establishing the weight (%) of the year, genotype, year x genotype interaction factors of in the source of variability character; iii) calculation of genetic parameters of variability and heritability, heritability coefficient; iv) determination of the biochemical quality of wheat grains. Research methods: biometric, biochemical, mathematical, statistical. Results obtained - the particularities were established: i) variability, heritability, the factorial weight of the conditions of the year and the wheat genotype in the source of variation of the productivity elements of the spike; ii) heritability and genetic advance; iii) the content of proteins, wet gluten, dry gluten, carbohydrates in grains during the years of study.roheritabilityproductivityqualityvariabilitywheatArticlehttps://doi.org/10.59295/spd2024n.16
