Abstract

We evaluated the quantitative and qualitative characteristics of somaclones of the first generation (SC1) obtained in vitro from 11 spring wheat varieties in the culture of immature embryos. Phenotypic deviations from the parental forms were found in 28.7% of the regenerated plants. The frequency of variability ranged from 20 to 56.6%, depending on the donor of the explant. We found that the genotype, as well as the changes that occur at the cellular level during the cultivation, affect the variability of the traits.
