Cytologic research on the generally accepted methodology. Results. Through the study of diploid – tetraploid chimeras derived from experimental mutagenesis, the number of violations found in the different phases of meiosis. Characterized some diploid – tetraploid chimeras with valuable economic and biological traits.
