Occurrence of cytogenetic effects under the action of epimutagen in winter wheat

Research on studying the features of 0.01%, 0.05%, 0.10% and 0.50% epimutagen Triton-X-305 impact at cellular level, which means way identifying viability pollen in plants first generation, cytological analysis chromosomal aberrations cells primary meristem germinal roots during germination bread winter wheat seeds have been conducted. this direction allows us to significantly improve monitoring same type substances environment forecast nature their action DNA-level. Genotypes Podolyanka Spivanka created by Ukrainian selection varieties French Altigo, Courtot, Lyrik, Flamenko studied. These genotypes were selected order characterize possible genotype-mutagenic interactions for a compound complex hereditary pattern range concentrations with maximum contrast taking into account high site-specific effect. The main purpose research was identify specificity agent Triton X-305 level parameters fully showing effect substance subsequent induction biodiversity enhancement variability level. Such indicators as sterility effected various concentrations, total frequency rearrangements, spectrum including fragments double fragments, single bridges, micronuclei lagging chromosomes investigated. ratio bridges an indicator active factor nature, number two or more rearrangements genetic toxicity has established. As result, weaker overall rearrangement shown unlike other factors mutagenic time changing obtained favour chromosomes. In addition, are determined meaningful specific impact, differences less contrasting. There is also decreasing fertility, however, parameter highly dependent source material. future, we intend assess variability, primarily visual material generations, well through biochemical analysis, yield qualities morphometry
