Information × Registration Number 0218U006425, 0115U007017 , R & D reports Title Specifity of mutation factors mutagen activity by winter wheat sample popup.stage_title Head Nazarenko Mykola, Registration Date 11-05-2018 Organization Dnipropetrovsk state agrarian and economik university popup.description2 The aim of our study was to develop the scientific basis for the interaction of the components of the mutant genotypic object system - mutagen - the power of the mutagenic factor and the identification of patterns of interaction when the components of the system are varied. Тhe features of mutagenic factors, its individual doses or concentrations in the induction as the general frequency of variability, and types of mutant signs, frequency of hereditary changes on the basis of certain features were revealed; the connection between the frequency and the spectrum of mutations by the method of obtaining the genotype of the mutagenic object has been proved, it has been established that the single action of the mutagenic factor leads to a decrease in its genetic activity in subsequent treatments, the features of the first generation mutagenic depression, depending on the genotype of the wheat of the soft winter, features of the manifestation of the effects of mutagenic depression, the possibility of an effect of mutagenic stimulation on individual indicators; The boundaries in which the inhibition of plant life under the influence of individual mutagens and the effects of the genotype characteristics on these limits are detected are revealed; the sensitivity of individual genotypes to mutagenic action was established and the justification for a partial preliminary forecast of such sensitivity was provided; certain features of the occurrence of mutations depending on the complex - the genotype of the object of mutagenic action - the dose or concentration of the mutagenic factor - the nature of the mutagenic factor, proved the priority and its change in the interaction of these components in the specific conditions of the mutation process; the peculiarities of genetic activity of mutagenic factors on modern varieties of Ukrainian selection of mutant, mutant-recombinant, recombinant production methods are established; the features of mutagenic factors, its individual doses or concentrations in induction as the general frequency of variability, and types of mutant signs, frequencies of hereditary changes on separate grounds were revealed.5481 Product Description popup.authors Назаренко М.М. popup.nrat_date 2020-04-02 Close
