Nazarenko M. Ecology-genetics foundations of winter wheat recurrent mutagenesis

The dissertation is dedicated to finding the ways to optimize the system of forming factor – its dose or concentration – genotype of the initial form–antropical ecosystem for predicting the effects of mutagenic activity in the early stages of programs on experimental mutagenesis, enhancement of the stability of plant systems depending on the influence of external ecogenetic factors, identification of peculiarities of fulfilment of the potential of agronomically valuable features in agroecosystems is an extremely topical issue, studied in this paper, which also considers the problem of improvement of existing methods of assessment of the source and obtained material in order to increase the efficiency of using ecogenetic variability and extending the limits of its implementation, as well as the peculiarities of the one-time and recurrent effects of form-forming factors and the dependence of the effects obtained on the adaptive response of plant systems.
