The development of fruit crops breeding modern trends in the Nikitsky Botanical Gardens

Abstract

The research results on the fruit cultures breeding in the Nikitsky Botanical Gardens are given along the lines of partial plant genetics; identification of the consistent patterns in inheritance of some traits of cultural plants; definition of a genetic potential and allocation of the useful properties’ sources; creation of valuable traits’ donors on the mono- and polygenic basis; using the methods of a remote and intraspecific hybridization, the creation of new adaptive, high-yielding cultivars with the fruits of a high quality meeting the current requirements of intensive gardening; increase of yield, resistance to the negative environmental conditions and biogenic damaging factors, primarily fungal, bacterial and viral infections; a yield forecasting on the basis of the developed ontogenetic model, which determines the dependence of productivity on the selected characteristics of cultivars and the environmental factors in the process of a regression analysis.
