Evaluation of the adaptive potential of the pear gene pool collection in the Nikitsky Botanical Gardens

Abstract

The results of many years of research in evaluation of the adaptive potential of the gene pool collection of pears growing in the Nikitsky Botanical Gardens are represented in this article. The cultivars included in various groups of cultivar types with late flowering, flower resistance to spring frosts, drought tolerance, resistance to major diseases and productivity have been identified. The highest indicators of adaptability, productivity and quality of fruits are distinguished by the cultivars of the Crimean selection - the Nikitsky Botanical Gardens and the Crimean Experimental Station of Gardening. Among them, the following cultivars deserve the greatest attention for widespread introduction into industrial intensive horticulture of the Crimea and other southern zones of fruit growing: Mariya, Mriya, Tavricheskaya, Yakimovskaya, Desertnaya, Izyuminka Kryma, Izumrudnaya, Nadezhda Stepi, Novosadovskaya, Rada, Diva. For use in breeding programs, as sources of valuable traits, the listed domestic and foreign cultivars can be used - Bere Klerzho, Zharzhonel', Triumf Zhoduan', Dekanka Bushe, Viktoriya, Vystavochnaya, Noyabr'skaya Moldavii, Bukovinka, Zhanna d ,Ark, Mervey Ribe and others.
