GENEALOGICALANALYSIS OF PERSPECTIVE PRUNUS ROSSICA CULTIVARS

The paper considered the problem of breeding new Prunus rossica cultivars, adaptive to soil and climatic conditions in the North Caucasus region, on the basis of using preliminary selection. There was carried out a genealogical analysis of Prunus rossica cultivars, which are promising for breeding programs, and donor cultivars which possess a selection-significant sign of large fruits. A number of promising and effective donor cultivars such as ‘Gigant’, ‘Kubanskaya kometa’ and ‘Obilnaya’ was recorded for inclusion into the selection process, aiming to create new plum cultivars. Having carried out preliminary studies on genealogy and the results of the inheritance of economically valuable traits from the studied cultivars, it can be concluded that the most effective and promising donor cultivars for inclusion into the breeding programs can be considered: ‘Gigant’, ‘Kubanskaya kometa’ and ‘Obilnaya’.
