Varieties of Japanese plum (Prunus salicina Lindl.) as donors of large-fruitness in the breeding of Russian plum (Prunus rossica Erem.)

Abstract

In the North Caucasus region, at the Krymsk Experiment Breeding Station, VIR Branch, as a result of breeding varieties of Russian plum (P. rossica Erem.) with varieties of Japanese plums (Angeleno, Larry Ann, Black Amber, Constanza), large-fruited elite hybrids with commodity-consumer qualities of fruits were obtained. A genealogical analysis of the varieties used in breeding with large-fruiting trait as donors of this trait was carried out.
