Technology of accelerated breeding of new garden plum varieties (Prunus domestica L.)

Abstract

The article presents the results of the technology of accelerated breeding of new garden plum varieties by grafting on dwarf rootstock BBA 1, which reduce the time of breeding and primary evaluation of varieties to 10 years. For stone crops, the staff of the Krymsk EBS, VIR Branch branch offers a technology that allows to improve the methods of evaluating hybrid seedlings in the process of their growing in a breeding garden using intensification elements. The paper also shows the results of the source material evaluation – isolated hybrid forms of garden plum obtained at the station from directed crosses using parental forms combining in their genotype a number of positive traits: early maturity, large-fruitness, high yield and fruit quality. The technology of accelerated cultivation and evaluation of hybrid seedlings can be used in the breeding of various stone fruit crops.
