NÁVRH CORE KOLEKCE SLIVONÍ S OHLEDEM NA POMOLOGICKÉ TŘÍDY A ODOLNOST K VIROVÉ ŠARCE ŠVESTEK PPV [THE DESIGN OF THE PLUM CORE COLLECTION WITH REGARD TO POMOLOGICAL GROUP AND RESISTANCE TO PPV PLUM POX VIRUS]

Abstract

Within the plum gene pool collection, where more than 150 genotypes of individual pomological groups were planted, a core collection was created taking into account the behaviour of the genotypes to the plum virus and their pomological groups. The infection was carry out on the base of field tolerance, without artificial infection in conditions of medium pressure of plum pox virus. Pomological groups were simplified and modified according to Hegi classification and the core collection was compiled based on the diversity of pomological groups and resistance to plum pox. Perspective genotypes were selected in each pomological group from the point of view of growing practice, breeding and processing.
