MOLECULAR MARKING IN A WHITE CABBAGE SELECTION FOR RESISTANCE TO ALTERNARIA BLIGHT

Abstract

In the presented study, the polymorphism of SSR loci was studied on the basis of the resistance of white cabbage to alternariosis. This work was carried out in order to identify effective and informative ISSR markers for the identification of donor alleles of resistance to alternariosis in the genotypes of hybrid plants of culture. Of the 20 tested markers, only 3 (PBCESSRJU13, PBCESSRJU6, NI-F02a) demonstrate an allelic difference between the isogenic lines of white cabbage contrasting in resistance to Alternaria blight. They will become the basis for subsequent studies on the analysis of cleavage in segregating populations and the determination of informative DNA marker systems co-inherited with the sign of resistance of cabbage to alternariosis.
