Molecular marking in breeding Brassica oleracea L. for resistance to Xanthomonas campestris pv. campestris

Abstract

In the presented study, we have studied polymorphism of 30 microsatellite loci in terms of resistance to black rot (Xanthomonas campestris). Three SSR markers (Ol10-C01, Ol11-H06, BoESSR 726) were identified, showing polymorphism in white cabbage forms with contrasting resistance to black rot. Also, part of the F2 breeding material was analyzed using markers Ol10-C01, Ol11-H06. It was found that they reveal all types of allelic state of genes in a segregating population in accordance with the Mendelian rule of segregation, which makes these markers suitable for further use in studies on the basis of cabbage resistance to black rot.
