Abstract

AbstractHybridization ofBrassica napuswith various Brassicaceae species can result in obtaining new forms with increased resistance to blackleg, a dangerous disease caused mainly byLeptosphaeria maculans. In this study, we aimed to correlate the field resistance of selectedBrassicahybrids to blackleg with chromosomal structure revealed by Fluorescencein situhybridization. Tested genotypes varied in the number of chromosomes and rDNA signals. The greatest variation was observed for A1-type chromosomes. Field evaluation also revealed significant differences inL. maculansresistance. Performed analyses allowed to distinguish threeB. napus×Brassica fruticulosagenotypes in which variable patterns of chromosomal structure might be connected to field resistance. However, a more thorough study, including the detection of all A-genome chromosomes, is required.
