P-3: Marker assisted selection in Brassica napus breeding for stem canker (Leptosphaeria spp.) resistance


Abstract: Control of Leptosphaeria spp. pathogens greatly depends on the plant-pathogen
interactions and successful breeding for resistance. DNA markers have been used widely in
conventional plant breeding programmes via marker-assisted selection (MAS). Although there are numerous resistance sources in Brassica species to Leptosphaeria maculans, few molecular markers for resistance are publically available. The lack of molecular markers tightly linked to resistance genes restricts the rapid generation of resistant lines. Searching for new sources of resistance and new molecular markers is of great importance for effective screening Brassica collections. The aim of this study was to use some PCR markers and orthologous genes as markers for screening Brassica interspecific hybrids towards to increase resistance to L. maculans.
