Downy mildew is a fungal disease of sunflower that can lead to severe yield losses. The damage caused by the pathogen can be controlled by growing resistant sunflower varieties. Gene Pl (arg) was introgressed into cultivated sunflower from the wild species Helianthus argophyllus and provides resistance against all known downy mildew races. In this study, we used a mapping population from the cross-RHA 419/RHA-N-49. We identified a new co-segregating simple sequence repeat marker ORS675 and confirmed the co-segregation of markers ORS716 and ORS662 with Pl (arg) gene. The markers were validated on two registered resistant inbred lines RHA 443 and RHA 464, as well as on twenty inbred lines RH 1-20 obtained through methods of classical breeding. Molecular marker ORS716 was assessed for usefulness in selecting resistant progeny in 12 BC populations. Markers were found to be valuable for molecular breeding in diverse genetic backgrounds and enabled transfer of the resistance gene in differen...t sunflower genotypes.
