“…A set of markers have been validated − in a number of diff erent genetic backgrounds for the Or5 gene conferring resistance to race E of the parasitic weed broomrape (Orobancche cumana), infecting the sunfl ower roots (Höniges et al, 2008;Pérez-Vich et al, 2004;Tang and Knapp, 2003). Markers have been validated for the − dominant PI genes determining resistance to diff erent downy mildew races (Brahm and Friedt 2000;Hvarleva et al, 2009;Ma et al, 2017) and to the R1, Radv and Pu6 genes conferring resistance to rust (Bulos et al, 2014). QTLs controlling three resistant (stem le-− sion, leaf lesion and speed of fungal control) and two morphological (leaf length and leaf length with petiole) traits have been validated for S. sclerotiorum across generations (Micic et al, 2005) and across environments (Talukder et al, 2016).…”

Sunflower, maize and potato are among the world’s principal crops. In order to improve various traits, these crops have been genetically engineered to a great extent. Even though molecular markers for simple traits such as, fertility, herbicide tolerance or specific pathogen resistance have been successfully used in marker-assisted breeding programs for years, agronomical important complex quantitative traits like yield, biotic and abiotic stress resistance and seed quality content are challenging and require whole genome approaches. Collections of genetic resources for these crops are conserved worldwide and represent valuable resources to study complex traits. Nowadays technological advances and the availability of genome sequence have made novel approaches on the whole genome level possible. Molecular breeding, including both transgenic approach and marker-assisted breeding have facilitated the production of large amounts of markers for high density maps and allowed genome-wide association studies and genomic selection in sunflower, maize and potato. Marker-assisted selection related to hybrid performance has shown that genomic selection is a successful approach to address complex quantitative traits and to facilitate speeding up breeding programs in these crops in the future.

“…Molecular markers are crucial for understanding genome organization and provide important advantages in the means of development of new lines [ 14 ] and determination of differentiation between initial germplasm [ 15 ]. The development of molecular markers in sunflower is at an advanced level and different types of markers have been developed for marker-assisted selection (MAS) over the years.…”

The effectiveness of Pl genes is known to be resistant to downy mildew (DM) disease affected by fungus Plasmopara halstedii in sunflower. In this study phenotypic analysis was performed using inoculation tests and genotypic analysis were carried out with three DM resistance genes Plarg, Pl13 and Pl8. A total of 69 simple sequence repeat markers and 241 F2 individuals derived from a cross of RHA-419 (R) x P6LC (S), RHA-419 (R) x CL (S), RHA-419 (R) x OL (S), RHA419 (R) x 9758R (S), HA-R5 (R) x P6LC (S) and HA89 (R) x P6LC (S) parental lines were used to identify resistant hybrids in sunflower. Results of SSR analysis using markers linked with downy mildew resistance genes (Plarg, Pl8 and Pl13) and downy mildew inoculation tests were evaluated together and ORS716 (for Plarg and Pl13), HA4011 (for Pl8) markers showed positive correlation with their phenotypic results. These results suggest that these markers are associated with DM resistance and they can be used successfully in marker-assisted selection for sunflower breeding programs specific for downy mildew resistance.
