Modern sunflower breeding is significantly diversified due to the different needs of agricultural production. The breeding of sunflower varieties and hybrids is carried out at V.S. Pustovoit All-Russian Research Institute of Oil Crops (VNIIMK) in all areas in demand on the market and is based on fundamental biological research. In the field of breeding for faster maturing, the following commercial cultivars were obtained: very early maturing, cv. Skormas and the three-way hybrid Achilles, early maturing cvs. Varyag and Uspekh, medium maturing cvs. Amelie, Aris and Aurus. Within the framework of breeding for immunity, eight hybrids and one variety have been produced. So at the Don experimental station (Rostov region), productive hybrids were bred, resistant to the virulent broomrape of the G race due to the presence of the Or7 gene: ‘Gorstar’, ‘Gorfild’, ‘Grant’, ‘Status’, ‘Fogor’ and the three-way hybrid Nika. On the central experimental base, the following were obtained: the mid-early hybrid Typhoon and the earlymaturing variety Platonych with resistance to common races of downy mildew and a high oil content of achenes (up to 53 %) as well as the mid-early hybrid Tayzar, which is simultaneously resistant to virulent races of broomrape and to the causative agent of downy mildew. The early maturing large-fruited sunflower variety Belochka was included in the“Russian State Register of Selection Achievements…”, and the large-fruited varieties Karavan, Konditer and Kalibr are currently undergoing state tests. The breeding use of germplasm with genes for herbicide resistance wasaccompanied by their extensive genetic study. A practical recommendation for all three alleles of the ALS gene (Imr, CLHA-Plus, Sur) was the need to create homozygous hybrids for their reliable use in appropriate production systems. For Clearfield technology, the hybrids Imidzh, Arimi and Immi have been developed; for Clearfield Plus, the hybrid Klip; and for Express Sun (or SUMO), the hybrid Surus. Klip and Surus are mid-oleic. All newly developed fertile ornamental sunflower varieties – Aurelia, Fizalia, Zhemchuzhny, Rumyanets, Agat and Mazhor – were transferred for practical use to a sterile CMS RIG basis. Thus, new achievements have been attained across the entire spectrum of modern trends in sunflower breeding.

Sunflower broomrape (Orobanche cumana Wallr.) is an obligate parasitic plant that specifically infects sunflower and can cause significant yield losses. In this regard, obtaining sunflower varieties resistant to broomrape is an important task for agriculture. Sunflower breeding for resistance to broomrape was initiated in the beginning of the 20th century in USSR. However, the production of new resistant sunflower varieties was accompanied by the emergence of new virulent broomrape races that overcame the effect of resistance genes. For a number of sunflower genetic loci that determine resistance to broomrape, the location on the genetic map was determined, but only for some of them probable candidate genes were identified and the possible molecular mechanism of their action was described. In addition, transcriptomic data have recently been obtained for broomrape-resistant and susceptible sunflower varieties, which also makes it possible to get closer to understanding the molecular basis of resistance formation. This review focuses on molecular genetic mechanisms of sunflower resistance to broomrape, identified on the basis of genetic mapping of resistance loci, determination of probable candidate genes, as well as available transcriptomic data.
