“…All lines were developed at the VNIIMK institute. Elite lines VK101 and VK303 are used to produce a simple interlinear middle-early sunflower hybrid “Typhoon” registered at VNIIMK ( Trembak et al 2018 ). Lines VK876 and VK195 are used to produce “Oxy” hybrid which oil demonstrate high content of oleic acid and γ- and δ-tocopherol forms that increase oxidative stability ( Demurin et al 2016 ).…”

Tocopherols are antioxidants that preserve oil lipids against oxidation and serve as a natural source of vitamin E in the human diet. Compared with other major oilseeds like rapeseed and soybean, sunflower (Helianthus annuus L.) exhibits low phenotypic diversity of tocopherol composition, both in wild and cultivated accessions from germplasm collections. Two major mutations that alter tocopherol composition were identified in genetic collections, and several studies suggested additional loci controlling tocopherol composition, with their expression possibly depending on the genetic background. In the present study, we performed QTL mapping of tocopherol composition in two independent F2 crosses between lines with contrasting tocopherol composition from the Pustovoit All-Russia Research Institute of Oil Crops (VNIIMK) collection. We used genotyping-by-sequencing (GBS) to construct single nucleotide polymorphism (SNP) based genetic maps, and performed QTL mapping using quantitative and qualitative encoding for phenotypic traits. Our results support the notion that the tocopherol composition in the assessed crosses is controlled by two loci. We additionally selected and validated two SNP markers for each cross which could be used for marker assisted selection.

Oleic acid is a monounsaturated fatty acid increasing oil oxidative stability. High content of oleic acid is thus a valuable trait in oilseed crops. Sunflower (Helianthus annuus L.) normally accumulates linoleic acid as a major fatty acid, but a mutant expressing a high oleic phenotype form was previously obtained by chemical mutagenesis and mapped on the sunflower genome. Several studies suggest the presence of additional genes involved in the control of the high content of oleic acid, with their expression possibly depending on the genetic background. To test this hypothesis, we performed a QTL mapping of the high oleic acid trait within two independent F2 crosses involving lines with contrasting oleic acid content from the Pustovoit All-Russia Research Institute of Oil Crops (VNIIMK) collection. We applied genotyping-by-sequencing (GBS) to construct single nucleotide polymorphism-based genetic maps and performed QTL mapping using quantitative and qualitative encoding for oleic acid content. Our results support the finding that the oleic acid content in the assessed crosses is controlled by one major effect locus. However, different dominant/recessive effects of the major locus were reported for both crosses. Additionally, a possible translocation between chromosome 7 and 14 was reported in one assessed cross. We defined a set of single nucleotide polymorphism markers for each cross which could be used for marker-assisted selection.

“…The VNIIMK VK195 and VK876 parental lines of the "Oxy" hybrid demonstrating increased oil resistance to thermal oxidation and expressing high oleic phenotype (Demurin et al 2016) were used as hand emasculated female lines. They were crossed with the parental (used as males) lines VK101 and VK303 used to produce modern middle early hybrid "Typhoon" (Trembak et al 2018), respectively. To perform scanning for genetic markers for high OAC, we applied a genotyping by sequencing approach to obtain high-density SNP maps and next performed QTL mapping.…”
