Polimorphism of marker loci, linked with QTL controlled seed traits

  • O. A. Zadorozhna


Aims. Marker assisted selection of sunflower (Helianthus annuus L.) lines with different seed oil content and some fatty acids. Methods. SSR-analysis, oil content, fatty acids analysis of sunflower lines. Results. There is a polymorphism in marker loci, which tightly linked with QTL controlled oil content and other seed traits. Conclusions. The polymorphism of loci ORS371 and ORS1068 is not enable for marker assisted selection of seed oil content. There is a high oleic acid content line with special marker allele.

Key words: Helianthus annuus, marker assisted selection, seed oil content, fatty acids.
