dc.description.abstractThe existence of genes for a high oleic acid content (Ol-genes) has made it possible to develop high-oleic sunflower hybrids (Olivko). There are also sunflower genotypes with high levels oflinoleic, palmitic and stearic acids which makes possible the development of hybrids with different oil quality. Genes have been discovered for different tocopherol content and type based on spontaneous mutations within sunflower populations. The genes tph1 (50% alpha + 50% beta), tph2 (0-5% alpha + 95-100% gamma) and lph1tph2 (8-40% alpha 0-25% beta + 25-84% gamma + 8-10% delta) enable the development of hybrids with different tocopherol contents and types. The incorporation of the gzne Ol+tph1 into these genotypes has led to the development of high-oleic hybrids with altered tocopherol profiles. Oil of these hybrids can be sustained for much longer than standard sunflower oilcan. The process of incorporating the genes Ol+tph2 and Ol+tphjtph2 into highly productive sunflower genotypes is under way., The most important products of this line of research are the newly developed female lines the oil of which has an oleic acid content of over 90% and the male lines (restorers) with an oleic acid content in the 89-93% range. Using these lines, hybrids will be developed whose oil is going to have an oleic acid content of over 90%.en
dc.description.abstractPostojanje gena za visok sadržaj oleinske kiseline (Ol-geni), omogućilo je stvaranje visoko-oleinskih hibrida (Olivko) suncokreta. Postoje genotipovi suncokreta i sa visokim sadržajem linolne, palmitinske i stearinske kiseline a što omogućava stvaranje hibrida sa različitim kvalitetom ulja. Otkriveni su geni za različit sadržaj i vrstu tokoferola na osnovu spontanih mutacija u okviru populacija suncokreta. Gen tph1 (50% alfa + 50 % beta), gen tph2 (0-5% alfa + 95-100 % gama) i geni tph1tph2 (8-40% alfa + 0-25% beta + 25-84 % gama + 8-10 % delta) omogućavaju i stvaranje hibrida sa različitim sadržajem i vrstom tokoferola. Ugradnjom u iste genotipove gena Ol+tph1 stvoreni su visoko-oleinski hibridi sa izmenjenim tokoferolima. Kod ovih hibrida održivost ulja je značajno duža u odnosu na standardno ulje suncokreta. Proces unošenja Ol+tph2 i Ol+tph1tph2 gena u produktivne genotipove suncokreta je u toku. Najznačajniji rezultati ovih istraživanja su novostvorene linije majke sa sadržajem oleinske kiseline u ulju iznad 90% kao i linije oca (restoreri) sa sadržajem oleinske kiseline u intervalu između 89-93%. Na osnovu ovih linija biće stvoreni hibridi kod kojih će sadržaj oleinske kiseline u ulju biti iznad 90 %.sr
