dc.description.abstract | Sunflower downy mildew has a great economic importance in countries where sunflower is grown. Primary infected plants significantly decrease seed yields while secondary infection has no significant influence. Major objective of this study was to developed sunflower genotypes genetically resistant to dominant races of downy mildew in Serbia. During this work two co-dominant CAPS markers for Pl-6 gene were developed which can also be used for Pl-7 gene. For introduction of these genes in breeding program marker assisted selection (MAS) was used. Developed commercial sunflower inbred lines exhibit resistance to all known races of downy mildew in our country indicated incorporation of resistance to downy mildew in well-known and widely produced hybrids VELJA, KAZANOVA and RIMI-PR. Pl-genes were introduced to large number of new inbred lines and new downy mildew resistant hybrids PLAMEN, SREMAC, DUŠKO and OLIVA were released. These new hybrids reach higher seed and oil yields then hybrids widely produced. | en |
dc.description.abstract | Plamenjača suncokreta ima veliki ekonomski značaj u svim zemljama u kojima se gaji suncokret. Svaka obolela biljka od primarne zaraze ima značajno smanjenje prinosa, dok sekundarna zaraza nema bitniji značaj. Stoga je i postavljeni cilj ovog rada bio stvaranje genotipova suncokreta koji su genetski otporni na dominantne rase plamenjače kod nas. U toku ovog rada razvijena su i dva kodominantna CAPS markera za Pl-6 gen za koja je utvrđeno da se mogu koristiti i za Pl-7 gen tako da je za unošenje ovih gena korišćena i marker asistirana selekcija (MAS). Stvorene su kod komercijalnih linija suncokreta forme otporne na sve rase plamenjače prisutne kod nas, što je omogućilo prevođenje već poznatih i u širokoj proizvodnji raširenih hibrida VELJA, KAZANOVA i RIMI-PR u verzije otporne na plamenjaču. Ugrađeni su pl-geni u veći broj novih inbred linija i stvoreni su novi hibridi otporni na plamenjaču, a to su: PLAMEN, SREMAC, DUŠKO i OLIVA. Novostvoreni hibridi ostvaruju viši prinos semena i ulja u odnosu na hibride koji su nalaze u širokoj proizvodnji. | sr |
