Association Mapping for Quantitative Trait Loci Controlling Superoxide Dismutase, Flavonoids, Anthocyanins, Carotenoids, ?-Oryzanol and Antioxidant Activity in Rice

Antioxidant-rich rice is a cheaper way to solve stress-related disorders and other health benefits for the global rice-eating population. Five antioxidant traits, namely, superoxide dismutase, flavonoids, anthocyanins, ?-oryzanol 2,2?-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) activity were mapped using representative panel population through association mapping. Potential landraces carrying multiple compounds identified from The represented four genetic groups correspondence presence of antioxidants traits in each group was noticed. showed linkage disequilibrium studied based on Fst values. A total 14 significant marker–trait associations detected these traits. study validated QTLs, qANC3 qPAC12-2 anthocyanin content qAC12 ABTS will be useful marker-assisted breeding.
