Anthocyanin and its co-relation with grain lipid in red grain deep water rice and scented rice land races of Assam

Red colouration of rice kernel has been found to be due to anthocyanin pigments in varied concentration in diverse groups of paddy viz. deep water rice (Bao dhan) and scented rice (Joha). Study has revealed that anthocyanin content has a strong positive co-relation (r = + 0.918 p >r_0.01) with lipid content. No such co-relation was found with the crude protein and total carbohydrate. However, even normal white kernels of both deep water rice and scented rice contain small but measurable amount of anthocyanin.
