摘要

Temperate rice genotypes represent a unique reservoir of phytochemical and mineral diversity that can enhance the nutritional value of rice-based diets. In this study, 150 rice genotypes (n = 150) from the North-Western Himalayas were evaluated for their nutritional and nutraceutical traits, including essential mineral (Fe, Zn) concentration and total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity. Dehusked seed minerals analysis revealed wide phenotypic variations i.e. iron and zinc content ranged between 13.20 ± 1.44 to 66.77 ± 1.75 ppm and 18.85 ± 2.55 to 55.56 ± 2.45 ppm respectively. Pigmented genotypes -particularly red and black rice exhibited significantly elevated TPC (up to 1563.59 mg GAE/100 g), TFC (up to 523.96 mg RE/100 g), and antioxidant activity (94.68%). Multivariate analysis separated mineral-associated traits from phytochemical and antioxidant attributes, with the first two principal components explaining 53.52% of the total variance. An SSR marker based marker-trait association analysis identified significant associations between RM240 and antioxidant activity, RM202 and grain iron concentrations and RM101 with total phenolic content and antioxidant activity. Collectively, this study integrates biochemical and molecular analysis to identify nutritionally superior Himalayan rice genotypes and provide SSR markers with potential application in marker assisted bio fortification and functional food oriented breeding program.
