To evaluate and compare the physicochemical traits, proximate nutrient composition, and micronutrient concentrations of regional red rice (Oryza sativa L.) varieties.
Evaluated grain dimensions, shape classifications, and amylose content across red rice varieties collected from four mountainous districts (Shimla, Kullu, Chamba, and Kangra).
Quantified proximate composition parameters, including moisture, ash, crude protein, carbohydrate, and energy values.
Measured iron and zinc trace mineral concentrations and calculated correlation coefficients among proximate and energetic traits.
Amylose content spanned from 18.27% (Karad) to 25.17% (Chhohartu), while crude protein content ranged from 8.66% (Jhinjhan) to 13.89% (Gocha).
Trace mineral analysis showed striking differences, with iron ranging from 83.6 mg/kg (Karad) to 402.2 mg/kg (Jhinjhan) and zinc ranging from 32.35 mg/kg (Matali) to 46.55 mg/kg (Kaluna).
Significant negative correlations occurred between carbohydrate and protein (r = -0.810**), energy and moisture (r = -0.877**), and energy and ash (r = -0.711*).
