Micronutrient deficiencies have been recognized in human which cause stunting in children, lower resistance to disease in both children and adults, and increase risks for both mothers and infants during childbirth. Micronutrients deficiency especially of Zn, Fe and Cu is also termed as hidden hunger. Their daily diet consists mostly of a few inexpensive staple foods, such as rice and wheat, which have traces of micronutrients. This study was carried out to explore information regarding mineral nutrient reserves in rice genotypes of different organizations. Rice grains of 60 genotypes were analyzed for these nutrients. The analytical results revealed that Zn ranged 12.5 to 26.3 mg per kg and 0.12 to 0.59 mug rice-1. Significant variation in Fe, Cu and Mn concentrations were also observed in rice grains of different genotypes. Iron, Cu and Mn concentrations ranged from 31.6 to 65.0, 5.90 to 14.3 and 34.8 to 64.2 mug g-1, respectively.
