Abstract
Micronutrient malnutrition is one of the burning issues in rice-based diet area throughout world. Present study was aimed at evaluation of mineral composition of 77 rice landraces collected from various agro-climatic zones of Maharashtra. The hand mill processed rice grains were analyzed for eight (Na, Mg, K, Ca, Mn, Fe, Co, Cu and Zn) mineral content. Among the mineral contents, the iron content ranged from 2.05 to 12.2 mg/100g, calcium content from 39.2 to 238.47 mg/100g, manganese content from 1.53 to 7.54 mg/100g, copper content from 0.54 to 3.03 mg/100g and zinc content ranged from 2.65 to 11.62 mg/100g.The other minerals like magnesium content in studied landraces ranged from 81.72 to 278.56mg/100g, sodium content from 4.73 to 274.34 mg/100g and potassium content from 148.05 to 670.74 mg/100g. Most of the studied landraces had wide range of variation, rich in minerals and could be valuable source for bio-fortification of minerals through breeding method.
