Abstract:

Micronutrient malnutrition is a serious health concern resulting due to deficiency of minerals such as iron and zinc in dietary intake. Genetic enhancement of crops with higher mineral content i.e. bio-fortification is one of the most cost effective method to solve the global mineral malnutrition problem. In the present investigation, experiments were conducted to evaluate BC1F2 and BC1F3 populations derived from cross between PAU201 (high-yielding) and Palman 579 (iron-rich) indica rice varieties for various physio-morphological traits and minerals (iron and zinc) content. Iron and zinc content varied from 0.9- 130.5 and 0.8-143.1 µg/g in BC1F2 and BC1F3 populations, respectively. The results of phenotypic correlation analysis showed positive correlation (r=0.281) between grain iron content and zinc content in BC1F2 population but not in BC1F3 population. The frequency distribution bar diagrams for micronutrient content and frequency distribution curves for various physio-morphological traits, iron and zinc content of PAU201 × Palman 579 derived BC1F2 and BC1F3 plants along with parental rice genotypes were accessed.
