Abstract

Micronutrient malnutrition affects more than one-half of the world’s population, especially women and pre-school children (Nestel et al., 2006). World Health Organization (WHO) of the United Nations estimated that mal nutrition is an underlying cause of 53% of all deaths in children under five years of age and recognized that the two micronutrients iron and zinc and pro-vitamin A (â-carotene) are limiting (Ma et al., 2008). Sorghum [Sorghum bicolour (L.) Moench], being the staple food and fodder crop in parts of semi-arid region of the world and the second cheapest source of energy (63.4 - 72.5 % starch) and micronutrients such as iron (Fe) and zinc (Zn) after pearl millet, if enriched with iron and zinc concentrations, can address the micronutrient requirements of the undernourished populations. Moreover, the poor and vulnerable groups in the society, particularly in India depend upon sorghum for their calorie and micronutrient requirement in the absence of access and affordability to nutrient-rich foods like vegetables, fruits and animal products. A study on association of grain iron and zinc concentrations with agronomic traits is needed to help the breeder in devising a suitable breeding strategy for the enhancement of micronutrient density in sorghum. Hence, this study was undertaken at ICRISAT, Patancheru with an aim to analyze the relationships of grain iron and zinc concentrations with grain yield and other agronomic traits in sorghum.
