Description 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.
