    Abstract

    [Truncated abstract] A low concentration of micronutrients in the diet causes micronutrient malnutrition globally, increases mortality and morbidity rates and reduces the quality of life. Dietary diversification, nutrient supplementation and food fortification are effective against micronutrient malnutrition but have limited success in rural regions of developing countries due to poverty and food habits. Biofortification, an agriculture-based approach, can reduce micronutrient malnutrition especially in rural areas of developingcountries.

    Biofortification is the production of micronutrient-dense crops by means of agronomic management and/or plant breeding. Recent biofortification programs have focused on iron, zinc and vitamin-A. Yet there are other important elements that need attention such as selenium (Se). Selenium is a constituent of selenoproteins, enzymes and antioxidants. Globally over one billion people suffer from Se deficiency. Lentil may be an effective vehicle to supply dietary Se to affected populations. This study to design a biofortification strategy for lentil used a baseline survey in farmers’ fields in Bangladesh and designed field experiments in Bangladesh and Australia to unravel genotypic and environmental effects on seed Se concentration and to evaluate foliar Se application.
