| Abstract: | Zinc (Zn) malnutrition can be alleviated by increasing the dietary Zn intake through Zn biofortification of edible crops. Agronomic and genetic biofortification has been suggested as better option to increase the dietary Zn. In this study, we show considerable genetic variability for seed Zn concentration in six leading finger millet genotypes. External application of Zn resulted in improved Zn concentration in different plant parts; in particular there was significant increase in seed Zn concentration in all genotypes. Though genotypes GPU28 and INDAF5 showed differences in root and shoot Zn at vegetative stage but at reproductive stage there was no significant difference. Apart from that, Zn application increased the seed iron (Fe) concentration with no or minimal effect on copper (Cu) concentration. |
