Variability in Fe and Zn content among Indian wheat landraces for improved nutritional quality

Published on

The short-term agricultural tools like agronomic biofortification of available nutrient resources are an emerging
cost-effective strategy to address global malnutrition,
especially in developing countries. This strategy involves
supplying of micronutrients such as iron and zinc in the
staple foods by using conventional plant breeding and
biotechnology methods. The present study was to estimate
iron and zinc in 180 Indian wheat landraces obtained from
National Bureau of Plant Genetic Resources, Delhi.
Substantial variations among 180 lines existed for both
iron and zinc contents. Iron concentration ranged from
32.7 µg/g to 54.5 µg/g and zinc concentration from 15.8 µg/
g to 66.3 µg/g in wheat landraces. Iron and zinc
concentration were positively correlated implying the
chance for concurrent selection for both the micronutrients.
Six potential landraces, namely, IC-82198, IC-532790, IC-
534886, IC-532310, IC-82377 and IC-79062 having high
amount of both Fe and Zn content have been identified.
Micronutrient-rich genotypes identified in this study opens
up the possibilities for the identification of genomic regions
or QTLs responsible for mineral uptake and translocation
that can be used as donor for developing nutrient enriched
varieties.
