Among the legumes, mungbean has highest digestive protein but low micronutrient content like iron and zinc. Biofortification
of mungbean has been undertaken to reduce micronutrient malnutrition. The objectives of this study were to identify QTLs
for seed Fe and Zn content in F6 recombinant inbred line (RIL) population (ML776 x Sattya). A large genetic variation and
transgressive segregation in RILs were observed for Fe and Zn content. Linkage map was developed which spanned
2919.7cM distance. 17 QTLs (2 for iron and 15 for zinc content) were mapped on four linkage groups; LG 4, LG 6, LG 7
and LG 11 in mungbean. The genomic regions qZn-4-3 and qFe-4-1 on chromosome 4 between PVBR82-BM210 markers;
qZn-11-2 and qFe-11-1 on chromosome11 between BM141-BM184 markers, were co-located on the same chromosomal
regions for Zn or Fe concentration, which probably were closely linked to each other, or were the same pleiotropic QTLs.
The SSR markers associated with QTLs for both high iron and zinc content would also be useful in marker assisted
breeding for biofortification in mungbean.
