Identification of molecular markers revealing polymorphism among the parental lines are prerequisite for mapping
QTLs and genes for desired traits. The genomic regions which contributes to the accumulation of grain iron and zinc
in rice could greatly help in rice bio fortification programs. A BC4
F10 mapping population was earlier developed from
the cross between an elite fine-grain Oryza sativa indica cultivar, BPT5204 and a wild progenitor specie O. rufipogon
WR119. A total of 800 randomly selected SSR markers distributed on all the 12 chromosomes of rice including 50 gene
specific markers related to grain iron, zinc and yield traits were used to identify the polymorphic loci between the two
genotypes. In all, 166 markers (20.75 %) showed distinct polymorphism. 149 SSR markers (19%) out of 750 SSRs and
17 out of 50 gene-specific markers (36%) were polymorphic. The 17 polymorphic gene-specific markers were related
to gene families OsZIP, OsYSL, OsNRAMP, OsNAAT, OsFRO, OsFDH, OsGSTU and OsPDR which are involved in
metal transport and homeostasis in rice. Among the markers reported to be significantly associated with QTLs for
grain iron, zinc and yield related traits, RM517, RM81A, RM264, OsYSL-7, RM5460, RM3874 were polymorphic in
this study
