Recombinant inbred line (RIL) and mutant populations of groundnut were employed to assess the utility of Arachis hypogaea transposable element (AhTE) markers, which detect the transposition polymorphism of Arachis hypogaea miniature inverted-repeat transposable element (AhMITE1), for the genetic and genomic studies to enhance the groundnut productivity. Of the two alleles (with and without AhMITE1 insertion) at each locus, the latter was more frequent (0.56) across 79 AhTE markers among the genotypes. Observed heterozygosity (HO) was higher for intergenic markers when compared to genic AhTE markers. Similarly, the AhTE markers from the A genome showed higher HO when compared to those from B genome. Mutant population in general showed the higher heterozygosity over the RIL population. AhTE markers displayed as high as 65.82% polymorphism, based on which the genotypes could be classified into two groups. Thus, the study indicated the usefulness of the AhTE markers in the genetic and genomic studies in groundnut.
