A population of 53 mutants, their parents and eight cultivated varieties belonging to two subspecies of groundnut were evaluated during kharif 2012 for productivity, oil quality traits and resistance to late leaf spot (LLS) and rust diseases to assess association between these traits and the Arachis hypgaea Miniature Inverted-Repeat Transposable Elements (AhMITE1) markers. Genotypes showed significant differences and high PCV and GCV for all the traits. Of the 41 transposable elements (TE) markers used for genotyping the population, 24 showed high to moderate genotype discriminating power in terms of polymorphism information content (PIC). Single marker analysis revealed significant association of AhTE205 with number of pods per plant, pod yield per plant and shelling percentage. While the other markers that should significant association are AhTE333 with test weight, AhTE343 with LLS (90 DAS), AhTE373 with oil content (%) and AhTE211 with oleate content and O:L ratio. These markers need to be validated for their trait association before they are employed for groundnut improvement.
