%X Late leaf spot and rust are the major biotic stresses in peanut worldwide. An effort was made to map late
leaf spot and rust resistance using the recombinant inbred line populations derived from TAG 24 x GPBD 4
and TG 26 x GPBD 4 in peanut. The new genetic maps were developed by mapping a large number of
Arachis hypogaea transposable element (AhTE) markers in addition to the previously mapped SSR
markers. A consensus map was generated based on these two independent maps, which was employed for
detecting the genomic regions governing late leaf spot and rust resistance measured at three stages (70, 80
and 90 days after sowing) in 12 seasons. Details of the quantitative trait loci identified from this study will
be disc ussed so as to use them in molecular breeding of peanut for improving late leaf spot and rust
resistance.
