A QTL study on late leaf spot and rust revealed one major QTL for molecular breeding for rust resistance in groundnut (Arachis hypogaea L.).

Late leaf spot (LLS) and rust are two major foliar diseases of groundnut (Arachis hypogaea L.) that often occur together leading to 50-70% yield loss in the crop. A total of 268 recombinant inbred lines of a mapping population TAG 24 x GPBD 4 segregating for LLS and rust were used to undertake quantitative trait locus (QTL) analysis.
