The use of markers linked to rust resistance are likely to aid in the selection of backcrossed progeny, the breaking of linkage drag, the pyramiding of multiple resitance loci, and in increasing the speed of selection. Previously, a linkage map has been published using a population derived from a cross between the single available accession of the most probable B genome ancestor of peanut, Arachis ipaënsis K 30076, and a highly rust-resistant accession of the closely related Arachis magna, K 30097 (Moretzsohn et al. 2009; Shirasawa et al. 2013). Here we report the identification of strong quantitative trait loci (QTL) linked to rust resistance and the development of single-nucleotide polymorphism (SNP) Kompetitive allele-specific polymerase chain reaction (KASP) markers suitable for foreground selection in breeding programs.","tracks":[]}
