Molecular screening of groundnut cultivars with validated TE marker for rust resistance
Author(s): Desai RS, Kolekar RM and Shinde BP
Abstract: Groundnut is one of the most important oilseed crops worldwide. Rust (Puccinia arachidis Speg.) is the major foliar fungal disease of groundnut which causes yield loss up to 57%. Besides traditional breeding, marker-assisted selection has been successfully initiated for the improvement of rust resistance in groundnut due to development of molecular markers, linkage maps and Quantitative Trait Loci (QTL) mapping. Trait specific markers are useful to hasten the selection of resistant genotype. In the present study, molecular screening of six groundnut genotypes (Phule Morna, Phule Unnati, Phule Warna, TPG 41, TAG 24 and GPBD 4) have been done with Arachis hypogaea Transposable Element (AhTE) based marker AhTE0498 which is closely linked to the QTL and validated for rust resistance. Allele for rust resistance was observed at high frequency among the four genotypes along with the resistant check GPBD 4. This trait specific marker can be employed in the marker-assisted breeding.
