deterioration of fodder quality in groundnut worldwide. High oleic acid has emerged as a
key market trait in groundnut, as it increases the shelf life of the produce/products in
addition to providing health benefits to consumers. Marker-assisted backcrossing (MABC) is
the most successful approach to introgressing or pyramiding one or more traits using traitlinked
markers. We used MABC to improve three popular Indian cultivars (GJG 9, GG 20, and
GJGHPS 1) for foliar disease resistance (FDR) and high oleic acid content. A total of 22 BC3F4
and 30 BC2F4 introgression lines (ILs) for FDR and 46 BC3F4 and 41 BC2F4 ILs for high oleic acid
were developed. Recurrent parent genome analysis using the 58 K Axiom_Arachis array
identified several lines showing upto 94% of genome recovery among second and third
backcross progenies. Phenotyping of these ILs revealed FDR scores comparable to the
resistant parent, GPBD 4, and ILs with high (~80%) oleic acid in addition to high genome
recovery. These ILs provide further opportunities for pyramiding FDR and high oleic acid in
all three genetic backgrounds as well as for conducting multi-location yield trials for further
evaluation and release for cultivation in target regions of India.","2020-02","published",,"The Crop Journal (TSI)","8","1","KeAi",,"1-15",,,,,,"doi:10.1016/j.cj.2019.07.001",,,,,"TRUE",,"22145141",,,,,,"","https://doi.org/10.1016/j.cj.2019.07.001","https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=Improvement+of+three+popular+Indian+groundnut+varieties+for+foliar+disease+resistance+and+high+oleic+acid+using+SSR+markers+and+SNP+array+in+marker-assisted+backcrossing+&btnG=","pub",,"","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
