Rust and LLS cause significant economic loss, and high oleic trait is an industry preferred trait that enhances economic returns. This study reports marker-assisted selection to introgress high oleic content, resistance to LLS and rust into Kadiri 6 (K 6), a popular cultivar. The alleles for target traits were selected using linked allele-specific, simple sequence repeats and single nucleotide polymorphic markers. The F1s (384), intercrossed F1s (441), BC1F1s (380), BC1F2s (195), and BC1F3s (343) were genotyped to obtain desired allelic combination. Sixteen plants were identified with homozygous high oleic, LLS and rust resistance alleles in BC1F2, which were advanced to BC1F3 and evaluated for disease resistance, yield governing and nutritional quality traits. Phenotyping with Near-Infrared Reflectance Spectroscopy identified three lines (BC1F3-76, BC1F3-278, and BC1F3-296) with >80% oleic acid. The identified lines exhibit high levels of resistance to LLS and rust diseases (score of 3.0–4.0) with preferred pod and kernel features. The selected lines are under yield testing trials in multi-locations for release and commercialization. The lines reported here demonstrated combining high oleic trait with resistance to LLS and rust diseases. date: 2020-06 date_type: published publication: Frontiers in Genetics (TSI) volume: 11 number: 514 publisher: Frontiers Media pagerange: 1-15 id_number: doi:10.3389/fgene.2020.00514 refereed: TRUE issn: 1664-8021 official_url: https://doi.org/10.3389/fgene.2020.00514 related_url_url: https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=10.3389%2Ffgene.2020.00514&btnG= funders: This work is supported by the OFID, Department of Agriculture and Co-operation (DOAC), Ministry of Agriculture, Government of India, and CGIAR Research Program on Grain Legumes and Dry Land Cereals (CRP-GLDC) citation: Deshmukh, D B and Marathi, B and Sudini, H K and Variath, M T and Chaudhari, S and Manohar, S S and Rani, C V D and Pandey, M K and Janila, P (2020) Combining High Oleic Acid Trait and Resistance to Late Leaf Spot and Rust Diseases in Groundnut (Arachis hypogaea L.).
