objectives in groundnut. 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.","2020-06","published",,"Frontiers in Genetics (TSI)","11","514","Frontiers Media",,"1-15",,,,,,"doi:10.3389/fgene.2020.00514",,,,,"TRUE",,"1664-8021",,,,,,"","https://doi.org/10.3389/fgene.2020.00514","https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=10.3389%2Ffgene.2020.00514&btnG=","",,"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)","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
