A new recombinant inbred line (RIL) population was developed from a late leaf spot (LLS) susceptible mutant (VL 1) and its secondary mutant (110) which was resistant to LLS. The RILs (114) were evaluated for yield, yield components, nutritional and oil quality traits, and response to LLS and rust diseases during the rainy season of 2015 to assess the suitability of the mapping population for mapping these traits. The RILs differed significantly for all the traits studied. Phenotypic coefficient of variation and genotypic coefficient of variation were moderate to high for pod yield, number of pods per plant, pod weight per plant, shelling percentage, test weight, protein, oleic to linoleic acid ratio, kernel yield, oil yield, and LLS and rust score at 70, 80 and 90 days after sowing (DAS). The RILs exhibited normal distribution for all the studied traits except for rust score at 80 and 90 DAS, and shelling percentage. VL 1 and 110 despite being the primary and secondary mutants, showed polymorphism in terms of SNP, CNV and transposable element insertion. Therefore, this RIL population could be of importance for mapping the agronomic and productivity traits.
