Abstract
An investigation was carried out on identification of superior recombinant inbred lines for high oleic content and pod yield derived from a cross GPBD-4 X GM 4-3 of groundnut. The experimental material comprising of 816 recombinant inbred lines in F7:8 generation was evaluated during 2011 and 2012 kharif seasons at Main Agricultural Research Station, University of Agricultural Sciences,Dharwad. These recombinant inbred lines along with parents and checks were grown in replicated trial and observations were recorded on pod yield, shelling percentage, 100 seed mass and oleic acid content in kernels was estimated using Near Infrared Spectrometry (NIRS).High oleic acid recombinant inbred lines were identified that were consistent in performance during 2011 and 2012 kharif seasons with 66 per cent to 74 per cent oleic acid content when compared to the parents GPBD-4 (50.2 %) and GM4-3(69%). Most of the high acid RILs recorded for pod yield (>2515 kg/ha) was on par with the high yielding check GPBD-4 but two recombinant inbred lines, RIL (438) and RIL(440) recorded higher pod yield. Both were on par with respective standard check GPBD-4 (>4157 kg/ha) but had extremely high oleic acid content (>66 %) compared to GPBD-4 (51 %) and both RILs were also resistant to foliar diseases, rust and late leaf spot.
