Groundnut (Arachis hypogaea L.), is one of the most important oil seed as well as protein rich crop, grown all over the world. The present investigation was carried out for genetic analysis of yield and high oleic acid using allele specific molecular marker in 48 groundnut genotypes. Highly significant and positive correlation was found between number of pods per plant (r=0.399), number of seeds per plant (r=0.575) and harvest index (r=0.400) at 1% significance level. Assessment of high oleic acid content using gene-based markers was done using allele specific markers for FAD2A and FAD2B allele. The UPGMA clustering revealed that12 genotypes forming group with check variety Sunoleic 95R while 35 genotype formed separate groups. In selected lines total protein, oil and fatty acid was estimated using NIR spectroscopy. Total oil was ranging between 46 to 51%, linoleic acid 21 to 49 %, oleic acid 28 to 61%, palmitic acid 9 to 14%, stearic acid 1 to 3%, protein 18 to 31% and moisture level was between 2 to 11% for groundnut seed samples. The highest O/L ratio was in Sunoleic 95R and lowest in GPBD4. Screening of these advance lines and germplasms identified superior breeding material to be used for varietal improvement of groundnut.
