Groundnut (Arachis hypogaea) is an important cash crop of Pakistan. Groundnut has nutritional features like calcium, phosphorous, iron, zinc, proteins vitamin E and vitamin B complex. Little work has been done so far on groundnut quality aspects. Keeping this in mind present study was conducted comprising of eight groundnut genotypes collected from Barani Agriculture Research Institute (BARI) Chakwal which were evaluated for quality traits and their inheritance mechanism during Kharif season, 2016. Biochemical analysis for different traits were performed like protein content, oil content, calcium, phosphorous, iron, amino acid and Aflatoxin. The collected data were subjected to statistical analysis for ascertaining the significance of traits. Genotype 11CG005 gave good performance regarding oil content, iron content while genotype 11CG004 performed best for protein content and calcium content and it was also in safer limits for aflatoxin content. For phosphorous content, genotype 10CG008 gave best performance whereas genotype 11CG003 showed better results for amino acid content. High heritability with high genetic advance was showed by oil content, calcium content and protein content which indicated additive type of gene action for these traits while aflatoxin, amino acid, phosphorus and iron showed moderate heritability with little genetic advance which indicated predominance of non-additive type of gene action for the studied traits. The study is helpful in generating detailed information on quality traits of groundnut that can be used in future groundnut breeding programs of the country.
