Popis:	Five groundnut (Aruchis hypogueu L) cultivars developed by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and two local cultivars as controls were grown in post-rainy and rainy seasons at Patancheru, India. They were analysed for their proximate composition, minerals and trace elements, amino acid composition, true protein digestibility (TD), biological value (BV), net protein utilisation (NPU), and protein efficiency ratio. One-hundred seed mass, protein content and TD were significantly higher in the post-rainy season while starch, sugars, BV and NPU were significantly higher in the rainy season. Post-rainy cultivars exhibited higher concentrations of potassium, calcium, iron and several essential and non-essential amino acids. TD of blanched groundnut was better than that of the whole seeds. The composition and protein quality of ICRISAT cultivars were comparable to those of the controls.
