An experiment was conducted to assess the agronomic performance of groundnut varieties viz., CO-6, Kadiri-9, ICGV-91114 in comparison with farmer's preferred variety TMV-7 under rainfed condition in farmers' fields in Dharmapuri district, Tamil Nadu during kharif 2015. The result showed that the variety Kadiri-9 exhibited superiority in respect of higher dry matter production (40.3 g/plant), number of pods per plant (28.8) and pod yield (1632 kg/ha) and accrued higher net income (`.26670/ha) and benefit cost ratio (2.03). The varieties ICGV-91114, TMV-7 and Kadiri-9 were early in terms of days to 50 per cent flowering and maturity. The varieties CO-6 and Kadiri-9 were found tolerant to major pests and diseases like leaf miner, collar rot and late leaf spot.
