The field experiment was conducted with 18 groundnut genotypes in a randomized block design during kharif 2016. The study revealed that 5 genotypes from 18 genotypes acted as resistance, 3 as moderately resistance, 4 as moderately susceptible and 6 as susceptible. The genotypes ICGV-86699 (5.30) recorded the lowest population of thrips followed by TG-75(7.30), ICGV-07408 (7.95) and AK-335 (9.50) which shows resistance to the damage of thrips, while moderately resistance reaction was recorded by the genotypes ICGV-7211 (10.55), Dh.241 (10.60) and LGN-1 (8.40). The genotypes ICGV-07038 (11.35), GPBD-4 (11.40), ICGV-00203 (13.45) and Dh. 235 (12.25) showed moderately susceptible reaction. However the genotype which showed the susceptible reaction to thrips JL-24 (21.95) followed byICGV-86031(18.10), LGN-123 (16.90), LGN-176 (15.20) and VriGn-6 (14.75). Phenol content showed significant and negative correlation with thrips population (r = -0.830). Leaf water content (r = -0.982) and trichome frequency (r = -0.732) revealed negative and significant relationship with thrips population. Total sugar (r= 0.520) showed positive and significant relationship with thrips population. Whereas, leaf thickness (r= 0.151) showed positive but non-significant.
