An experiment was conducted at College of Agriculture, Nagpur to screen forty different groundnut genotypes against tikka disease of groundnut during kharif, 2016-17 in randomized block design with three replications. Biochemical constituents of phenol, total sugar and chlorophyll at 45-50DAS (flowering stage) and 90DAS (pod development stage) were estimated from leaves of healthy and diseased samples. Forty genotypes of groundnut were screened for tikka disease under field condition. None of the genotypes were found to be immune to early leaf spot. Two entries (ACNGV-25, ACGGV-30) were highly resistant, seven entries (Kopergaon-3, 3, 10, 14, ACGGV-27, 36, 38) were resistant, fourteen entries (ACNGV-2, 5, 8, 9, 11, 13, 18, 26, ACGGV-28, 29, 31, 33, 34, 35) were moderately resistant, thirteen entries (ACNGV-1, 4, 6, 7, 12, 15, 17, 19, 21, 22, 23, 24, ACGGV-32 were susceptible) and four entries (ACNGV-16, 20, ACGGV-37, TAG-24) were highly susceptible to the early leaf spot. Similarly none of the genotypes were found to be immune and highly resistant to late leaf spot disease. One entry (Kopergaon-3) was resistant, one entry (ACGGV-30) was moderately resistant, thirty six entries (ACNGV-1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 18, 19, 20, 21, 22, 23, 24, 25, 26, ACGGV-27, 28, 29, 31, 32, 33, 34, 35, 36, 37, 38, TAG-24) were susceptible and two entries (ACNGV-16, 17) were highly susceptible to the late leaf spot.
