Abstract: The present study was conducted at Horticultural Research Farm, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during Kharif season 2015-16. The results of field experiments revealed that thrips population 20.78 nymphs and adult per plant were recorded during the second week of November (46th SMW). Thereafter, the nymph and adult population gradually declined to 2.14 per plant during the Third week of December (15th SMW). In the study, 40 genotypes of onion including check variety Agrifound dark red as susceptible check were evaluated against incidence of thrips, Thrips tabaci L., out of 40 genotypes, 8 genotypes were categorized as highly resistant, 10 as resistant, 17 as susceptible and 5 as highly susceptible to onion thrips. The genotype ON14-13 (3.03 thrips/plant) was considered as highly resistant followed by OSK-1306 (3.53 thrips/plant), ON14-01 (3.63 thrips/plant), and OSK-1301 (3.90 thrips/plant) because of lowest thrips population score and were superior with check variety Agrifound dark red. Genotype ON15-11 (17.64 thrips/plant) was highly susceptible than the check variety Agrifound dark red of onion.
