A field experiment on screening of different garlic genotypes against thrips, Thrips tabaci Lind. was conducted at All India Co-ordinated Research Project on Vegetable Crops, Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Rahuri during Rabi 2014 and Rabi 2015 to ascertain relative susceptibility/resistance of different garlic genotypes to thrips, T. tabaci. The incidence of thrips varied among different garlic genotypes and mean thrips population ranged from 4.70 to 32.53 thrips per plant. Minimum mean number of thrips per plant was recorded in the genotype BG-110 (4.70 thrips/plant) whereas, maximum of 32.53 thrips per plant was recorded in the genotype AGSDRB-905. Considering the categorization for different garlic genotypes, BG-110, Phule Nilima and CG-113 had least mean thrips population of 4.70 to 5.53 thrips per plant and were grouped as highly resistant genotypes. The genotypes RHRG-53, RHRG-12, RHRG-33, CG-115, CSRG-1140, RHRG-30 and RHRG-14 were categorized as resistant genotypes with 10.33 to 16.54 thrips per plant. Besides these, the genotypes namely, CGSD-1263, RHRG-38, BGSD-1225, BGSDRB-906, CGSD-1249 and RHRG-25 recorded 17.87 to 25.02 thrips per plant and grouped as susceptible genotypes whereas, RHRG-1, CGSD-1245, RHRG-21 and AGSDRB-905 were graded under the highly susceptible category with 28.80 to 32.53 thrips per plant.
