Field experiments were conducted to screen different garlic genotypes against thrips damage and purple blotch disease during rabi 2016-2017. The infestation of thrips (5.78 to 9.55 thrips/ plant) and purple blotch disease incidence (4.00 to 65.20 PDI) varied among twenty-six garlic genotypes. Among genotypes, none showed highly resistance reaction against thrips infestation. Yamuna Safed, Ranebennur Local, Jamnagar Local, Mandsaur Local, GN-14-01, Ooty Local and Baram Local-06recorded thrips population (less than 6.93 per plant) were categorized as resistant. Yamuna Safed-8, Yamuna Safed-4, Bhima Purple, GN-14-27 and DWG-1 were highly susceptible against thrips (Mean population between 8.12 and 10.50thrips per plant). While, Bhima Purple, Yamuna Safed-2, Yamuna Safed-3, Yamuna Safed-4, Yamuna Safed-5, Yamuna Safed-8, Yamuna Safed-9, Baram Local-06, Jamnagar Local, Mandsaur Local, Ranebennur Local, Ooty Local, GRS-1330, GN14-25, GN14-15, DWG-2 and DWG-1 were found resistant against purple blotch disease. The similar performance was observed against thrips and purple blotch under laboratory conditions.
