A total eighteen rice cultivars were screened against false smut disease of rice under natural conditions in wetland field at Navsari during 2017 and 2018. Eighteen cultivars evaluated, out of seven cultivars viz., GNR-2, GNR-3, GNR-5, GNRH-1, Mahisagar, NAUR-1 and Dandi were found completely false smut free during 2017 and 2018. Whereas, highest per cent disease incidence i.e., 9.09, 7.02 and 8.06 per cent and disease severity index i.e., 15.00, 7.79 and 11.12 was found in cv.TN-1 whereas, highest average smutted ball i.e., 1.65, 1.11 and 1.
