A field experiment was conducted to screen out sixteen rice varieties against rice leaf folder at research farm of Birsa Agricultural University, Ranchi during Kharif season of 2019 and 2020.Out of sixteen varieties Suraksha, C. R. Dhan 304, C.R. Dhan 201 and PAC-801 emerged as resistant and promising against the leaf folder, receiving leaf damage due to leaf folder (LDLF) incidence below 10 percent even when they were grown in unprotected condition in the present studies as against the significantly and substantially higher pest incidence (i.e. LDLF %) recorded in case of TN- 1 and Lalat receiving 33.38 (32.45 & 34.32 per cent LDLF) and 23.60 (22.25 & 24.95 per cent LDLF) during both years respectively. Abhisek, C.R. Dhan 201, C.R. Dhan 304, PAC-801 and Suraksha were found resistant against the leaf folder incidence receiving incidence below 10 per cent. The genotypes IR-64 (Drt-1), BVD-203, Akshay Dhan, C.R. Dhan 303, Naveen, Vita-12, US- 362 and US-380 were moderately resistant.
