Abstract
An experiment was conducted to screen out twenty-three rice cultures, varieties and genotypes against rice gall midge (biotype-3) at the research farm of Birsa Agricultural University, RAC (Ranchi Agriculture College) Kanke, Ranchi during kharif season of 2017. Out of 23 genotypes, Kavya, W-1263, Abhaya, Phalguna, Lalat, BG-380-2, RD-202 and Suraksha emerged as resistant and promising against the gall midge (biotype-3), receiving silver shoot incidence below 5% even when they are grown in unprotected condition in the present studies as against the significantly and substantially higher pest incidence (i.e. SS%) recorded in case of TN- 1, IR-64 Sub-1 and IR-64 receiving 32.49%, 20.15% and 19.33%, respectively. Naveen was responsible for realization of the highest grain yield (52.70 q/ha) among all the tested rice varieties.
