EVALUATION OF TRADITIONAL RICE GENOTYPES OF MANIPUR FOR THEIR RESISTANCE AND SUSCEPTIBLE REACTION AGAINST RICE LEAF FOLDER.

Different local Manipuri rice genotypes were screened out to find their resistance reaction against rice yellow stem borer during kharif 2018 at College of Agriculture, CAU farm. The average infestation of leaf folder from vegetative stage up to near maturity of the crops ranges from 2.32 per cent damage leaves to 6.14 per cent damage leaves. The lowest infestation was recorded in Khaenoh and the highest in standard check. The average lowest incidence of rice leaf folder was observed in the rice genotypes Khaenoh (2.32 per cent leave damage), Phouren Noining (2.37 per cent leaf damage), Niirui (2.57 per cent leaf damage), Shangao (2.72 per cent leave damage), and Langphou (2.85 per cent leaf damage) in ascending order. Among the different rice entries, the average highest percent leaf damage leaves due to leaf folder infestation was observed in Kikhu (5.47 per cent leaf damage), Mashi Manui (4.94 per cent leaf damage), Mileing Manthowean (4.76 per cent leaf damage), Tathai (4.71 per cent leaf damage) and Naga Buh (4.61 per cent leaf damage) in descending order.
