Author(s): Kale GB, Karnewar SD, Dhawale RN and Dubey VK

Abstract: In all 121 promising rice genotypes of IGAU were evaluated against brown plant hopper (BPH) in glasshouse by adopting internationally accepted screening technique out of these genetic stock, three genotypes were found to be resistant and 20 were moderately resistant whereas, 98 genotypes were susceptible to brown planthopper infestation. In depth studies of different rice category revealed that resistant rice genotypes had the least feeding values 24.75 to 39.00 mm2 with the highest numbers of probes 25 to 40 per seedling in 24 hours feeding duration with vice versa in susceptible rice genotypes.
