Field screening of 50 genotypes and varieties of rice against white-backed planthopper revealed that rice genotypes IR82475-110-2-2-1-2, Akshyadhan, and MTU-1010 recorded minimum population and TN1, Swarna, MTU 7029, Baranideep and Sahbhagidhan showed maximum population of the pest. Rice genotypes Akshyadhan, HUR-105, Sathi and IR 96248-16-3-3-2B showed the lowest amount of total sugar in leaves while, IR82475-110-2-2-1-2, Akshyadhan, NDR-97 and IR 96248-16-3-3-2B recorded highest total phenol contents. However, the maximum per cent of crude silica content was observed in Akshyadhan, IR 96248-16-3-3-2B, and Pantdhan-12. The rice genotypes IR82475-110-2-2-1-2, Akshyadhan, MTU-1010 and IR-96248-16-3-3-2B exhibited fair degree of resistance to white-backed planthoppers.
