Results: The results of the present investigation revealed that the rice varieties evaluated for their tolerance against Brown Plant Hopper (Nilaparvatalugens) and White Backed Plant Hopper (Sogatellafurcifera) showed varied reaction (Table. 2).  Based on effective tillers per hills it was observed that among the three variety of Paddy, Pratikhya showed highest no of effective tillers (17), Rajdeep obtained moderate no of tillers (16) and lowest no recorded in Swarna variety of paddy (14) respectively. Pratikhya var. (TO-I) showed comparatively more tolerance level (12%) and potential yield (52q/ha). Another two var. i.e  Rajdeep (TO-II) and Swarna (FP) recorded moderate to low tolerance.  Test weight of grain varied from 24 g to 23 g. Pratikhya var. of paddy is superior than Rajdeep and Swarna and its B:C ratio  2.48.  whereas another two var. Rajdeep and swarna showed B:C ratio 2.45 & 2.42. From the above investigation it may be concluded that (TO-I) was showed significant performance than TO-II and Farmers practice.
