Three brown planthopper (BPH) resistant (Ratnachoodi, Rajamudi, JBT 36/14) and two susceptible donors (TN 1 and Jaya) of rice were studied at Department of Agricultural Entomology, ZARS, V. C. Farm, Mandya. The reaction of F2 populations of the crosses viz., Jaya × Rajamudi, Jaya × Ratnachoodi and TN 1 × JBT 3614 segregated in the ratio of 3:1 revealed that the resistance is governed by single dominant gene, while, Jaya × JBT 3614 and TN 1 × Ratnachoodi segregated in 13:3 interaction and TN 1 × Rajamudi in 9:7 indicating inhibitory and complementary gene action respectively. The parents Ratnachoodi, Rajamudi and JBT 36/14 can be used as source for easy incorporation of BPH resistance into susceptible high yielding rice varieties.
