Rice (Oryza sativa) genotypes with multiple pest resistance Pophaly D.J., Gupta Amol, Sahu G.R. Department of Entomology, Indira Gandhi Agricultural University, Raipur 492 012 (Madhya Pradesh). Abstract Seven new rice breeding lines out of 58 were found resistant/moderately resistant to major pests viz., Nilaparvata lugens, Orseolia oryzae and Xanthomonas campestris. Among these lines, R710-3-37-1-1-1 is resistant to all these three major pests and also possesses desirable grain and plant characters. Ruchi, a popular variety of this area is used as one of the donors in all seven crosses. Variety IET 6286 showed moderate resistance to Bacterial leaf blight disease (BLB) and brown planthopper (BPH) insect, is resistant to rice gall midge also. This genetic multiple pest resistant material is of great value in formulating the IPM programme for this region. Top Keywords Rice, breeding lines, multiple pest resistance, grain characters.
