Summary
The inheritance of resistance to white-backed planthopper, Sogatella furcifera Horvath, was investigated in a rice, Oryza sativa L., cultivar N22. Resistance to the white-backed planthopper in the cross IR30×N22 appears to be governed by a single dominant gene-designated Wbph. The classification for various characteristics of 397 F3 families of the IR30×N22 cross confirmed earlier results about the monogenic dominant control of resistance to brown planthopper, green leafhopper, and bacterial leaf blight, and about the monogenic recessive control of short stature. Additionally, the genes governing plant height and resistance to white-backed planthopper, brown planthopper, green leafhopper, and bacterial leaf blight were found to segregate independently of each other in these 397 F3 families.
