Extract

Brown planthopper, Nilaparvata lugens (Stal), is one of the most serious insect pests of rice (Oryza sativa L.) throughout Asia. Introduction of resistant varieties could be an effective means of minimizing losses from the pest. Several hundred rice cultivars resistant to the pest have been identified and the genetics of resistance has been analysed. Studies have shown that the genes for resistance to brown planthopper, bph-4, and to green leafhopper, Glh-3, are linked (Sidhu & Khush, 1979). Ideka & Kaneda (1983) reported that bph-2 for brown planthopper resistance was linked with the gene d2 for dwarfness. The present study sought to ascertain relationships between resistance to brown planthopper and tungro virus and grain characteristics.
