The genetic control of rice resistance has been extensively studied, but how the resistance mechanism is genetically controlled has received less attention. This study revealed that the rice resistance mechanism toward brown planthopper was genetically controlled by several genes with several mendelian patterns. The tolerance mechanism is controlled by three complementary genes; this is confirmed by QTL analysis, whereas the Antibiosis is controlled by three separate loci on chromosomes 2, 8, and 11. The antixenosis was controlled by polygenic, but detected locus only on chromosome 3, with minor effects. © 2025 by the Korean Society of Breeding Science
