IR-8 is a high yielding semi-dwarf variety of rice that was developed by the International Rice Research Institute (IRRI), Philippines. In 1962, breeders at IRRI made crosses to introduce dwarfing genes from Taiwanese varieties such as Dee-geo-woo, Taichung Native 1 and Igeo-tse to tropical tall land races. In 1966, IR8, the first semi-dwarf, high yielding rice variety, was released for the tropical irrigated lowlands.
Hence, the correct answer is ‘Philippines’.
