Conteúdo: 	The effects of four dwarfing genes on the high temperature tolerance at flowering were investigated. The genes were d-47(t) (dee-geo-wooo-gen dwarf), d-12 (yukara dwarf), d-18 (kotaketamanishiki dwarf). The following lines were used: the isogenic lines of Shiokari, i.e., d-47 line, d012 line, d-18 line and d-35 line, and the isogenic line of d-12 line showed higher spikelet fertilities but d-35 line showed lower spikelet fertility than Shiokari. At 37.C, d-47 (T65) line had some fertile spikelets (8.8%), although Taichung 65 had almost no fertile spikelet. It is recognized that d-47(t) enhaced the high temperature tolerance under the two genetic backgrounds with different tolerances. The olowing trend was shown: the more the germinated pollen grains per spikelet, the higher the spikelet fertility.
