Abstract: The male-sterile outcrossing progenies of IR36ms, the monogenic male-sterile rice line with stable sterility under various environmental conditions, have the same characteristics in male-sterile as IR36ms with whitish shrivelled anthers and no pollen. The anthers of the progenies of IR36ms, treated with the chemical restoration agent X No. 1 around the meiosis stage, changed to yellow and plumpness. The male-fertility were partially restored to different extent with the highest 50% fertile pollen. Some seeds from self-crossing of the rice were obtained.

Key words: fertility restoration, genic male-sterility, plant growth regulator
