A dwarf line, “Dwarf Hwacheong”, was induced from a japonica cultivar ‘Hwacheongbyeo’ by mutation in rice. Its agronomic characteristics, inheritance of dwarfness, and its response to exogenous gibberellin were studied. The dwarfness of the line was controlled by a single dominant gene, which was different from “D-53”, the only dominant dwarf-gene so far reported. The new gene was designated as “D-h”. The “D-h” gene was found to have the pleiotropic effect on short panicle and small-round grain. The dwarf line showed the similar response to GA₃ and GA₄₊₇ treatment with the original cultivar
