The present invention relates to a non-derived FLC gene and their use in controlling the flowering time of a plant, the present invention using the plant, the expression of non-three kinds RsFLC genes derived from the respective control, blooming of the FLC gene plant it was confirmed that the time involved. Thereby, by using the three types of genes of the present invention can generate a plant with a plant of a flowering-time control. In the case of the horticultural products, to accelerate the flowering-time it is possible to increase the production volume by producing flowers and seed production in a short period of time.
