By using different genotype of rice varieties （strains） suitable for cultivation in cold region as experimental materials, the effects of light on the growth of rice seedlings were studied by setting different light quality and light intensities with LED lights at seedling stage, in order to provide reference for indoor cultivation of rice in cold region in winter. The results showed that the effects of two light quality treatments on rice seedlings were similar; the responses of different rice varieties（strains） to light were different, but after increasing light intensity, the leaf age of rice seedlings accelerated, the number of roots increased, the base stem width, shoot dry weight, root dry weight and the seedling index increased. Strong seedling could be cultivated by appropriate increase of light intensity. Compared with the control, the quality of rice seedlings was poor when the intensity was about 1700 lx; when the intensity was about 3500 lx, the quality of rice seedlings was similar; when the intensity was about 5300 lx, the quality of rice seedlings was significantly improved.
