The present inventors successfully isolated a photoperiod sensitivity gene Hd6 from rice by a linkage analysis. It was revealed that the photoperiod sensitivity of plants can be modified by introducing the gene or controlling the expression of the gene. Further, it was demonstrated that the photoperiod sensitivity of plants can be assessed by detecting the presence or absence of the functional gene.
