The invention discloses a method for directionally breeding different photosensitive rice, which controls expression and/or silence of Hd1 gene, Ghd7 gene, DTH8 gene and/or PRR37 gene in rice, and directionally breeds photosensitive rice and/or weak photosensitive rice. The rice is photosensitive rice, and an Hd1 gene, a Ghd7 gene, a DTH8 gene and a PRR37 gene are expressed in the rice; the rice is weak photosensitive rice, and an Hd1 gene, a Ghd7 gene and/or a DTH8 gene are knocked out and/or silenced in the rice. On the basis of the method, the heading effect of the hybrid rice can be predicted by identifying the heading photosensitive gene combination of the hybrid rice parents, parent matching is effectively guided, and directional breeding of specific photosensitive type rice plants is achieved. 本发明公开了一种定向培育不同感光型水稻的方法，控制水稻中Hd1基因、Ghd7基因、DTH8基因和/或PRR37基因的表达和/或沉默，定向培育感光型水稻和/或弱感光型水稻；所述水稻为感光型水稻，在水稻中表达Hd1基因、Ghd7基因、DTH8基因和PRR37基因；所述水稻为弱感光型水稻，在水稻中敲除和/或沉默Hd1基因、Ghd7基因和/或DTH8基因。基于所述方法能够通过鉴定杂交稻亲本的抽穗感光基因组合预测杂交稻的抽穗效应，
