The fundamental difference among early, middle and late rice lies in their different responses to light. Early and middle rice are insensitive to light and can mature normally all year round. Late rice is very sensitive to short sunshine, so it is strictly required that it can spend the photoperiod under the conditions of short sunshine and heading and fruiting. Late rice is very similar to wild rice, which is the basic type of direct evolution of wild rice, while early and middle rice are varieties of late rice differentiated under different temperature and light conditions. Rice in northern rice areas belongs to early rice or middle rice.
