The results showed that the variety for single cropping rice needed total accumulated temperature about 3600 C during total growth period in Shanghai, was early maturity and later nonwaxy rice, there were eighteen complete leaves druing total growth period, the leaf age was obvious changes in different seeding stages, the tillering capacity of the variety was thinner,elongation node was five, caudex internode was dense and strong, elongation and young panicle differentiation began at same time, the panicle was bigger, but lax, setting rate changed with changes of environment during the milk stage.
