Abstract: The large panicle rice has important significance for increasing grain yield, with large sink capacity and high yield potential. Soil moisture and nitrogen management play a key role in the formation of grain yield and quality of rice during grain filling stage. To guide the cultivation of large panicle with high yield and quality, it has practical significance for study on the effects of soil moisture and nitrogen nutrient on mechanisms of large panicle rice. In this review, study of characteristics on large panicle rice in grain filling, the effects of soil moisture and nitrogen nutrient on large panicle rice in grain filling and its physiological analysis were summarized. The existing problems and further studies on large panicle rice were proposed.

Key words: large panicle rice, grain filling, soil moisture, nitrogen, physiological analysis
