In order to know the biological development characteristic and yield performance of the different rice varieties under warm climate in Yanbian area,41 rice varieties from domestic and overseas were tested.The results showed that the varieties of rice which growing season were in accord with non-frost period in Yanbian area showed prematurity,premature senility and less stimulation ratio when they met higher temperature during the early growth stage.While late ripen type of rice would bring heading stage earlier and the yields increased under same condition.Under the global warm climate,distributing rice varieties to different planting areas by forecasting correctly the changing trend of cumulative temperature was one of important measure to ensure stable yield in low temperature year and high yield in high temperature year in Yanbian area.
