Abstract: Ratooning rice has become a new rice planting style in Yangtze river area in recent years,and developed fast. Ratooning rice production is in coincidence with the reform requirement for reducing fertilizer and pesticide. But this rapidly developed trend has not been well supported by existing breeding programs. For this reason,the screening trials were conducted to compare and identify the well adapted rice varieties in Jianghan plain area,and the results could provide information for customers to choose right variety with mechanization adaptation.

Key words: ratooning rice, mechanized production, adaptability, Jianghan plain
