Abstract: To collect samples and information, the drought-resistant germplasms of Oryza rufipogon Griff, which are indigenous to Hainan, at the seedling stage underfield conditions as well as at heading stage in a plastic shed were indentified.The results showed that 672 accessions were drought resistance under field conditions,and 25 accessions and 2 accessions respectively were high drought resistance at the seedling stage and heading stage.They were collected from Wenchang,Haikou, Wanning and Chengmai. The results would provide a reference for further study and breeding of new drought-resistant rice varieties in the future.

Key words: Oryza rufipogon Griff in Hainan, drought resistance, seedling stage, heading stage, identification, selection
