Study on Screening of Drought Resistant Late Rice Varieties

A drought stress experiment was conducted by pot culture with artificial rain shelter with 8 rice varieties as materials which applied in large area in Hunan province.The drought resistance of 8 varieties was compared by examining relative content of chlorophyll,free proline content and main agronomic traits under different water conditions at active tillering stage and booting stage.The results showed that drought resistance of Xiangfengyou No.9,Yueyou 9113 and Yueyou 6135 was stronger.In order to determine the actual drought resistance of above 3 varieties,the field experiment would be conducted.
