Abstract：Drought tolerance was investigated during seedling stage with repeated drought stress.Two hundred and one foxtail millet varieties were classified into 5 groups as extremely drought tolerance,drought tolerance,moderate drought tolerance,less drought tolerance and no drought tolerance based on seedling sur-vival rate.The 15 varieties had the extremely drought tolerance,which occupied 7.46%.The 48 varieties had drought tolerance,which occupied 23.88%.The 80 varieties had moderate drought tolerance,which occupied 39.80%.The 47 varieties had less drought tolerance,which occupied 23.38%.The 11 varieties had no drought tolerance,which occupied 5.47%.The average seedling survival rate of 201 varieties was 71.02% under drought stress with the variation range of 1.05% to 100.00%.The variation range of relative seedling height was from 23.92% to 95.00%.That of relative biomass range was between 11.37% and 83.10% with the variation coefficient of 50.98%.The seedling survival rate had extremely significant correlation with the relative seedling height and relative biomass and significant correlation with the relative fresh weight.
