Abstract：In order to select excellent drought resistance germplasms,111 pepper lines were used as materials to identify and evaluate drought resistance of pepper lines by repeated drought survival rate at seedling and adult plant stages respectively under the condition of floating seedling.There were 9 lines and 6 lines that repeated drought survival rate were equal to or more than 70.00％ (RDSR≥70.00％) at seedling stage and adult plant stages respectively accounting for 8.11％ and 5.41％ of the tested lines.The average repeated drought survival rate of seedling stageand adult plant stages of 4.50％ lines was equal to or more than 70.00％ (RDSR≥70.00％).‘gx2016-25’ ‘gc2016-33’and ‘gc2016-69’ were screened as lines with good drought resistance at seedling stage and adult plant stages by overall consideration of the analysis results of repeated drought survival rate at seedling stages,adult plant stages and average repeated drought survival rate of this two stages.
