Abstract: In order to discover the waterlogging tolerant varieties of pepper， the evaluation methodology of waterlogging tolerance of pepper was studied by the method of simulation in soil culture. According to the morphological changes under the waterlogging treatment， the level of waterlogging damage was classified into five grades. Five morphological criteria of leaf obscission， leaf color， leaf morphology， stem color and stem morphology were quantified via scoring. The waterlogging tolerance was identified by the comprehensive scores of the five criteria， then evaluation methodology was established. The waterlogging tolerance was identified in 34 pepper cultivars， the results showed that most of pepper cultivars were more susceptible to waterlogging which belonged to less tolerant class. Ten materials showing medium waterlogging tolerance and two materials showing highly waterlogging tolerance were screened out.
