摘　　要：为发掘辣椒耐涝种质资源,对辣椒苗期耐涝评价方法进行研究。采用土培模拟涝胁迫的方法,根据涝胁迫过程中辣椒植株表型变化,将涝害指数分为5级。根据叶片脱落性、叶色、叶形态、茎色、茎形态5个外观指标,制定等级得分标准及评价方案,以各指标得分的总和对耐涝性进行综合评价,建立耐涝评价方法。对34个辣椒(Capsicum annum L.)品种进行苗期耐涝性鉴定,结果表明,辣椒品种对水涝较为敏感,大部分材料属于不耐涝品种,初步筛选出10份中度耐涝资源和2份耐涝性强的优异资源。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.
