【摘要】 为快速、便捷、准确地筛选出辣椒耐涝资源，以多种类型辣椒纯系种质资源为试验材料，在辣椒漂浮育苗生理苗龄达到4～6片叶时，采用模拟极端淹水处理，经过形态学统计分析，构建辣椒耐涝性评价体系，并对辣椒种质资源进行鉴定。结果发现，不同的辣椒种质资源在淹水条件下，其根、茎、叶表现出不同的表型特征，其表型特征依据淹水条件下受害程度进行赋值，通过分类统计，可以归为强耐涝、耐涝、敏涝、极敏涝4类。结果表明，该评价体系能够准确的筛选出耐涝资源，与结果期田间耐涝处理表现一致，具有较好的稳定性。通过该评价体系对101份辣椒资源进行鉴定，鉴定出强耐涝资源gc2016-41、极敏涝资源gc2016-39。更多还原

【Abstract】 In order to quickly,conveniently and accurately screen the excellent pepper germplasm with waterlogging tolerance,the pepper inbred lines were selected as experimental materials.The evaluation system of pepper waterlogging tolerance was established through morphological analysis of pepper seedlings with 4-6 leaves suffering extreme flooding.The results showed that the roots,stems and leaves of pepper germplasm resources exhibited different phenotypic characteristics under flooding stress.According to the phenotypic characteristics in response to flooding,the germplasm resources were classified into four categories,namely strong waterlogging tolerance,waterlogging tolerance,waterlogging sensitivity and extreme waterlogging sensitivity.The evaluation system could accurately identify resources with waterlogging tolerance,which was consistent with the field performance of pepper suffering waterlogging stress at fruit-setting stage.A total of 101 pepper resources were tested using the evaluation system.The germplasm gc2016-41 and gc2016-39 exhibited strong waterlogging tolerance and extreme sensitivity,respectively.更多还原
