摘　　要：为了估测番茄种质资源外观果实性状对番茄果实中番茄红素含量和可溶性固形物含量构成的相对重要性,在对番茄种质资源数量性状相关性分析的基础上,对50份国内外番茄种质资源的10个果实外观性状与2个内在品质性状进行了通径分析。结果表明:果梗洼大小、果柄长度、果实硬度对于番茄果实番茄红素含量和可溶性固形物含量的直接效应较大,且受其它性状的间接影响较小。In order to estimating the relative importance of the appearance of tomato fruit characters in lycopene content and soluble solids content structure, path analysis on 10 appearance of tomato fruit characters and the internal fruit quality traits after the correlation analysis in tomato quantitative traits was analyzed. The results showed that the characters as the size of pedicel scar, pedicel length and fruit hardness had larger direct effects to lycopene content and soluble solids content, and others had little indirect effects to those characters.
