摘要： Strawberry (Fragaria x ananassa) is an important horticultural crop and is highly nutritious and valuable. However, several molecular mechanisms on the biosynthesis and metabolism of aroma compounds and the regulatory network that governs aromas remain unknown. This study investigated the influence of different altitude ecotypes on the components of pulp aroma and volatile metabolites in strawberry hybrid F-1 and its parents. "Perilla alcohol" was found to be the major factor that regulated the aroma of strawberry pulp from plants at low altitudes, and "perilla alcohol, linalool, alpha-farnesene and E-2-hexenyl benzoate" were the major factors that regulated the aroma of strawberry pulp from plants at high altitudes. Furthermore, three key candidate genes were identified according to the criteria of |K.i| > 40 and |MM| > 0.90. This study will establish a theoretical foundation for the cultivation of novel varieties of strawberries characterized by superior quality and flavor.
