Flavor improvement is one of the most important tasks in strawberry breeding. Fragaria nilgerrensis Schlecht has been widely concerned because of its special aroma components. There are abundant strawberry resources in southwest of China such as Sichuan, but the researches on its aroma components are not systematic. In this experiment, the aroma components of strawberry fruits from different geographical sources were analyzed. It could broaden the genetic background of cultivated strawberry and provide theoretical basis for innovative utilization of F. nilgerrensis Schlecht resources and breeding. In this study, headspace solid phase microextraction and gas chromatography-mass spectrometry (GC-MS) were used to analyze the differences of aroma components in six different geographical sources of F. nilgerrensis Schlecht. The results showed that a total of 89 aroma substances were detected. Different from the previously reported aroma components of cultivated strawberry, ester compounds did not account for the largest proportion in the other five geographical sources of F. nilgerrensis Schlecht, except Lijiang Yulong Snow Mountain. A total of 56 volatile substances with relative content greater than 1% were detected in this study, including 2 aldehydes, 19 hydrocarbons, 16 esters, 5 ketones, 4 alcohols, 5 amines and acids, and 5 other compounds. There were no common aroma components, and the aromatic components of F. nilgerrensis Schlecht were mainly esters and hydrocarbons, but they did not reach 50%. The aromatic components were mainly esters and hydrocarbons. The variety of aroma components of F. nilgerrensis Schlecht in Lijiang Yulong Snow Mountain was the most abundant, while that in Qinba Mountain of Wanyuan was the least. Among the aroma components measured, the first three with higher relative content were as follows: erythro-9,10-dibromopentacosane, dibutyl phthalate, benzeneethanamine. Cluster analysis and PCA analysis showed that the aroma components of F. nilgerrensis Schlecht in Yulong Snow Mountain of Lijiang were divided into a single cluster. Although they were both F. nilgerrensis Schlecht varieties, the aroma components were quite different due to geographical location and environmental characteristics. The influence of environment on the volatile compounds of strawberry needs further study.
