Fourteen raspberry varieties were evaluated over two cropping seasons by solid-phase microextraction (SPME) followed by gas chromatography-mass spectrometry. Thirty-six compounds were fully identified, and 10 more compounds were tentatively identified. Despite interannual variability, raspberry varieties can be divided in two main groups on the basis of terpenes and C-13 norisoprenoids. Susceptibility toward Botrytis cinerea, one of the most relevant pathogenic fungi for soft fruits during storage, was also evaluated. On the basis of volatile profiles, it was possible to highlight the relationship between different volatile compounds and resistance to B. cinerea. Volatile profiles and Botrytis susceptibility of the different raspberry varieties evaluated should assist future breeding programs.
