The PCA of the free and bound volatile compounds after 2 years, contained in the F1 hybrid population (Pop AC). a The first two-component scores of individuals harvested in 2014 (open circles) and 2015 (closed circles). b Corresponding loading plot of the variables, showing the positions of the volatiles classified as lipid derivatives (green), shikimic acid derivatives (black), terpenoids (blue) and norisoprenoids (red). Selected variables to interpret the score plot are labelled on the loading plot
