Values were calculated from the results of an ANCOVA with ln-transformed amounts (in ng/h) as dependent variable, line (L) and replicate (r) as independent variables, and shoot dry weight (m) and total emission (z; for relative amounts) as covariates. Abbreviations for probability levels: ^*, <0.05; †, <0.01; ‡, <0.001; §, <0.0001; σ², genetic variance; CV, coefficient of variation; Rt, retention time; MS, mass spectrum; 1, monoterpenoids; 2, esters (acetates); 3, homoterpenes; 4, N-aromatics; 5, sesquiterpenoids.

^aMS similar to that of α-zingiberene, in some cases (e.g. Delprim, F2) coelution of another sesquiterpene, most probably β-elemene (MS).

^bMS similar to that of α-zingiberene.

^cMS similar to that of β-sesquiphellandrene, in several cases (e.g. Du101, F476) coelution of another sesquiterpene, most probably δ-cadinene (MS).
