Table II.

Percentage of total variation accounted for by the different variance components in the genepool diversity assessment, for the different fatty acids

The modern oilseeds were excluded from this analysis. Significance of variance components other than between samples was assessed by comparing the change in deviance between models including the component and those excluding it to a χ² distribution on the appropriate number of degrees of freedom. Significance levels are shown as follows: ***, <0.1%; **, <1%; *, <5%.
