  1. Mean concentration from the GC–FID reference analyses (Cons), cross-validated squared Pearson product-moment correlation coefficients (R2CV), Pearson correlation coefficients between the predicted fatty acids and total fat percentage (corr) and standard errors of the correlation, heritabilities (h2) and standard errors of the heritability for all calibrated traits. The concentration is expressed as percentage by weight of total fatty acid content (on a fatty acid methyl ester basis), except iodine value, which is expressed as g I2/100 g of total fatty acid content
