  1. GBLUP  genomic best linear unbiased prediction; MGBLUP  metabolomic-genomic best linear unbiased prediction; LOYO  leave one year out
  2. FS  filtering speed, EY  extract yield, WC  wort color, BG  beta-glucan, WV  wort viscosity
  3. GBLUPg is GBLUP incorporating genotypes on lines in VP, and MGBLUPg is similarly defined
  4. “cor” columns show the correlations between predicted breeding values and corrected phenotypes for lines in VP, and “reg” columns show the regression coefficients of corrected phenotypes on predicted breeding values
  5. *Denotes that for the given trait, the difference between the two correlations is statistically significant using a Hotelling-Williams t-test at a 5% level. Standard error on regression coefficient is 0.02 in all cases
