  1. GBLUP  genomic best linear unbiased prediction; MGBLUP  metabolomic-genomic best linear unbiased prediction; LOLO  leave one line 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. For all traits, none of the differences between the two correlations are statistically significant using a Hotelling-Williams t-test at a 5% level. Standard error on regression coefficient is 0.01 in all cases
