  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. GBLUP-g/gp is the ratio of population accuracies for lines in VP from GBLUPg and GBLUPgp, where GBLUPg is GBLUP incorporating genotypes on lines in VP, and GBLUPgp is GBLUP incorporating genotypes and phenotypes on lines in VP. MGBLUP-g/gm, MGBLUP-gm/gmp and MGBLUP-g/gmp are similarly defined with “gm” denoting genotypes and metabolomics on focal lines, and “gmp” denoting genotypes, metabolomics and phenotypes on lines in VP
