Table 3 Weighted average (WA) Pearson’s correlation for validation V00 (prediction of new lines observed only in one year - leaving one year out at a time as testing set) for eight models (M1: environment + pedigree; M2: environment + pedigree + pedigree × environment; M3: environment + marker; M4: environment + marker + marker × environment; M5: environment + pedigree + marker; M6: environment + pedigree + marker + pedigree × environment + marker × environment; M7: environment + pedigree + marker + pedigree × marker; M8: environment + pedigree + marker + pedigree × marker + pedigree × marker × environment) for grain yield (GY), days to heading (DTH), days to maturity (DTM), plant height (PH), and lodging (LD) for a wheat breeding pipeline comprised of 35,403 lines observed in four periods/years (13-14, 14-15, 15-16 and 16-17). Lines were observed only once across all periods
