Fig. 6: Cross validation schemes used for assessing predictive ability.

CV1 and CV2 schemes used for single trait multi-environment (STME) (a, b) and multi-trait multi-environment (MTME) (c, d) prediction models. Black rectangular cells indicate presence of phenotypic data and white rectangular cells indicates absence/masking of phenotypic data (testing dataset). Each rectangular cell represents line and environment combination in STME prediction models and line, environment and trait combination in MTME prediction models.
