Development of Optimized Phenomic Predictors for Efficient Plant Breeding Decisions Using Phenomic-Assisted Selection in Soybean

Figure 1

Cross-validation scenarios (CV1 and CV2) and preprocessing methods (Methods 1 and 2) used to assess phenomic prediction model performance. Method 1 and Method 2 differ in BLUP computation, while CV1 and 2 depict two plant breeding scenarios for prediction in multienvironment tests. These CV scenarios represent a combination of different preprocessing (to handle missing data) methods and prediction challenges native to plant breeding practices. In Method 1, for both CV scenarios, individual environment BLUPs are computed and subsequently used in model training and testing the model. In Method 2, combined environment BLUPs are computed and subsequently used in training the model, while individual environment BLUPs are used in testing the model.
