Down to Earth

Undergraduates require access to authentic field environments to learn effectively.

Predictive ability overestimates the relative accuracy of phenomic prediction (PP) versus genomic prediction (GP) models. Colored dots correlate with different traits tested in each case study. (A) Differences between estimated PP and GP accuracies are plotted against their estimated predictive abilities. Points to the right of the line are where the accuracy of these PP models tends to be overestimated compared with GP models, even when the PP models are actually less accurate (lower right quadrant).

Do not directly compare cross-validation results between genomic and phenomic predictions
