Bridging the genotype-phenotype gap in 3D

Struik, Paul C.


Three-dimensional architectural models have become important tools for studying physiological relationships between form and function in crop stands. Incorporating genetic variation in architectural traits would allow the use of such models for model-based, marker-assisted breeding. Perez et al. (pages 4507–4521 in this issue) applied mixed-effect models on allometric relationships to account for genetic variability in the 3D architecture of oil palm, demonstrating that there is a trade-off between model accuracy and ease of defining parameters for the 3D reconstruction.
