Description
Latifa Greche, Nicolas Virlet, and Malcolm J Hawkesford present a 2026 method for measuring wheat heads in 3D. The wheat head, or spike, holds the grains, and its shape affects yield. Hand measuring is slow and error-prone, which blocks large breeding studies. The team built a scanning pipeline that rebuilds each spike as a sharp 3D cloud of points.
Software lines the scans up and extracts length, volume, and cross-section shapes on its own. New measures capture zones of failed spikelets and the branching of spike parts. The 3D traits matched classic measures such as spike and seed weight. The method separated 12 wheat types into clear shape groups, from long to compact. The authors offer it as a fast, harmless tool for breeders.
