Genetic Dissection of Growth, Development, and Stress Response in Diverse Sorghum with High-Throughput Phenotyping.

Genetic variation of growth, development, and stress response in diverse crop germplasm is generally poorly understood. Due to technical contraints of manual phenotyping, most field-based quantitative trait studies have been based on a limited number of accessions and small number of time-points through the growing season. Here I will describe the efforts of the TERRA Reference Phenotyping Platform (TERRA-REF) team to develop and apply high-resolution and high-throughput phenotyping tools for biomass sorghum. We have been using field high-throughput phenotyping with unmanned aerial systems and large robotic platforms to dissect the genetic basis of growth, development, and stress response in diverse global sorghum accessions.
