Field phenotyping research sites
Maricopa Agricultural Center (MAC), Arizona
The Maricopa field site is located at the the University of Arizona Maricopa Agricultural Center and USDA Arid Land Research Station in Maricopa, Arizona. At this site, we have deployed the following phenotyping platforms.
The Lemnatec Scanalyzer Field System is the largest field crop analytics robot in the world. This high-throughput phenotyping field-scanning robot has a 30-ton steel gantry that autonomously moves along two 200-meter steel rails while continuously imaging the crops growing below it with a diverse array of cameras and sensors.

The PhenoTractor is fitted with a sensor frame that supports a real time kinematic (RTK) satellite navigation antenna, a sonar transducer, an infrared temperature (IRT) scanner, and three GreenSeeker crop sensing systems.
UAV data: weekly flights with RGB and multispectral cameras
Manually Collected Field Data - Data will are collected manually using standard field methods. These measurements are used to calibrate and validate phenotypes derived from sensor-collected data.
Controlled-environment phenotyping
Donald Danforth Plant Science Center, Missouri
The Bellwether Foundation Phenotyping Facility is a climate controlled 70 m2 growth house with a conveyor belt system for moving plants to and from fluorescence, color, and near infrared imaging cabinets. This automated, high-throughput platform allows repeated non-destructive time-series image capture and multi-parametric analysis of 1,140 plants in a single experiment.
Genomics
Genomic data includes whole-genome resequencing data from the HudsonAlpha Institute for Biotechnology, Alabama for 384 samples for accessions from the sorghum Bioenergy Association Panel (BAP) and genotyping-by-sequencing (GBS) data from Kansas State University for 768 samples from a population of sorghum recombinant inbred lines (RIL).
