Automated Sorghum Phenotyping and Trait Development Platform

TERRA Purdue
Program: 
ARPA-E Award: 
$6,662,287
Location: 
West Lafayette, IN
Project Term: 
08/24/2015 to 02/23/2019
Project Status: 
ACTIVE
Technical Categories: 
Critical Need: 

TERRA project teams will integrate the agriculture, information technology, and engineering communities to design and apply new tools to the development of improved varieties of energy sorghum, a crop used to produce biofuel. Producing the large amounts of biomass needed for biofuels to displace petroleum requires significant improvements to the productivity and efficiency of biofuel crops. The teams will enhance methods for crop phenotyping (identifying and measuring the physical characteristics of plants), which are currently time-intensive and imprecise. The new approaches will include automated methods for observing and recording characteristics of plants and advanced algorithms for analyzing data and predicting plant growth potential. These innovations will accelerate the annual yield gains of traditional plant breeding and support the discovery of new crop traits that improve water productivity and nutrient use efficiency.

Project Innovation + Advantages: 

Purdue University, along with IBM Research and international partners from the Commonwealth Scientific and Industrial Research Organisation (CSIRO, Australia) will utilize remote sensing platforms to collect data and develop models for automated phenotyping and predictive plant growth. The team will create a system that combines data streams from ground and airborne mobile platforms for high-throughput automated field phenotyping. The team's custom "phenomobile" will be a mobile, ground-based platform that will carry a sensor package capable of measuring numerous plant traits in a large number of research plots in a single day. In addition, the team will use unmanned aerial vehicles (UAVs) equipped with advanced sensors configured to optimize the collection of diverse phenotypic data and complement the data collected from the phenomobile. Advanced image and signal processing methods will be utilized to extract phenotypic information and develop predictive models for plant growth and development. IBM Research will contribute high-performance computing platforms and advanced machine learning approaches to associate these measurements with genomic information to identify genes controlling sorghum performance. International partners from CSIRO will lend their expertise in crop modelling and phenotyping to the effort.

Potential Impact: 

If successful, the Purdue team will create a phenotyping system that optimizes high-throughput sensing technologies for acquiring relevant data on sorghum phenotypes. Combined with their data analytics efforts, this work may drive future sorghum genetic improvement, resulting in improved energy-sorghum varieties.

Security: 

Improved biofuel crops could lead to increased production of domestic biofuels, reducing dependence on foreign sources of transportation fuels.

Environment: 

Increased use of biofuels could significantly reduce CO2 emissions from transportation, and improved varieties of biofuel crops could use less water and be more resistant to environmental stress.

Economy: 

Advanced crop breeding techniques could improve and lower the cost of developing high yielding and high quality crop hybrids for biofuels and other agricultural applications

Innovation Update: 

(As of May 2018)

Under its ARPA-E award, the team has developed ground-based and aerial vehicles equipped with advanced sensors that monitor traits throughout the growing season, such as plant height and leaf number. That data is combined with traditional measures of performance to create trait indices for high-throughput phenotyping. The team also developed machine learning algorithms that can estimate leaf count and plant height, among other traits, and it is combining these measurements with visualization tools to provide interactive analytical capabilities. Purdue is also working to identify genes and alleles that can be used to enhance bioenergy value of sorghum feedstock.

 

Purdue has received $200,000 in follow-on funding from the United Sorghum Checkoff to further develop their technology. In addition, they received $150,000 in follow-on funding from a major agricultural corporation to develop new phenotyping technologies for maize breeding and genetics. The project leads have also launched CROPi Analytics, a startup company that provides robust data processing software for remote sensing applications in agriculture.
