Interpretive Summary: Future agriculture faces a challenge of population growth and climate change and thus increases the demand for more food to feed the world. Plant breeding and biotechnology have introduced innovative approaches to meet the food demand and achieve sustainable crop productions. High throughput phenotyping (HTP) is critical to facilitate the data pipeline in breeding. Many institutes have initiated HTP programs and their expectations are high but with a limited success in efficiency and scalability. This paper discusses the overview of current HTP research activities and provides a roadmap and strategies on HTP research, including system components and image analytics. The paper also addresses the importance of HTP in ag industry, factors to consider in each component, and the scale-up of HTP-related processes.

Technical Abstract: Population growth and climate uncertainty increase the demand for more food to feed the world. Finding a new variety and discovering novel genetic traits that confer stress tolerance will be a game changer in future crop production for sustainable agriculture. Developing and implementing high throughput phenotyping (HTP) technologies and skills become increasingly important to those involved with applying genomics in breeding and biotechnology research. Many institutes and private companies are initiating HTP programs to improve the quality and speed of plant breeding and biotechnology. Breeders and plant scientists need to secure solid data pipelines of phenotypes throughout years-long breeding programs, but they lack an engineering background on sensors, image processing, data management, and cloud-running architecture. Purpose: There are a series of components and steps that must be considered for HTP programs to meet their needs and goals. Those components include sensors, platforms, analytics, and data management. The aim of this paper is to address key information of what plant breeding is, why HTP is important, and how the HTP system is designed. Review: The paper describes background of plant science to engineering to enlighten the need of HTP and provides a review of the current HTP systems and future strategies. Discussion includes specifics of each HTP component to consider and a roadmap to HTP for plant breeding throughout genetics, phenotypic metrics, algorithm development, data standardization, and scaleup.
