IRRI Concludes Hands-On Training Course on Rice Root Phenotyping for Global Researchers

Los Baños, Laguna, Philippines — The International Rice Research Institute (IRRI), through IRRI Education, successfully concluded the Training Course on Rice Root Phenotyping held from 20–24 April 2026 at the MS Swaminathan Building, IRRI Headquarters in Los Baños, Laguna. 

The five-day course brought together nine graduate students, researchers, and academic professionals from the Philippines, Taiwan, Kenya, Tanzania, and the United Kingdom. Participants represented diverse fields including agronomy, crop physiology, plant pathology, genetics, biology, horticulture, and plant breeding. 

The training aimed to strengthen participants’ technical competencies in rice root phenotyping through lectures, demonstrations, and immersive field and laboratory sessions focused on standardized methods for studying rice roots. 

Building Knowledge on Rice Root Research

The course opened with welcome remarks from Dr. Anilyn Maningas, Head of IRRI Education, followed by an opening message from the resource persons, Dr. Amelia Henry of CIRAD – French Agricultural Research Centre for International Development and Dr. Juan de la Cruz Jiménez Serna from the University of Copenhagen. 

Throughout the week, participants learned how to characterize soil-grown rice roots from both field and greenhouse experiments, apply sampling and analytical techniques for assessing root traits, and interpret root phenotyping data to support rice breeding and crop improvement efforts. 

Lecture sessions covered rice root research and its role in developing stress-tolerant rice varieties, as well as physiological adaptations of rice under flooded conditions. 

On the third day, Dr. Juan de la Cruz Jiménez Serna from the University of Copenhagen facilitated lectures and practical sessions on rice adaptations to flooded soils, root respiration, root porosity, apoplastic barriers, and radial oxygen loss. 

Learning Beyond the Classroom 

A key highlight of the training was its highly practical and hands-on design. 

Rather than limiting learning to classroom discussions, participants conducted activities in rice fields, greenhouses, and laboratories. These included soil coring, crown root sampling, root washing, root scanning, crown root counting, greenhouse lysimeter setup, hydraulic conductance measurements, root sectioning, anatomical analysis, and root hair scoring. 

Field activities were conducted at Field D24, where participants experienced firsthand the technical demands of root phenotyping under actual field conditions. 

Participants expressed appreciation for the strong emphasis on experiential learning. 

“This course is one of the best courses I registered [for]. More on hands-on practice than just PowerPoint presentations.” 

Another participant reflected on the intensity and memorable nature of the activities, sharing: 

“It’s definitely an experience that is unforgettable, the skills, the people and the heat.” 

Several participants also noted a deeper appreciation for the work involved in root research after observing IRRI staff and technicians in action. 

“Root washing is the biggest impression on me. The way IRRI technician has collected the sample is so cautious. I have improvement to do in my own research techniques and sample collecting.” 

One participant added: 

“I have a lot more understanding and respect for all the IRRI staff who prepared the seeds and samples for us after seeing the staff and the facilities in person.” 

Mini Symposium and Advanced Techniques Workshop 

On the fourth and fifth days of the training, participants attended a mini symposium and advanced techniques workshop that expanded their exposure to emerging research and innovations in rice root science. 

The sessions featured presentations and discussions on climate resilience, rice stress physiology, crop improvement, plant genomics, and root adaptations under different environmental conditions. Through these knowledge-sharing sessions, participants gained broader insights into how root traits contribute to stress tolerance, productivity, and sustainability in rice systems. 

In addition to research presentations, participants were introduced to advanced analytical and imaging techniques used in root studies, including specialized methods for root visualization, anatomical analysis, and gene expression investigations. 

These sessions complemented the practical training by allowing participants to connect the field and laboratory methods they learned during the course with current scientific advancements and ongoing research applications. 

One participant highlighted the value of this broader learning experience, sharing: 

“The course on rice root phenotyping was very informative and practical. It improved my understanding of root traits, phenotyping methods, and their application in crop improvement. The hands-on sessions and expert guidance were especially valuable. I now feel more confident to apply these skills in my research.” 

Another participant noted that the symposium and workshop provided useful perspectives for future work: 

“I have really learned many new things in this training. Everything was new to me but resource persons have made it very easy and understandable. I will be able to utilize this knowledge in my future research.” 

The mini symposium and workshop served as valuable platforms for participants to engage with current research directions, emerging technologies, and interdisciplinary approaches shaping the future of rice science. 

Advancing Global Capacity in Rice Research 

Through the Training Course on Rice Root Phenotyping, IRRI continues to strengthen global research capacity by equipping scientists and researchers with practical skills and advanced knowledge in rice root science. 

By combining classroom instruction with fieldwork, laboratory training, expert mentorship, and cultural immersion, the course provided participants with a comprehensive learning experience that supports future innovations in rice breeding, crop resilience, and sustainable agriculture.
