The Japan International Research Center for Agricultural Sciences (JIRCAS) is now accepting applications for fixed-term employment of young researchers.

In order to facilitate further advancement in research activities that meet global challenges, JIRCAS is offering fixed-term employment aimed at nurturing excellent and highly motivated young researchers in pursuing research in the field of agriculture, forestry and fisheries.

The employment contract is subject to renewal after an evaluation of the performance and achievements of the researcher to be carried out 11 months before the end of the term. A fixed-term researcher who successfully passes the evaluation will be employed continuously as a regular researcher.

A fixed-term researcher may take maternity leave, childcare leave, or nursing leave during the term, and may apply for extension of the term to cover the period for leave of absence.

Overview of research activities

Plant phenotyping is important in breeding and cultivation. Recent advances in genomics and information technologies facilitate the development of novel phenotyping platforms for more efficient and accurate evaluation of physiological, morphological and ecological interactions in plant growth. In addition, the development of continuous and non-destructive phenotyping technologies enables us to conduct effective crop management and yield prediction in model crops. So far, JIRCAS has introduced germplasms of rice, sugarcane, tropical fruits etc. and has developed breeding materials in collaboration with counterpart research organizations in developing countries. To utilize these germplasms, morphological and physiological characterization of these germplasm must be carried out using new phenotyping methodologies to identify and clarify the genetic diversity and factors of agronomic traits by new methodologies in phenotyping. The results will be linked to the development of new breeding materials, crop management and/or fed back to plant control. Furthermore, it is also necessary to disseminate the information for application in the breeding programs and efficient crop management of developing countries.

In order to maximize the utilization of our germplasm collection and to facilitate the breeding of new crops in developing countries, we are looking for a researcher who can pursue research in developing (1) novel efficient phenotyping methods using machine learning, and (2) applications of simplified methods of plant diagnosis using smartphones for implementation in developing countries. The candidate researcher will be based at the Tropical Agriculture Research Front (Ishigaki) and is expected to engage actively in the promotion of domestic and international collaborative research from a global perspective in the future.

Research topics

  • Development of continuous and non-destructive phenotyping methodologies for tomato, strawberry and other crops in environmentally controlled greenhouse.
  • Development of non-destructive and efficient phenotyping methodologies in the field for agronomic traits of rice or sugarcane germplasm
  • Development of measurement methods of floral traits of tropical fruit germplasm by 3D-structural analysis
