Development of resilient crops and production technologies
The frequent occurrence of extreme weather events due to global climate change, environmental degradation caused by rapid population growth, and crop production in marginal areas are destabilizing crop production and threatening global food and nutrition security. Global warming and rapid population growth are further aggravating the global-scale issues, making it difficult to respond to them with conventional breeding strategies. In anticipation of the increasing and accelerating impacts of climate change, it is highly desirable to accelerate the resolution of global-scale issues through new technologies that integrate synthetic bioengineering and big data.
We will pave the way for the production of resilience-enhanced crops by developing the necessary technologies to create or produce resilient crops that are resistant to various external disturbances, such as poor environments, mainly targeting major crops such as rice and soybean, and the orphan crop quinoa.
- Development of technology for resilience enhancement production of high nutrient crops using genetic resources
- Development of basic technologies for resilience-enhanced crop design
- Development of breeding infrastructure utilizing untapped genetic and physiological mechanisms related to improved resource use efficiency
- Development of disease control technology with low environmental impact by utilizing disease resistance

JIRCAS participated in the international cooperation event "Global Festa Japan 2023" and introduced its research activities and international cooperation in Bolivia, South America, on quinoa, a highly nutritious crop that grows in harsh environments.
A group of 20 second-year students and two teachers from Fukuoka Prefectural Yahata High School visited JIRCAS on August 2, 2023 through the “Tsukuba Science Tour” program.
On August 2 (Wed) and 3 (Thu), 2023, the JIRCAS event entitled “Discovering the Wonders of Superfood Quinoa” was held at the Tsukuba Business-Academia Cooperation Support Center exhibition corner.
Pick UpAsian soybean rust is a serious problem in soybean production in tropical and subtropical regions. This disease is also a problem in Bangladesh along with the expansion of domestic production. In this study, we investigated the virulence of the Asian soybean rust against known resistance genes in order to control this disease through the introduction of resistant varieties. The results showed that while the virulence of the pathogenic samples in 2016 was weak and many of the known resistance genes were effective, the virulence of 2018 and 2019 samples changed strongly. They included a strongly virulent rust samples for which seven known resistance genes were completely ineffective. While the introduction of resistant varieties is effective from a cost and environmental impact perspective, the development of resistant varieties using gene-pyramiding to deal with highly virulent rusts is needed to achieve a stable effect of control.
