Dr. TAKADA Kanako, a research fellow in the Crop, Livestock and Environment Division, received the 2022 Promotional Award for Achievement in Tropical Agriculture from the Japanese Society for Tropical Agriculture (JSTA) for her research on biological nitrogen fixation and symbiosis of nitrogen-fixing bacteria in tropical yams.
The Guinea yam genetic resources collection developed by JIRCAS in collaboration with the International Institute of Tropical Agriculture and the Iwate Biotechnology Research Center, and to be used in improving the efficiency of breeding and cultivation of Guinea yam, was featured as a science news on the website of the Crop Science Society of America.

541. Elucidating the Relationship Between Flowering Sex and Yield of White Guinea Yam― Towards the Development of Efficient Cultivation Methods―White Guinea yam is widely grown in the West African coastal region (Guinea Savanna) and is an important crop that supports food supply and demand in this region. However, the labor-intensive cultivation of white Guinea yams is a major burden on farmers. In collaboration with the International Institute of Tropical Agriculture (IITA) in Nigeria, JIRCAS has now clarified the effect of flowering sex on tuber yield of white Guinea yam, which has not been well understood for a long time. This achievement reveals the possibility of yield improvement through flowering control in yams.
