成果の概要

In Madagascar, a series of field experiments are under way, managed together with our local research partners LRI and FOFIFA. Upland breeding trials with segregating lines grown under zero-input conditions were phenotyped and within most promising F4 lines single plant selections were made. In the lowland ecosystem, we had transplanted two agronomical experiments on nutrient efficiency and nursery management, as well as a breeding trial with Pup1 introgression lines. These were phenotyped for biomass and heading and single plant selections were made. Finally, an association panel of 360 rice accessions imported from IRRI, Philippines, was evaluated at three field sites ranging from medium (900m) to high (1290m) elevation. In all experiments, lines or accessions performing much better than local checks were identified.
At IRRI, I participated in the planning workshop for the RICE CRP in the role of JIRCAS focal person for flagship program 5 (FP5), which includes all pre-breeding and breeding activities. We defined activities for 2017, including specific quantifiable outputs and outcomes. In addition, the general strategy for communication, open access data management, capacity building and of gender-related activities of the FP5 was discussed and defined in a document.
