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 harvested which included single plant selections within segregating F4 lines. Selections and harvests were also made at two lowland sites where IR64-Pup1 lines were grown. All harvested material was brought to FOFIFA for further processing and weighing. In the lowland ecosystem, we had transplanted two additional agronomical experiments on nutrient efficiency and nursery management, and these were also harvested to about 80%. 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 but because of rather late sowing and late maturity of several accessions, harvests have just begun and will stretch throughout May.
