マダガスカル現地圃場での播種

We have selected three different rice producing areas of Madagascar to evaluate our experimental lines, for the 2018-2019 main cropping season. Together with our project counterparts (C/Ps), we have sown a set of selected breeding lines to confirm their field performance, and to compare them against local varieties. Furthermore, we have selected genotypes from a genome-wide association studies (GWAS-2017-2018 season), and sown them to confirm the positive effect of putative QTLs related to grain yield. All experimental lines were sown on raised-bed soil at farmer fields. In addition, I have attended the 3rd TCC Project meeting to present and discuss our result, and to exchange ideas on subsequent plan. Furthermore, we have finalized the renovation design of the greenhouse allocated to our Project.

Starting the soil preparation for making soil beds. Bed soils are prepared manually

Preparation of elevated-bed soil under wet condition (with good source of water supply)

Sowing in bed soil under dry condition. Water is supplied manually using watering can

Seedling growth under dry condition. Insects and rats were attacking the young seedlings

Seedling growth under wet condition. Attack of insects was lesser than in dry condition
