Our Project aims to develop breeding materials to increase rice production for Madagascar agro-ecological conditions, using available local resources. Therefore, breeding materials from crosses between previously identified donors and local Malagasy cultivars were performed, and their advanced generations are being evaluated in farmer’s fields of several rice producing areas of Madagascar. I, therefore, traveled to Madagascar to conduct the harvest and evaluation of those field experiments, which targets are to evaluate yield trials for elite breeding lines, and selection of best performing lines for breeding purpose. The trials were conducted under upland or lowland conditions. The harvest was performed according to their panicle maturity stage. Parameters evaluated in the field were: plant height, tiller number, and panicle number. Straw and panicle were brought to the laboratory to obtain their dry weight. In addition, individual representative breeding lines were selected for advance generation and seed multiplication in a warmer location (Majunga).
