Development of an integrated modeling method for designing new cultivars with high performance

Global climate change and local abnormal weather are causing heavy damage to agricultural production. In this research project, we will develop a modeling method for designing genomic ideotypes of rice and a model-based simulation system. A model predicting phenotypic responses of untested genotypes will be developed through the integration of genomic selection prediction models and novel view points describing eco-physiological traits. To develop the model, we conducted re-sequencing of rice cultivars to determine polymorphisms in genes strongly related to the environmental response (e.g., grain filling ratio), and measured phenotypes of the cultivars.
