Description
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 under untested environments will be developed through the integration of genomic selection prediction models and eco-physiological crop models. To develop the model, we conducted re-sequencing of six representative rice cultivars to determine polymorphisms in genes strongly related to the environmental response (e.g., heading date genes), and measured phenotypes of the cultivars throughout their growth process in early and late cultivation seasons. These data will be analyzed with phenotypes and genome-wide marker genotypes of 110 Japanese rice cultivars and recombinant inbred lines derived from the cross between two Japanese cultivars.
