Outline of Final Research Achievements |
The earliness (or lateness) of heading is a major factor responsible for environmental response in rice. In this study, we worked on the modeling of the pattern of environmental response in heading date and yield related traits, which are influenced by the heading date. For the earliness (or lateness) of heading, we successfully developed the model predicting the heading date of untested varieties/lines based on the genotypes of DNA polymorphisms in heading date related genes and the temperature and day length of cultivation environments, by combining a crop model and a genomic prediction model. For the experiment using recombinant inbred lines, we developed a model predicting biomass by modeling the relationship between environmental conditions and the phenotypes of morphological traits that were measured in various growth stages.
