Research Activities
Rice is cultivated all around the world and shows numerous morphological and physiological differences in the form of phenotypic variations. Some of these variations have been used as genetic resources to improve rice plants so that they better satisfy human needs. Phenotypic variations are considered to be genetically controlled by the collective function of a large number of genes on rice genomes. However, the genetic bases and biological functions of most of them are still unknown, which has prevented us from wider practical application of rice germplasms. We exploit useful phenotypic variations from a wide range of rice germplasms and clarify the genes involved with biological functions by aid of recent advances in genome information and technology. Also, we try to develop new breeding materials and propose more effective breeding methodologies.

Future Plan
Through our current research activities, we aim to establish a consecutive road map from the genome information of germplasms to actual crop breeding.
