| Outline of Final Research Achievements |
In order to establish a new theoretical framework of breeding research, we worked on the integration of conventional pedigree information and construction of a theoretical framework for finding further breeding targets. Pedigree information of the Japanese malting barley varieties more than 1,500 varieties, which has a breeding history more than a century, and the track record of joint breed comparison tests conducted by the public and private sectors during 50 years were collected. Moreover, GRAS-Di analysis was performed for ca. 200 representative lines based on the pedigree data, and the implementation base of genome-wide association analysis was established.
The issues addressed in this research contribute to the establishment of a systematic theoretical basis that provides an overview of the breeding history, and the development of a knowledge base that promotes improving the varieties in multiple ways.
