| Outline of Final Research Achievements |
Given the Convension of Biodiversity (CBD) held in 2010, conservation of bio-and genetic diversity has been encounraged. In this research, we showed how the genetic resources have been changed in terms of diversity. We calcuated the phenotype diversity as coefficient of variation and data richness. Until 1990s, coefficient of variation has been slightly increasing, while it is rather stable since then. This shift is reflected the decreasing number of new variety introduced to the Japanese genebank, and this decreasing number can be reasonably reasoned as the effect of CBD.
On the other hand, data richness which indicate the number of available data per variety has been in increasing trend. Because of the decreasing number of variety introduction, reseachers have shifted from new introduction to increasing the utlization of pooled variety at hand. Given the tightened situation over the genetic resource use, it is important to utilize the already-introduced resources.
