| Research Abstract |
To develop the conservation strategy of endangered wild primroses, we tried to identify the adaptive genes by QTL analysis and the genome-wide gene analysis based on the expression genetic information. Several associated gene regions about hetero style which affected the continuation of the group were detected with high precision. We clarified that a bottle neck effect committed the process of domestication by a comparison between genetic diversity of wild primrose and cultivars. Using EST markers, genetic analysis about the adaptive characters including the budding date and the flowering time were performed for 7 populations from Hokkaido to Kanto region. We could detect a lot of loci about budding in conjunction with the adaptation of the primrose. The results of our study will contribute not only the development of the conservation strategy, but also will become the model which show how to use genome information for conservation strategy.
