| Outline of Final Research Achievements |
The risk of genetic pollution of native plants by revegetation using commercial seeds imported from foreign countries was evaluated, mainly for Indigofera pseudotinctoria. Analysis of nuclear and chloroplast DNA revealed that individuals derived from Japanese populations and foreign commercial seeds were genetically different. Natural hybridization between Japanese and foreign individuals may occur because there was overlap in flowering times. Japanese populations showed geographical structure. In order to conserve the genetic diversity and differentiation of Japanese populations, not only the use of foreign commercial seeds, but also long-distance movement of seeds in Japan should be avoided.

本研究では、コマツナギなど緑化に利用されるマメ科植物を対象とし、国内自生個体と外国産種子の遺伝的な違いを明らかにするとともに、日本国内での遺伝的変異とその地理的分布を明らかにした。また、コマツナギは緑化に使用されている日本産種子が限られた採取地由来であることを示した。これらの結果から、コマツナギの遺伝的地域性を保全するためには、外国産種子の使用を避けるだけでなく、日本産種子の採取地にも注意すべきであることから、日本国内での種苗移動ガイドラインを示した。
