| Outline of Final Research Achievements |
For the first time in the world, a hybrid between edible asparagus and a native species of asparagus plant of Hamatamaboki has been shown to be resistant to stem blight disease. Although Hamatamaboki is an endemic species that grows only along the northern coast of Kyushu and has been recognized as a disease-resistant plant, field surveys in its native habitat have revealed that pathogenic fungi of the fungal genera were Phomopsis, Neopestalotiopsis, Fusarium and Botrytis. As a result, the pathogenic fungi of this plant described above were described.
In addition, we found that Trichoderma spp. were frequently established in the rhizosphere of this plant in the native habitat, and the rhizosphere establishment of this fungus made it possible to grow this plant in the commercial horticultural media.

| Academic Significance and Societal Importance of the Research Achievements |
研究成果の学術的・社会的意義は、現在、自生地の現地調査と被害個体の調査から、本植物の生息域の減少の一要因として、複数種の植物病原菌類による複合感染の現状を明らかにしたことにより、絶滅危惧種IAに指定されている本植物の希少種としての保護の必要性を学術的に証明したことにある。また、根圏微生物の定着による微生物コンソーシアムの環境維持によって、市販の園芸用培土でも生育が可能であるという学術的な発見は、本植物の繁殖技術や確立や希少種の保護対策、生態系や生物多様性の保全などにつながることからも社会的意義は高い。
