Breadfruit Institute

The National Tropical Botanical Garden established the Breadfruit Institute in 2003 to promote the conservation, study, and use of breadfruit for food and reforestation. The Institute is a global leader in efforts to conserve and use breadfruit diversity to support regenerative agriculture, food security, and economic development in the tropics and serves as the international center for breadfruit research and information resources. The Institute manages, studies, and conserves the world’s largest repository of breadfruit diversity—150 varieties—at NTBG’s Kahanu Garden, Maui, and the McBryde Garden, Kauai.

The Institute is also engaged in a Global Hunger Initiative to respond to critical global food security issues and deforestation by expanding plantings of good quality breadfruit varieties in tropical regions. This work is central to our participation in the Alliance to End Hunger—a coalition of 90 corporations, non-profit organizations, universities, individuals, and religious groups working to end hunger domestically and internationally.
