Breadfruit Institute



Established in 2003, the Breadfruit Institute is a part of the Science and Conservation department of the National Tropical Botanical Garden. The institute’s mission is to promote the conservation, study, and use of breadfruit for food and reforestation. Breadfruit is an indigenous, traditional crop that continues to serve as a critical food, economic, and ecological resource for its traditional countries of origin in the Pacific, as well as in tropical communities where it is grown globally. 

The Institute is a global leader in efforts to conserve and use breadfruit diversity and knowledge; with the purpose of supporting regenerative agriculture, food security, and economic development in the tropics. The Institute curates, studies, and conserves the world’s largest germplasm breadfruit—150 varieties—at NTBG’s Kahanu Garden on Maui and at McBryde Garden on Kauai.

A small farmer, born and raised in Hawai`i, Noel attended the University of Hawai`i in Hilo where she earned a B.S. in Horticulture with specialization in Tropical Plant Science and Agroecology, as well as Plant Tissue Culture certification. In addition to her responsibilities as the institute’s Coordinator, Noel is currently pursuing a PhD degree from the University of Copenhagen, Denmark, focusing on improvement of conservation, curation, and management of collections of heritage crops and their wild relatives within botanical gardens -specifically Artocarpus.

Mariella Mladineo, Agroforestry Technician

Mariella earned a B.S. in Sustainable Agriculture & Food Systems with a focus on ecology and production at the University of California, Davis. Her education gave her insight into the complications and rewards of pursuing environmental, economic, and social sustainability in food production. Mariella thoughtfully cultivates the Regenerative Organic Breadfruit Agroforestry demonstration at McBryde Garden using her knowledge of sustainable practices, assists in breadfruit-related research projects, and maintains an excitement for inclusivity and community opportunities at the Breadfruit Institute.
