Craig Yencho, a renowned sweet potato and potato researcher with North Carolina State University, has been selected as a 2023 fellow in the National Academy of Inventors. NAI fellows are honored for the societal and economic impact of their inventions. 

Yencho is the co-recipient of more than 55 U.S. and international plant patents. He has participated in the development and release of 45 sweet potato and potato varieties. 

Yencho is a William Neal Reynolds Distinguished Professor at NC State and faculty member in the College of Agriculture and Life Sciences’ Department of Horticultural Science. He serves as program leader for the university’s sweet potato and potato breeding and genetics programs.

For more than 20 years, Yencho has conducted research in Africa, leading multinational teams focused on improving sweet potatoes in Sub-Saharan Africa and developing new genomic tools that African sweet potato breeders can use on the continent.

In 2005, Yencho and colleague Ken Pecota released the Covington sweet potato, a variety now grown in 90 percent of North Carolina sweet potato fields and on 20 percent of U.S. sweet potato acreage. Covington sweet potatoes have generated over $3.5 billion in revenue for North Carolina sweet potato growers. The crop is exported to Europe and used in a variety of products, including vodka. Yencho and Pecota received NC State’s 2021-22 Innovator of the Year award.

Yencho will receive a medal at the National Academy of Inventors annual meeting in Raleigh on June 18, 2024, when a senior official with the U.S. Patent and Trademark Office honors the 2023 class of fellows

He joins two previous inductees from the Department of Horticultural Science: Sylvia Blankenship (2018) and Thomas Ranney (2020). Other CALS inductees include Kenneth Swartzel (2019) and Rodolphe Barrangou (2019), both from the Department of Food Bioprocessing and Nutrition Sciences.

Since its inception in 2012, the NAI fellows program has grown to include 1,898 researchers and innovators, who hold over 63,000 U.S. patents and 13,000 licensed technologies.
