Video: New Mexico State University researchers conduct field trials of South American potato, papa criolla

Woman in hat holding potato plantNew Mexico State University is collaborating with U.S. Department of Agriculture research geneticist Kathy Haynes to conduct field trials of the South American potato, papa criolla, that she has breed to grow in the United States. White-fleshed potatoes typically grown in the United States are low in carotenoids that act as antioxidants for healthy eyes. The most well-known carotenoid is beta-carotene found in carrots. The carotenoids in the South American papa criolla potatoes, which make the potato yellow-fleshed, are lutein and zeaxanthin, which help prevent age-related macular degeneration. At least one study has suggested that zeaxanthin also improves mental acuity in elderly people. “Yukon Gold, a yellow-flesh potato that consumers are familiar with, has these carotenoids,” Haynes said. “Comparatively, the papa criolla types have 10-20 times more lutein and zeaxanthin than Yukon Gold.” Watch YouTube video. More information will be presented at the New Mexico Sustainable Agriculture Conference Wednesday, Dec. 13. Also see this press release
