Carlos Ochoa

Carlos Ochoa — legendary potato breeder, explorer and scholar — has passed away at an age of 79 in Lima, Peru.

Born in Cusco, Peru, Ochoa received degrees from the Universidad San Simon, Cochabamba, Bolivia and from the University of Minnesota, USA. For a long time Ochoa worked as a potato breeder. He combined Peruvian with European and American potatoes to produce new cultivars that are grown throughout Peru.

Ochoa was professor emeritus of the Universidad Nacional Agraria La Molina, Peru. In 1971, he joined the International Potato Center, where he worked on the systematics of Andean cultivated and wild potatoes. His long list of publications on this topic include hefty monographs on the potatoes of Bolivia and on the wild potatoes of Peru.

His last major published work (2006) is a book on the ethnobotany of Peru, co-authored with Donald Ugent.

Ochoa was a wild potato explorer par excellence. One third of the nearly 200 wild potato species were first described by him.

Carlos Ochoa received many international accolades, including Distinguished Economic Botanist, the William Brown award for Plant Genetic Resources, and, together with long time collaborator Alberto Salas, the Order of Merit of the Diplomatic Service of Peru.

Here is Ochoa’s own story about some of his early work, including his search for Chilean potatoes described by Darwin and his thoughts on potato varieties: “[they] are like children: you name them, and in turn, they give you a great deal of satisfaction”.

¡Muchas gracias, professor!

Cereal varieties screened for nutritional benefit

You may remember the obsession we developed here last summer about diversity among crop varieties in nutritional composition in general and glycemic index in particular:

Good measurements of characteristics such as GI for specific, named and recognizable varieties, whether the products of modern breeding or traditional farmer varieties, would be really valuable for lots of reasons, not least to add substance to claims that diversity of diet in and of itself is good for one.

Well, our prayers are being answered. Foodnavigator has a news item about the “Healthgrain diversity screen.” Researchers

grew, harvested and milled 150 wheat varieties used for bread making and 50 other grain varieties — oats, barley and rye — over a one-year period in Hungary. The grains originated worldwide…

They then measured “the components known to play a role in prevention of cardiovascular disease and type-2 diabetes,” including tocols, sterols, phenolic acids, folates, alkylresorcinols and fiber components.

Only one site and one year, and 150 are not that many compared to the tens of thousands of wheat landraces and varieties in the world’s genebanks, but you have to start somewhere, and “the Healthgrain diversity screen has generated the most extensive database currently available on bioactive components in wheat and other smallgrain cereals.” Should be a great breeding resource.
