Orange revolution

Sweetpotatoes come in different colors and tastes (and sizes). The “yams” eaten in the United States are sweet and have orange and moist flesh. The staple of parts of Africa and the Pacific (and pig feed in China), is typically white-fleshed and not very sweet nor moist (notwithstanding variations like this purple variety.)

Anyway, the orange fleshed sweetpotato is stacked with beta-carotene, the stuff you need to eat for your body to make vitamin A. Many poor people have vitamin A deficiencies, which leads to stunted growth and blindness. So why don’t the poor sweetpotato eaters eat orange fleshed varieties? In part because they simply do not have them, or know about their health benefits. In part because they do not grow well in Africa (decimated by pests and diseases). And also because they do not taste right: too sweet for a staple.

The International Potato Center and partners have been trying to fix all that. Now they have made a nice video about getting orange-fleshed sweetpotatoes into the food-chain in Mozambique. The orange revolution:

I wonder if they also promote mixing more sweetpotato leaves into the diet — even of white fleshed varieties. The leaves are a very good source of micro-nutrients, including beta-carotene! More fodder for the biofortification discussion.

Seed exchange is evil

That’s not my view 1 but it seems to be what a commenter called Cassandra is saying.

If I could bring myself to be an “evil” person I would offer tons of my “HOMEGROWN” seeds to them and even ship them for free. That way I could get even with all the idiots that are happily transporting their “noxious” weed seeds along with their lovely and so prized Pansy seeds.

It’s time for the United States Dept of Agriculture to step up to the bat and start fining these idiots that are polluting the earth with weeds, among other things.

How about the lady that bought four trees off of a seller on that four “****” letter internet auction site, lovely trees they were. Nice full rootball with plenty of dirt still attached. Little did she know that she was also buying an entire family of “Fire Ants” . Have you ever tried to rid your property of “Fire Ants”?

Those are indeed shocking examples of bad consequences of ignorant seed and plant exchange. Myself, I’m not too sure how you would miss a fire ant nest in a rootball, but then almost all the trees I’ve planted have been bare-rooted dormant specimens. As for weeds among the seeds, again, I tend to sow all seeds in trays or pots, especially those I am experimenting with, maybe growing for the first time. That gives me a chance to select among the seedlings and to discard anything untoward. But I do that regardless of the source of the seeds; public, private, large, small — makes no difference to me.

Cassandra does have a point, but I also think that her ire is misplaced. The kind of people who would use seed exchanges to broaden their experience of agricultural biodiversity probably have a wee bit of indigenous knowledge. Is there any way to stop the spread of invasive weeds? I doubt it. All we can do is be vigilant. And careful.

So if your truly interested in some “AWESOME” Dahlia seeds, they have been in my family for generations please just ask me for them. Be prepared to have your request denied. I don’t even know you and care more about the wellness of your state and property than you do.

Actually, I’ve never grown a dahlia from seed, so yes, Cassandra, I would be interested. You can use the contact form to let me know how I can get in touch, as you forgot to leave an email.

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!
