Planting a barrier to block UG99 wheat rust

An article in the November issue of Agricultural Research magazine, house organ of the US Department of Agriculture, warns: “World Wheat Supply Threatened!” complete with exclamation point. Well, yes, as we have indeed pointed out before. However, the article’s subtitle explains: “Luckily, research is under way to defend this grain of life.”

Phew! They had me worried.

Hidden in the write-up, which is to-the-point and interesting, is what struck me as a pretty off-the-wall suggestion. US scientists plan to focus resistant varieties (if and when they are developed) in southern states such as Texas, Georgia and Louisiana. The spores of UG99 can overwinter in the warm climates of the South, so the hope is that by preventing the disease getting a hold there, they can prevent it spreading to the rest of the country. Intriguing idea, but I wonder whether it really stands a chance.

There’s more in the article, on the resistance genes that might be inserted into US wheats and on the vital role of properly trained people in the field, who spotted UG99 early on and were able to sound the alarm.

More on EU Conservation Varieties

I didn’t realize it at the time, but that meeting in Vicenza was part of an EU-funded project called Farm Seed Opportunities. So the EU funds a project to explore ways of overcoming the strict rules for the marketing of seeds — which the EU sets. This isn’t the only example of a lack of joined up thinking; there are the subsidies to the tobacco farmers ranged against the budget for no-smoking campaigns, and probably others too. But I digress.

The Directive on Conservation Varieties is currently in its 11th draft, and is due to be discussed again by the EU today, 9 November, as Item 5 on the agenda of the Standing Committee on Seeds and Propagating Material for Agriculture, Horticulture and Forestry, an element of the Health and Consumer Protection Directorate General. I think one intention of the Vicenza meeting was to sound out Italian players with a view to making their views known in today’s discussions.

So what are those views? I’m afraid I don’t know. There seems to be a general desire to see farmers and others allowed to market seeds of varieties, balanced by a worry that any legislation may offer big seed companies a low-cost route to marketing their varieties. Some say the maximum amounts of seed prescribed in the draft are too low, which seems to play into the hands of the big seed companies. Is the answer a tighter definition of “conservation” and “amateur” varieties, one that big players would not be able to meet? Or is the answer to reduce quantities still further, so that there is no incentive for the big players to exploit these directives?

Noble farmers experimenting with and exchanging their cultural and agricultural inheritance form a crucial part of the narrative surrounding many objections to Europe’s existing seed laws. If that’s true, then small quantities should be no obstacle. Indeed, they should promote the kind of experimentation and adaptation that lie at the heart of farmer conservation, as they bulk up the seed to make commercial use worthwhile.

Another aspect of the argument around these ideas is that somehow there is a clear and present need to regulate the market for all kinds of seed. Why? I believe that ordinary consumer-protection laws are definitely sufficient as far as seed quality (germination, health) are concerned, and that they could probably cope with questions of identity as well. And for small quantities, where the downside — for incomes and food production alike — is more or less trivial, that ought to be enough.

I’ll be interesting to see how today’s discussions go; in the meantime, civil disobedience seems to be the only alternative.

While we’re on the subject, BBC Radio 4 is airing a two part series called Save our Seeds with the estimable Jonathon Porritt doing his thing. The first programme, on Wednesday 7 November, “explores the ancient origins of our agricultural biodiversity and how scientists are working to gather and secure as many plant varieties as possible.” Part 2, on Wednesday 14 November, “examines the controversial fallout of the Green Revolution and the inherent danger of single variety crops.” Ho hum.

A peach of a result for diversity and nutrition

Nobody eats a peach because they fancy a shot of carotenoids. Or do they? If so, they’d be better off choosing a yellow-fleshed variety. Scientists at Texas A&M University have examined the nutrients in 22 peach and 53 plum varieties and — Lo! — there are significant differences among them. 1

The differences in the genotype’s specific antioxidant capacity indicated that the phenolic profiles in the genotypes differ significantly. In general, the wide range of phytochemical content and antioxidant activity (AOA) found indicate that the genetic variability present can be used to develop cultivars with enhanced health benefits.

Meantime, if you can’t wait for new varieties, just pick red fleshed peaches for antioxidant activity and yellow ones for a vitamin A boost. Seriously, this is another little package of data on varietal differences, and as such we welcome it.

Melaku Worede says Africa must protect plant genetic resources

“I get very worried when new technologies are developed and oriented towards exploiting the African farmers. It’s wrong for big agro-multinationals to force African farmers to use new seed varieties which will disempower them and lead to dependency when local varieties suitable to local conditions can be enhanced.

“I get very concerned when European plant genetic researchers use African farmers as guinea pigs. What they cannot do in Europe they do it here in Africa,” said Dr. Melaku, renowned for his pioneering work in plant genetic research and his role in restoring Ethiopia’s food security and plant resources.

This is from a long interview with Melaku Worede in Black Star News. I wonder how accurate the interview is. Doesn’t sound much like the champion of plant genetic resources of old.
