Ampelographical errors good and bad

It has recently emerged that some Australian vine growers have been growing Savagnin Blanc (Traminer), an obscure French variety from the Jura, rather than what they thought they had planted, the considerably sexier Spanish grape Albarino. Apparently, CSIRO was sent mis-labelled cuttings by the National Germplasm Collection of Spain, a mistake that was spotted only after DNA work. It’s all explained, with what I suspect is relish, in an article in the New Zealand Herald. ((The problem seems to have surfaced in the press back in April, but we missed it at the time.)) Just the latest in a long line of trans-Tasman wine spats.

For the Australian winegrowers that have planted the 150ha currently in production in the country, this discovery is a blow as while there’s demand for albarino, the profile of savagnin – which they must now label wines made from these vines – is considerably lower.

As the article points out, not all such errors in identification are bad news.

Over a decade ago in Chile, another case of confusion proved more fruitful when what the Chileans had previously considered merlot actually turned out to be carmenere. This “lost grape of Bordeaux” was virtually extinct until it was found alive and growing very well among the merlot in Chile. It was a situation that inadvertently preserved the variety and led to the New World wine-producing nation to embrace it as a real point of difference and claim it as its flagship variety.

DNA fingerprinting should put a stop to this, of course. But as there are “5000 wine grape varieties with over 20,000 different monikers,” at least according to the article, it may be a while until cases of vine mistaken identity are things of the past.

Press alerted as to importance of agrobiodiversity

USDA had a nice press release out yesterday about the importance of conserving crop diversity. The example used is the Russian wheat aphid threat to the United States back in 1986. But why do this just now? In preparation for the Third Session of the Governing Body of the International Treaty on Plant Genetic Resources for Food and Agriculture? But that’s two weeks away. Maybe for the International Day of Biodiversity? That’s still a week away, though. I don’t get it. I like it: the time is always right to bang on about plant genetic resources conservation. But I don’t get it.

Finnish genebank attacked

Something else to add to the long list of problems that can afflict field genebanks:

Hordes of moles have penetrated into the MTT Agrifood Research Finland plant gene bank in Laukaa during the winter.

A lot of damage was done to fruit tree saplings in particular. Fortunately, there is a back-up site, but not all material is safety duplicated. More protective measures are to be introduced. Also, there seems to be a lot of cryopreservation work going on at Laukaa, so maybe in time there will be an added level of protection. MTT Agrifood research have a nice pamphlet on Finnish agrobiodiversity and its conservation.

Wild fruit relatives threatened in Central Asia

Fauna & Flora International and Botanic Gardens Conservation International (BGCI) have published a Red List of Trees of Central Asia. This is part of the Global Trees Campaign.

The new report identifies 44 tree species in Kyrgyzstan, Kazakhstan, Uzbekistan, Turkmenistan and Tajikistan as globally threatened with extinction. Many of these species occur in the unique fruit and nut forests of Central Asia, an estimated 90% of which have been destroyed in the past 50 years.

One of the threatened fruit trees is the red-fleshed Malus niedzwetzkyana, from Kyrgyzstan.

Working with the Kyrgyz National Academy of Sciences, the Global Trees Campaign is identifying populations of this rare tree in Kyrgyzstan and taking measures to improve their conservation. With distinctive red-fleshed fruit, the Niedzwetzky apple is an excellent flagship for the conservation and sustainable management of this beleagured forest type.

The report is available online.
