Breeding info

Getting the new issue of CropBiotech Update in my inbox today, and noticing at least a couple of crop improvement items I would like to blog about at some stage, prompted a reflection on sources of information on the use of agricultural biodiversity in breeding.

Produced by the International Service for the Acquisition of Agri-Biotech Applications (ISAAA), you can get CropBiotech Update delivered by email once a week or check out the website here (where you can subscribe to an RSS feed or sign up for the email alerts). FAO also has a news service in biotechnology, which you can check out here. You can sign up for monthly email alerts, but I couldn’t see any RSS feeds, unfortunately.

Somewhat broader than either of these, but with some overlap, is Plant Breeding News, sponsored by FAO and Cornell University. You can sign up to the email alerts, consult the archives and learn how to contribute here. BIO-IPR is an irregular listserver produced by GRAIN. It focuses on PGR policy issues, and you can find out more about it here.

Finally, I just wanted to mention an example of a national-level agricultural research newsletter which provides information on breeding programmes, DIDINET News from the National Agricultural Research Institute (NARI) in Papua New Guinea. DIDINET stands for “Didiman/Didimeri Network” or a network for scientists and other stakeholders in the agriculture sector. There must be lots of other examples of such national newsletters. I wonder if someone has compiled a list.

And of course I haven’t mentioned the various ways the CGIAR Centres disseminate information about crop breeding, such as this one, for example. But maybe Jeremy will say something about that. He knows more about it than I do.

British landraces

Maria Scholten has written to us with some interesting websites about British landraces. She says that as Brussels prepares a new directive on the conservation of agricultural landraces, it is important to have some idea about the landraces that still survive even in countries like the UK with a highly industrialized agriculture, and the efforts underway to conserve them.

  1. a sainfoin (Onobrychis viciifolia) landrace from the eighteenth century and one grown, tested and promoted by sainfoin enthusiast Robin Hill
  2. an English native red clover landrace marketed by a local British seed company
  3. a barley, probably introduced by the Vikings, being researched for marketing potential on Orkney
  4. a group of organic growers on Shetland working to maintain Shetland “aets” and bere barley, the historical cereals of Shetland

Thanks, Maria!

Olive oil spreads

There’s increasing recognition around the world that olive oil, as a key component of the so-called Mediterranean diet, is really good for you. The latest news is about its effect on ulcers. So obviously the traditional growing countries are trying to expand cultivation and production. But as this article points out, that’s not always so easy. Pity there’s nothing in the piece on varieties, though.

Batty

This story is not particularly agricultural, but I couldn’t resist it. Brazilian researchers extracted the essential oils from a Piper sp commonly eaten by bats and then smeared the stuff on plastic fruits, which they then distributed in areas of damaged rainforest. The bats were attracted to the fake fruits, though they wouldn’t normally fly in degraded forest. Why go to all this trouble? Because the bats spread lots of seeds via their faeces, and could thus be used to restore the vegetation.

Using biodiversity collections

Researchers have estimated rates of reproduction and survival for the marbled murrelet by “comparing the ratios of birds in different age groups using 170 specimens collected between 1892 and 1922 housed in the collections of the California Academy of Sciences and the UC Berkeley Museum of Vertebrate Zoology … with values predicted from comparison with other bird species, and with contemporary rates obtained from murrelets they captured at sea and from their mark-recapture studies.” The results suggested that birth rates were almost 10 times higher for this endangered seabird 100 years ago than they are today. Read all about it here. That’s a very creative use of a biodiversity collection to explain the recent decline in numbers of this species, and its conservation status. Has something similar been done with herbarium and/or plant genebank collections? I can’t think of any examples, but they must be out there…
