Millennial beans

beans

Nice enough beans, ((And thanks to Bisse for letting me use her flickr pic.)) but is the story circulating about them really true?

The story of Anasazi beans varies, depending on who is telling it. In popular mythology, the beans were uncovered by an anthropologist, who discovered a 1,500 year old tightly sealed jar of the beans at a dig in New Mexico. Some of the beans germinated, and the new variety of bean entered cultivation again.

I tried to track the story down, and the closest I got to paydirt, I think, was a passage in Beans: A History by Ken Albala. But even that is pretty vague really. Archaeologists from UCLA somewhere in the midwest in the 1980s, or maybe 1950s, uncover a clay pot sealed with pine tar which they carbon date to 500 BCE. Some of the beans sprout and an intrepid businessman markets them. Yeah, right. To go back to the source of the previous quote:

Since most botanists agree that most beans are unable to germinate after approximately 50 years, it is more probable that the beans remained in constant cultivation in the Southwest, probably in Native American gardens, and that they were picked up by companies looking for new “boutique beans.”

There are plenty of companies marketing Anasazi beans now. But actually it is not impossible for legume seeds to keep their viability for more than 50 years — that’s what genebanks are for. And the dry, relatively cool conditions of an Arizona cave might just be good enough to ensure the survival of a few beans for centuries.

Turkey offers D-8 agrobiodiversity conservation help

There’s a bit of follow-up on the news from a few weeks back that Turkey was planning to build another genebank. At a meeting of the D-8 countries (Malaysia, Indonesia, Bangladesh, Pakistan, Iran, Turkey, Egypt and Nigeria), Turkey’s Agriculture and Rural Affairs Minister Mehmet Mehdi Eker proposed that “the seed bank to be established within D8 countries be housed in Turkey.” So it will be a sort of regional backup facility? Hard to say. The plot thickens.

Using wild rice to fight pests

Well, maybe. The article in The Monitor is a bit confused. Yes, there are wild rices in Uganda. I know because I was (marginally) involved in the 1997 Sida-IRRI project which collected wild Oryza in Eastern and Southern Africa. The material has been conserved since then in the National Genetic Plant Resources Centre for Crops in Entebbe, and has now been evaluated — successfully, it would seem — for resistance to Yellow Mottle Virus. Which is great. But the crossing with cultivated rice has not started in Uganda, I don’t think. The crosses that are alluded to in the article seem rather to have been between Asian rice and cultivated African rice (Oryza glaberrima), presumably aiming to replicate the success of Nerica in West Africa. Anyway, good luck to Drs John Mulumba Wasswa and Jimmy Lamo with the breeding programme.

India’s National Biodiversity Action Plan released

Yes, it’s out. India’s NBAP is online. Unfortunately, the pdf cannot be searched, for some reason, but a quick skim reveals that it does include significant consideration of agricultural biodiversity issues. For example, there’s a discussion of the role of the National Bureau of Plant Genetic Resources (NBPGR) in ex situ conservation of crop genetic resources.

Here’s the money quote, on page 52:

Traditional Indian farming systems are characterized by remarkable diversity owing largely to wide spectrum of agro-climatic situations and indigenous cultivars and native breeds adapted to specific local conditions. Notable efforts to collect crop diversity and documenting of livestock breeds notwithstanding, there is a need for on-farm conservation providing appropriate incentives. Ex situ conservation is expected to provide a strong backup to the efforts to facilitate access and meet unforeseen natural calamities. While there is an increasing coherence of policies and programmes on in situ, on farm and ex situ conservation, there is need to further strengthen these efforts.

The recommendations follow on pages 59-60. With regard to on-farm conservation, they are:

  • Identify hotspots of agro-biodiversity under different agro-ecozones and cropping systems and promote on-farm conservation.
  • Provide economically feasible and socially acceptable incentives such as value addition and direct market access in the face of replacement by other economically remunerative cultivars.
  • Develop appropriate models for on-farm conservation of livestock herds maintained by different institutions and local communities.
  • Develop mutually supportive linkages between in situ, on-farm and ex situ conservation programmes.

And, on ex situ conservation:

  • Promote ex situ conservation of rare, endangered, endemic and insufficiently known floristic and faunal components of natural habitats, through appropriate institutionalization and human resource capacity building. For example, pay immediate attention to conservation and multiplication of rare, endangered and endemic tree species through institutions such as Institute of Forest Genetics and Tree Breeding.
  • Focus on conservation of genetic diversity (in situ, ex situ, in vitro) of
    cultivated plants, domesticated animals and their wild relatives to support breeding programmes.
  • Strengthen national ex situ conservation system for crop and livestock diversity, including poultry, linking national gene banks, clonal repositories and field collections maintained by different research centres and universities.
  • Develop cost effective and situation specific technologies for medium and long term storage of seed samples collected by different institutions and organizations.
  • Undertake DNA profiling for assessment of genetic diversity in rare, endangered and endemic species to assist in developing their conservation programmes.
  • Develop a unified national database covering all ex situ conservation sites.
  • Consolidate, augment and strengthen the network of zoos, aquaria, etc., for ex situ conservation.
  • Develop networking of botanic gardens and consider establishing a ‘Central Authority for Botanic Gardens’ to secure their better management on the lines of Central Zoo Authority.
  • Provide for training of personnel and mobilize financial resources to strengthen captive breeding projects for endangered species of wild animals.
  • Strengthen basic research on reproduction biology of rare, endangered and endemic species to support reintroduction programmes.
  • Encourage cultivation of plants of economic value presently gathered from their natural populations to prevent their decline.
  • Promote inter-sectoral linkages and synergies to develop and realize full economic potential of ex situ conserved materials in crop and livestock improvement programmes.

Lots of sensible stuff, and it’s good to see agrobiodiversity in there at all. I was particularly interested in the recommendation to establish a national database bringing together all genebanks. Let’s see what happens, maybe it’s a small step out of genebank database hell. No mention of the International Treaty on Plant Genetic Resources for Food and Agriculture, though.

LATER: Yes, indeed, the ITPGRFA is mentioned on p. 90. Thanks, Eliseu. Sorry about that. Still trying to work out why I can’t search the pdf… Ah, can’t search online, but can if I download it first.

LATER STILL: Forgot to mention that there are also a number of references to crop wild relatives, check out Table 4, for example.
