Crowdsourcing crop diversity, and information

A couple of crowd-sourcing initiatives caught my eye.

First, the good people at the COUSIN project want to expand genebank collections of wild relatives of wheat, barley, lettuce, brassica, and peas in Europe. And they have a pretty good idea where the collecting needs to be done. Think you can help? Check out the call for proposals.

And from a bit further south comes a plea on LinkedIn from Chris Jones of the ILRI genebank. He needs help getting stuff out of the genebank rather than into it.

As part of the ‘low-methane forages’ project, funded by the Gates Foundation and the Bezos Earth Fund, we have been screening the methane emission intensity of a range of forage accessions, in vitro, from the International Livestock Research Institute (ILRI) genebank. The aim is to screen approximately 10% of the accessions held in our genebank and, to date, we have assessed 155 herbaceous legumes towards this goal, including several of our lablab accessions. From these, we have identified two accessions of interest. The methane emission intensity of accession #14447 was 27.7 ml/g total digestible dry matter (TDDM), 43% lower than the highest ten legumes measured so far, and methane emission intensity of accession #14458 was 33.8 ml/g TDDM, 30% lower. So, assuming that similar differences in methane emission intensity are realised in vivo (and that is no guarantee), the preferred candidate seems obvious. However, in our field plots #14458 produced 60% more biomass than #14447, which was an ‘average’ yielder. This higher level of production should be attractive to farmers who currently struggle to incorporate much in the way of legumes in their feed rations. So, which one would you prioritise?

I’ve added the links to the Genesys entries for the accessions in questions for people who want a bit more data to base their decision on. You can provide your input on Chris’ post, or right here and I promise to pass it on.

Nibbles: Ancient Mexican seedbank, Indian millets, Foraged foods, Soybean breeding, Apple breeding, Albanian heirlooms, Bangladesh fish genebank

  1. People in the Nejapan Sierra Sur in Oaxaca, Mexico had a seed bank 400-700 years ago so they could re-create their complex cuisine after disruptions.
  2. How MSSRF revived millets in Odisha, India. You think a seed bank was involved?
  3. Meanwhile, in Meghalaya (also India), foraged foods are helping to diversify state-provided school lunches and address chronic malnutrition. Talk about complex cuisine. Are all these species in a seed bank somewhere, though? Do they need to be?
  4. How the National Soybean Germplasm Collection at the Agricultural Research Service lab in Urbana, Illinois helped save soybeans in Iowa.
  5. University breeding programmes are keeping the apple afloat in the USA. That and genebanks.
  6. Farmers and agrotourism are bringing back some cool flavors in Albania. Well, that and the Albanian Gene Bank.
  7. Fish need genebanks too, and Bangladesh is on it. Did ancient Bangladeshis have them, I wonder?

A breed is a breed is a breed?

I feel maybe yesterday’s Nibble on the definition of a “breed” may have been a bit too laconic, even for me. So let me give a bit more context.

A ram and ewe of the South Down and Norfolk breeds of sheep. Etching, ca 1822. Created 1 June 1822. Cattle. Livestock – Breeding. Domestic animals. Livestock breeds. Rams. Ewes. Work ID: ytvy3rzq.

The link was to a YouTube playlist, which was described thus (link added):

The presentations in this playlist are from the webinar on “Genomic assessment of genetic variation and the future of the breed concept”, originally held on 12.12.2024 under the umbrella of the Food and Agricultural Organization (FAO). This represents the culmination of collaborative work by a diverse group of experts from institutions from all around the world to prepare materials for a sub-chapter in the upcoming 3rd Report on the State of the World’s Animal Genetic Resources for Food and Agriculture.

It amounts to over an hour of talks, but if I had to summarize the point the playlist is making, it is that genomics is redefining a breed as a fluid, porous, genotypically-characterized population rather than a fixed, pedigree-based, phenotypic entity. Thus, it is shifting livestock conservation from saving labels (“Breed A”) to preserving genetic options.

Here’s a handy table I came up with to describe the change:

Interesting to juxtapose this to the post a few days ago on how to value and use Indigenous knowledge to solve today’s problems. Would Indigenous livestock keepers necessarily care about those genetic options more than their traditional breed?

It would be great to hear from people engaged in livestock conservation on this. It’s unfortunately not a community I interact with much.

Nibbles: Supermarkets, Cate Blanchett, ABS, Transformation, Medieval haymaking, Aurochs rewilding, Breed concept

  1. What’s wrong with supermarkets.
  2. Cate Blanchett on the Millennium Seed Bank. Attitude to supermarkets unknown.
  3. Access & Benefit Sharing 101. Cate Blanchett unavailable for comment.
  4. Experts weigh in on how we should change how we eat. Nobody but Cate Blanchett will listen, but supermarkets and seeds feature, for what it’s worth.
  5. How they ate in the Middle Ages without supermarkets. Or at least harvested.
  6. After we’re done with medieval haymaking, let’s bring back the aurochs too. And put it in a supermarket?
  7. Yeah but what is a breed anyway? Or an aurochs, for that matter.
