Featured: Wurzels and mangelwurzels

Brian Ford-Lloyd is excited about a recent Nibble, and who can blame him:

Brilliant BBC piece on the famous mangelwurzel of Somerset and a tribute to Adge Cuttler and the Wurzels. Supermarkets would need reinforced trolleys to stock them but I can see small holdings and pig fanciers growing them to feed their livestock. Plenty of seeds to be had in European genebanks, some collected by me, but they may be found under other names like mangolds or fodder beet. I’d love to visit the Somerset festival though — wonder where they get their seeds from?

Featured: Fresh for who, and at what price?

Jeremy rides his hobby horses in his comment on my recent ride on my own:

Good point, that improved varieties always depend on existing diversity yet those doing the improving seldom contribute to maintaining the diversity they depend on.

I would add a couple of my hobby horses.

Will ordinary Zimbabweans be able to afford these “fresh” blueberries? Will the blueberries even be available in Zimbabwe. And, as I swelter through another record-breaking heat dome, I’m reluctant to praise any effort that adds to GHG emissions, no matter how puny those may be in this case.

Featured: Too obvious?

Rather than “too good to be true”, this scheme is too obvious to happen. Stakeholders, public or private, do due diligence, especially if the “flagship project”, “demonstration case” or “experiment” runs into the hundreds of millions of dollars. This is of public concern.

That’s from Prof. Joseph Henry Vogel in reply to a recent(ish) post on decoupled ABS for PGRFA. Read the whole critique here.

Featured: Breeding with wild peanuts

David Bertioli points out, in a comment to a blog post about a recent paper of his, that there’s more than one way to use peanut wild relatives in breeding:

Your previous blog detailed the impact of Charles Simpson’s crosses in Texas, which used the “tetraploid route” of introgression which donated a chromosome segment from A09 which confers root knot nematode resistance. The PNAS paper focuses mostly on progeny from the North Carolina “hexaploid route”, which ended up traveling most around the world. These introgressions, from A02 and A03, confer resistance to Late Leaf Spot, Rust, and to a lesser extent Web Blotch.

Would be interesting to compare the impacts of the two “routes.”

Featured comment: Using genebanks

Important reminder from Maarten van Ginkel as part of a comment on yesterday’s post about the Australian genebanking publication.

We need strong awareness raising and encouragement to see gene banks not just as final resting places for historic exotic germplasm, but also as portals for highly needed useful genetic diversity for future introgression into modern crops.

Maarten was closely involved in both CIMMYT’s Wheat Genebank and the Australian Grains Genebank.
