- Genetic diversity and phylogeography of broomcorn millet (Panicum miliaceum L.) across Eurasia. One origin or two? Moving east or west? We still don’t know, but crop wild relatives may tell us.
- Next-generation sequencing for understanding and accelerating crop domestication. Those who understand history may be able to repeat it.
- Competition among loblolly pine trees: Does genetic variability of the trees in a stand matter? Can’t really say either way.
- The potential of South African indigenous plants for the international cut flower trade. Could do better.
- Genetic variability of banana with ornamental potential. The Embrapa Musa collection has some really cool-looking plants.
- Cytological Behavior of Hybridization Barriers Between Oryza sativa and Oryza officinalis. I guess that’s why they call it the tertiary genepool.
- Ancient lipids reveal continuity in culinary practices across the transition to agriculture in Northern Europe. Crap on 6000-year-old ceramic vessels shows people in the Western Baltic continued to eat fish and clams even after agriculture arrived. Well do you blame them?
- Options for support to agriculture and food security under climate change. Show ’em yer multi-pronged strategies, that’ll get their attention.
- N.I. Vavilov’s Theory of Centres of Diversity in the Light of Current Understanding of Wheat Diversity, Domestication and Evolution. When genes flow from centre of origin, that centre will not coincide with centre of diversity.
A personal view of the international rice collection at IRRI
Written, directed and produced by a former curator, Mike Jackson. Genebank videos could be a whole sub-category at the Oscars.

The John Innes Centre announces on Facebook that, on the latest episode of the BBC2 programme Great British Food Revival, the Centre’s genebank curator, Mike Ambrose…
…talks to celebrity chef Ainsley Harriot about peas, and introduces him to the JIC collection of 3,500 types of pea. Available in the UK until 6:59PM Tue, 22 Nov 2011 (pea segment starts after 29 mins).
Alas, not available here in Italy. Can someone in the UK watch the pea segment and tell us about it, please? The JIC pea collection is one of the largest in the world.
LATER: Or, you can watch this: ((Thanks to whoever tweets for John Innes!))

Getting one’s oats right
Luigi rapidly found me hundreds of accessions in genebanks around the world.
Alas, Luigi was looking for the wrong thing. As Axel Diederichsen succintly explains in a comment to Jeremy’s post of a couple of days back on naked oats.
The name Avena nuda L. refers to the small naked oat, a diploid species, while the naked oat talked about in this article is hexaploid and should rather be called Avena sativa subsp. nudisativa (with quotation of the authorities it will be: Avena sativa L. subsp. nudisativa (Husnot.) Rod. et Sold.). (Reference: Kobylyansky V.D. and Soldatov V.N. 1994. Flora of cultivated plants, vol. 2 part 3, Oat. Kolos, Moscow).
I had searched for Avena nuda, not Avena sativa subsp. nudisativa. Silly me. So it’s back to Genebank Database Hell for me. Needless to say, the subsp. nudisativa is unknown to any of the genebanks I checked, but that’s ok, because the hulless trait is a state in an official characterization descriptor for oats, and GRIN in both the USA and Canada allows a search on characterization descriptor states.
So now I know there are 375 hulless accessions in the US germplasm system and 262 in Canada, in both cases out of over 10,000 Avena sativa accessions. So my original statement turns out to be still true, though rather by luck than judgement. I know what you all want is a map of where those naked hexaploid oats come from, but that’s going to be really, really tricky until Genesys imports the oat characterization data.
