Fruits and nuts

Giant fruit update

For some reason, this seems to be the time of year which the media sets aside for stories on large fruits. Or largish, anyway. Because I may be spoilt by my time in the tropics, but this “Avozilla” doesn’t look like such a big avocado to me. I was hoping I’d be able to be more precise about this, but I couldn’t find systematic characterization data on the world’s avocado collections, not even in GRIN. And no, I’m not impressed that Avozilla has its own Twitter account either:

“@DailyMailUK: AVOZILLA, world's largest avocado goes on sale at Tesco http://t.co/8wCZl4WiNA pic.twitter.com/gLEV98M0It” Yes, I'm here!

And likewise, 14-15 grams is not bad for an olive, but there’s bigger, and not all of them are from Italy.

Nibbles: Kenyan millet, Nutritious fruits, Homegardens, Schools, CIAT genebank funding

Millet helps sends Kenyan to college. Which millet though?
Some fruits, but not juice, good against diabetes. Coconut not included, alas. Nor bananas, for all their recently revised taxonomic goodness.
Which both seem as good reasons as any to grown your own.
And teach about them in schools.
And conserve them in genebanks. Ok, this piece from CIAT is about neither millets nor fruits, but it’s friday, gimme a break.

Nibbles: Golden Rizzzzzz, Agronomy meet, Pricey poultry, Pricey Indian food, Target environments, NUS galore, G&T

The Golden Rice thing rumbles endlessly on.
I wonder whether it was discussed at the First International Agronomy Day. I bet that fertilizer thing in Malawi was.
The world’s most expensive cock. Made you look!
I wonder whether you can select sex in chickens like you can in cattle.
Anyway, speaking of expensive agrobiodiversity, a celebrity economist rounds up links on Indian food price inflation. Must have seen our recent stuff on onions. But can you grow them on the roof?
The secret of breeding? Location, location, location.
List of “indigenous” fruits and vegetables of allegedly potential global importance without a damn scientific name anywhere. Annoying on many levels.
Mind you, this piece on the threats faced by the wild herbs of Crete also doesn’t have any names.
See, you can include a scientific name of an underutilized plant and not look unbearable geeky. Well, kinda. Although this press release on burgeoning collaboration on NUS manages to avoid mentioning even common names.
Oh I so need a drink.
And some cheese.

Nibbles: Citrus cryo, Vegetables everywhere, Threatened ecosystems, Brazilian ag, Native restoration, Regeneration video, Nomenclature, Grass pea, Tef, Millet, Hops, Kenyan rabbits, Bloody quinoa

Saving citrus by freezing it.
WorldVeg pushing tomatoes in the Solomons. New York next? Ah, but what they really need is Mind Gardens. Oh, and a how-to-save-seeds book. Or maybe just Jeremy’s latest podcast on breeding your own veggies.
Ecosystems get their red list too.
“Although there are some who consider Brazilian agriculture to be aggressive and destructive, we want to share another vision for the rest of the tropical belt…”
But if it’s too late, of course you can try to restore them.
Video of wheat regeneration in Canada. Like watching grass grow. No, wait.
The naming of plants, music to our ears.
Kew does Lathyrus sativus, grass pea to the rest of you, music to Luigi’s ears.
IFPRI is going great nutritional guns, with the low-down on tef and biofortified millet.
So, Big Picture Agriculture’s hop garden is flourishing.
Likewise rabbits in Kenya.
Enough already with the quinoa.

Brainfood: Touristic islands, Pearl millet diversity, Barley diversity, Maize diversity, Weird chickpea, Sweet potato diversity, Pawpaw diversity, Grewia domestication, Agrobiodiversity is the key, Sunflower relative dynamics

Sorry about the Brainfood hiatus lately. Back now, and with a vengeance.

Plant genetic resources in a touristic island: the case of Lefkada (Ionian Islands, Greece). Landraces and tourism can coexist.
Assessment of genetic diversity among pearl millet [Pennisetum glaucum (L.) R Br.] cultivars using SSR markers. The cultivars coming out of a given breeding programme cluster together. No!
Population genetic structure in a social landscape: barley in a traditional Ethiopian agricultural system. Farmer management trumps even altitude.
Environmental and social factors account for Mexican maize richness and distribution: A data mining approach. Oh no it doesn’t.
Identification of an upright peduncle and podding genotype in chickpea germplasm conserved in the National Genebank. That’s one out of 18,873.
Molecular, morphological and agronomic characterization of the sweet potato (Ipomoea batatas L.) germplasm collection from Mozambique: Genotype selection for drought prone regions. 6 out of 28 local genotypes are drought tolerant. No word on whether they’re yellow fleshed too.
Genotyping a large collection of pepper (Capsicum spp.) with SSR loci brings new evidence for the wild origin of cultivated C. annuum and the structuring of genetic diversity by human selection of cultivar types. The taxonomy is ok. Human selection is reflected by genetic diversity. A quarter of the accessions can be chosen which contain 97% of the genetic diversity. In other news, France has a collection of 1,300 peppers.
Phenotypic and Genetic Diversity of Papaya. Wild papayas from South America are closer to an allied genus than to the cultigen.
Grewia flavescens: a potential horticultural crop? Well, maybe.
Agricultural biodiversity as a link between traditional food systems and contemporary development, social integrity and ecological health. You need sustainable small farms tied into global markets for high value food crops and ecosystem services. Marx rolls over in his grave.
Proximity to agriculture alters abundance and community composition of wild sunflower mutualists and antagonists. Wild relative populations nearer to cultigen have more pollinators but fewer seed and leaf munchers than those further away. Not entirely sure what that means for in situ conservation, but I’m sure it’s something.
