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.

Nibbles: Atlantic potatoes, Andean feasting, Lupin biodiversity, Vegetable grafting, Agrobiodiversity survey, Seed lending library, Lathyrus factsheet, Wild horses, School feeding

Tracing Canary Island potatoes back to the Andes.
Lupin diversity, all in one handy place.
Bangladeshi women are grafting away.
Wanna take a survey of “lessons learned about ways and means to conserve and use genetic diversity to build resilience to climate change in food and agriculture systems“? Uhm.
Maybe they should survey this guy.
Kew takes on the grasspea.
I have my freedom but I don’t have much time…
FAO spots a win-win-win in school feeding programme linked to family farms.

Nibbles: USNCGRP, Cherokee Purple, Excess urban bees, Bottarga, Cannabis

US listeners get an earful of the National Center for Genetic Resources Preservation.
And can read all about the history of one of the great heirloom tomatoes, Cherokee Purple.
You can’t have too many urban beekeepers, or can you …? Be warned, the full article is behind a paywall.
Floridian bottarga “tastes cleaner than the Italian stuff” shock.
Molecular diversity among Cannabis genomes. We say, “bring back the landraces”.

Nibbles: Sustainability, Decaffeinated coffee, Salep orchids, Conference, Negroamaro

The Sustainable Development Solutions Initiative wants your comments on its report Solutions for Sustainable Agriculture and Food Systems. You have till 15 August. h/t ILRI.
We can do you natural decaf, if you’re willing to risk losing the entire coffee crop to drought or insects.
Likewise, we can do you Turkish ice-cream, but you may have to do without some orchids in future.
I don’t suppose the January 2014 meeting on “Genetic Resources for Food and Agriculture in a Changing Climate” being organised by NordGen will be able to help, but it might.
I confess, I have found myself sipping a Negroamaro and wondering how it got that name.

Brainfood: Coloured wheat, Very wild wheat, Yam bean, Turkish pigeons, Impact of margarine, Refugia, GM and choice, Indian sorghum, Cameroonian oil palm

The anthocyanin content of blue and purple coloured wheat cultivars and their hybrid generations. In other news, there are blue and purple wheat cultivars.
Phylogenetic relationships and Y genome origin in Elymus L. sensu lato (Triticeae; Poaceae) based on single-copy nuclear Acc1 and Pgk1 gene sequences. It’s a very diverse genus, probably polyphyletic, and has exchanged genes with Aegilops/Triticum in the past. And could again in the future, presumably.
Microsatellite Markers for the Yam Bean Pachyrhizus (Fabaceae). They work, both on the 3 (sic) cultivated species and 2 wild relatives.
The domestic livestock resources of Turkey: inventory of pigeon groups and breeds with notes on breeder organizations. 72 breeds? Really?
Land use impact assessment of margarine. Land occupation by the crops involved has a bigger impact on ecosystem services and biodiversity than the transformation process.
Bio-cultural refugia — Safeguarding diversity of practices for food security and biodiversity. Important for food security locally, but also because of the memories of how the “surprises of the past” were handled.
Farmer’s choice of seeds in four EU countries under different levels of GM crop adoption. More GM adoption = less choice. For maize in 4 European countries anyway.
Sorghum landraces patronized by tribal communities in Adilabad district, Andhra Pradesh. And now safe in NBPGR too.
Molecular characterization of oil palm Elaeis guineensis Jacq. materials from Cameroon. It’s all one big populations, and you don’t need that many accessions to represent the whole.
