Maize field day in Mexico

Dr Denise Costich, head of the CIMMYT maize genebank (MGB) sent out a very compelling invitation a couple of days back:

Attached is the official invitation to our field day, to be held next Friday, 21 November, starting at 10:00 AM at the Toluca Station (please note the change of date). We are showcasing our beautiful materials from the high altitude Andean germplasm that, up to now, the MGB has had great difficulties in regenerating here in Mexico. We also included a demonstration plot in our nursery, featuring long forgotten genetic pools developed at the Toluca Station in the 80s and 90s, as well as, popcorns, cacahuacintles, and other landraces from the region. We are targeting the smallholder farmers from areas around 2600 masl and above. We couldn’t have done this without funding from the Global Crop Diversity Trust and ICAMEX. We also thank the Toluca Station Manager, Fernando Delgado, for his great support, interest, and encouragement. Thanks also to Hans Braun, who extended an invitation to the “maiceros” of CIMMYT to plant at this wonderful station… I’m sure I have missed people who might be interested in attending the field day. You are welcome to forward this invitation to them. However, everyone, please RSVP, so that we have enough food and catalogs!

It sounds like great fun, and I wish I could go, but I can’t. Maybe you can?

Brainfood: Basil resistance, Maize quality & drought, Benin sorghum, Swedish farm size, E European grapevives, Lebanese olives, Brazilian sheep, Sudanese cattle, Egyptian bean rhizobia, Barley origins, Intercropping

Selecting basil genotypes with resistance against downy mildew. Only the exotic basils were any good. I will resist the temptation to make Fawlty Towers jokes.
High grain quality accessions within a maize drought tolerant core collection. Not so much a core collection, rather a set of local and exotic drought-tolerant varieties put together in the former Yugoslavia. Some of which turn out to have decent quality too.
Diversity, genetic erosion and farmer’s preference of sorghum varieties [Sorghum bicolor (L.) Moench] in North-Eastern Benin. Climate change, poor soils and striga are the main problems, according to farmers, and none of their current varieties will help much, apparently, which is why they are disappearing.
Effects of Farm Size and On-Farm Landscape Heterogeneity on Biodiversity—Case-Study of Twelve Farms in a Swedish Landscape. Small farms = heterogeneous farms = biodiversity-rich farms.
Identification and characterization of grapevine genetic resources maintained in Eastern European colletions. SSR revealed that of 1098 mainly Vitis vinifera accessions, 997 were indigenous to E. Europe, 101 were Western European cultivars, hybrids, rootstocks and new crosses; the 997 accessions were actually 658 unique cultivars, 54% of which were maintained in the countries of origin only.
Extent of the genetic diversity in Lebanese olive (Olea europaea L.) trees: a mixture of an ancient germplasm with recently introduced varieties. Three genetic groups around the Mediterranean, most Lebanese material typical of the eastern group; monumental trees similar to Cypriot varieties. In other news, there’s a World Olive Germplasm Bank of Marrakech.
Application of microsatellite markers for breeding and genetic conservation of herds of Pantaneiro sheep. Evidence of inbreeding means a proper genetic management scheme needs to be designed and implemented.
Historical demographic profiles and genetic variation of the East African Butana and Kenana indigenous dairy zebu cattle. The only indigenous African dairy breeds, apparently, but with distinct genetic histories despite their similar distribution in Sudan and dairy use.
Phylogenetic multilocus sequence analysis of native rhizobia nodulating faba bean (Vicia faba L.) in Egypt. Three species, and evidence of horizontal gene movement among them.
Transcriptome profiling reveals mosaic genomic origins of modern cultivated barley. The Fertile Crescent and Tibet.
Improving intercropping: a synthesis of research in agronomy, plant physiology and ecology. You can breed for it. Among other things.

Outstanding Papers in Plant Genetic Resources 2014

…early this month the Crop Science Society of America (CSSA) has selected the paper ‘Improving Hierarchical Clustering of Genotypic Data via Principal Component Analysis’ for the 2014 award for ‘Outstanding Papers in Plant Genetic Resources’.

The paper is the result of a collaboration between Biometris and the Centre for Genetic Resources, the Netherlands (CGN): “The result of these two worlds meeting is influential science and efficiently managed germplasm.” Congratulations to Thomas Odong and his co-authors.

Nibbles: Easy Eleusine, Ethical down, Bison pix, Svalbard pix, Salinity costs, Nutrition conference, Veggies for nutrition

Finger millet is the future in Zimbabwe.
Conventional down has a problem. I do prefer unconventional down myself.
They had National Bison Day and nobody told us.
Epic’s Excellent Svalbard Adventure.
Start planning for next year’s cucurbit conference.
Soil salinity sucks.
On the other hand, this nutrition conference is in only a couple of weeks. And there will be radio.
Not that these Indonesian ladies will need that.
