Yes, we have bananas

banana catalog What better way to start the new year than with an attractive catalog of banana accessions from USDA? Especially as, coincidentally, the Musa Germplasm Information System also debuts a new iteration of the website. This from a Facebook post today:

It is now possible to order ITC accessions from MGIS, an online database on genebank accessions of wild and cultivated bananas. The latest release also added information on 1,288 accessions for a total of 3,630 accessions maintained in 11 field and in vitro collections.

That Mai’a Maoli Eka cultivar in the photo from the USDA catalog of course features in MGIS, so you can order it if you like the look of it…

Ah no, wait. According to GRIN, it’s not available. Bummer.

Brainfood: Grazing, Dung beetles, Intensification, Pineapple diversity, Grassland N

Behavioural Response of Pure Ankole and Crossbred (Ankole x Holstein) Cows to Seasonal Pasture Variations in Southwestern Uganda. The cross-bred cows have to eat for longer than the local breed, which makes for problems during both wet and dry seasons.
Functionally rich dung beetle assemblages are required to provide multiple ecosystem services. It’s not just about the dung removal. No word on whether cross-bred dung tastier.
Swiddens under transition: Consequences of agricultural intensification in the Amazon. Intensification without diversification is going to be a problem.
Developing single nucleotide polymorphism markers for the identification of pineapple (Ananas comosus) germplasm. High redundancy in the USDA collection, and little correspondence between horticultural classifications and genotyping.
Grassland biodiversity bounces back from long-term nitrogen addition. Pollution bad for grassland biodiversity, stopping pollution good for grassland biodiversity.

DivSeek calling

Do you know of projects genotyping or phenotyping crop germplasm on a massive scale? Well, because the folks at DivSeek are collating that kind of info for a “landscape study.” Leave comments here and I’ll get it to them.

Brainfood: Wild rice database, E Asian wheat diversity, Microbial terroir, Sesame breeding, Agrobiodiversity fairs, AnGR conservation, Rye diversity

OryzaGenome: Genome Diversity Database of Wild Oryza Species. Well, only 2 species thus far, but it’s a start.
Evaluation of East Asian landrace wheat revealed by high molecular weight glutenin and maturity period. The Chinese accessions are different to the Japanese-Korean, and 3 of the former have both good gluten composition and early maturity, making them attractive to Korean breeders.
Sequence-based Analysis of the Vitis vinifera L. cv Cabernet Sauvignon Grape Must Mycobiome in Three South African Vineyards Employing Distinct Agronomic Systems. Even microbes contribute to terroir.
Genetic Diversity, Population Structure, and Association Mapping of 10 Agronomic Traits in Sesame. Some markers will be really useful in breeding.
The fairs of agrobiodiversity in the context of participatory plant breeding — Local Agricultural Innovation Program in Cuba. Meaning and impact. Diversity will find a way.
Biobanking genetic resources: Challenges and implementation at the USDA National Animal Germplasm Program. Everything that’s not cattle and swine is a problem.
Geography and end use drive the diversification of worldwide winter rye populations. There may have been multiple domestications, and improvement has not led to decrease in diversity.

Nibbles: Ancient faba, Ampelography double, S. African cattle, CIMMYT in Ethiopia, Seed pix, Heirloom pix, Trifolium genome

Faba beans came before cereals in Galilee.
Wine is not quite so old in Georgia, but still pretty old. But will they be able to genotype it?
South Africa is a cattle melting pot.
Getting improved wheat out there in Ethiopia.
These seeds are definitely ready for their close-ups.
Speaking of close-ups: Amy Goldman has a new book out.
First forage clover genome. More and more difficult to think of firsts.
