- Australia’s own genebanks are very serious. Oh yes indeedy.
- Will sweet potatoes get young people into farming in Kenya? If my nephews are anything to go by, the answer, alas, is no.
- Maybe they should try mungbeans.
- Or NERICA.
- The Bing cherry didn’t help Ah Bing much though.
- Whatever the crop, it’s total factor productivity that you have to watch for.
- And then don’t forget to include whatever intervention you come up with in subject-wide evidence synthesis.
- Prize for best title of the week: “Nordic cooperation on genetic resources – what’s the point?” Nice video.

- Molecular markers as a tool for germplasm acquisition to enhance the genetic diversity of a Napier grass (Cenchrus purpureus syn. Pennisetum purpureum) collection. Win-win for the ILRI and Embrapa genebanks.
- Women’s empowerment in agriculture and agricultural productivity: Evidence from rural maize farmer households in western Kenya. 1% increase in women’s empowerment led to a 6-16% increase in maize yields, depending on fanciness of math.
- A transcriptome screen for positive selection in domesticated breadfruit and its wild relatives (Artocarpus spp.). Evidence of selection in 1000 genes.
- A selfish genetic element confers non-Mendelian inheritance in rice. Pollen toxin-antidote genetic system controls hybrid sterility in wild-cultivated crosses.
