- Molecular Markers for Genetic Diversity Studies in African Leafy Vegetables. Not surprisingly, only 3% of 33 studies since 1998 are on Cleome, more than half on cowpea. And a quarter used RAPDs. Orphan crops, anyone? These one don’t even get a table summarizing and comparing findings across species.
- Conservation priorities of Iberoamerican pig breeds and their ancestors based on microsatellite information. Depending on how you crunch the genetic numbers, Iberoamerican pig breeds could conceivably best be looked after by conserving their ancestral Iberian pig breeds. But it’s not just about the genetics, is it?
- Native fruit tree genetic resources in Japan. Only a Castanea was domesticated in pre-modern times, and they’re all endangered in post-modern times.
- Perceptual selection and the unconscious selection of ‘volunteer’ seedlings in clonally propagated crops: an example with African cassava (Manihot esculenta Crantz) using ethnobotany and population genetics. It’s seedlings that look most like existing varieties that farmers try to keep.
- Changes in sunflower breeding over the last fifty years. From yield under optimal conditions to disease resistance, from oil quantity to quality. But international collaboration still needed.

AVGRIS revamped
The World Vegetable Center has come up with a redesigned front-end for presenting data on its germplasm collection to the world.
The AVRDC Vegetable Genetic Resources Information System (AVGRIS) is an information system that manages the data of all vegetable germplasm conserved in the AVRDC genebank. The Genetic Resources and Seed Unit uses this system to efficiently manage genebank operations. AVGRIS links all germplasm conservation and management operations, from registration, characterization, evaluation and seed inventory to seed distribution to end-users.
Check it out. And before you ask, no, I looked, and Varrone is not there.
A tomato comes back home
The return to its native land of an historic tomato variety developed by the famous wheat breeder Nazareno Strampelli is making a splash in Italy. Originally published in the rather specialized organ L’Iformatore Agrario, the news has now been picked up by the more mainstream media, at least regionally.
What’s particularly interesting to us here is that Varrone, as the variety is called, was eventually found in the genebank of the Vavilov Institute, in St Petersburg, Russia.
“It is a small tribute to the memory of Strampelli on his 150th birthday: from tomorrow it will be possible to eat spaghetti Cappelli-Varrone, 100% Strampelli, not only for the durum wheat but also for the tomato sauce,” says Roberto Papa, professor of agricultural genetics at the Università Politecnica delle Marche, who coordinated the research in collaboration with Sergio Salvi, biologist and biographer of Strampelli, and Giovanna Attene professor of agricultural genetics at the Università di Sassari.
The durum wheat variety Senatore Cappelli was also bred by Strampelli in the 1910s, and remained popular for decades. I’m sure Strampelli would have been pleased that his tomato has been found. Not so sure what he would have thought about losing it in the first place.
