Solanum Tuberosum Andigena
For those running participatory varietal selection trials, how do you ensure genebank accessions actually make it into farmers’ hands and that their feedback comes back to the genebank?
Oryza Sativa Indica
CGIAR and partners have used PVS and newer “tricot” methodologies where farmers test multiple varieties in their own fields and rank them. Data from these trials — yield, taste, stress tolerance —feed back into breeding and can be linked to original genebank accessions. ( CGIAR)
Zea Mays Dentiformis
In our rice programme, we start with genebank material (often landraces or CWR - derived lines), pre -select promising entries, then run PVS with Farmer Field Schools. Accession numbers and DOIs travel with the seed packets, and farmer scores are stor ed in a database linked to GLIS. ( CGIAR)
Triticum Aestivum Spelta
From a farmer’s point of view, PVS works when criteria aren’t only about yield. We include cooking quality, fodder value, labour needs, and seed re -use. That’s where local landraces often shine, and sometimes they “win” over improved varieties. ( Alliance Bioversity International - CIAT)
Manihot Esculenta Crantz
There’s also a policy angle: PVS results can support the registration of farmer - preferred varieties (including those emerging from community seed banks) and justify investments in on -farm conservation. That links back to the Farmers’ Rights and community seed bank threads. ( CGSpace )
Phaseolus Vulgaris Pinto
For clonal crops like potato and sweetpotato, PVS is tightly connected to cryobanking. CIP, for example, restores cryo -stored material, multiplies it, and then tests it with farmers —closing a loop from cryo to field. ( Frontiers )
Cicer Arietinum Desi
Visualizing those loops in the Exchange —nodes for accessions, DOIs, PVS sites, farmer groups —would beautifully show how knowledge and germplasm flow between genebanks and communities.
