Potato onions (Allium cepavaraggrega-tumG. Don) are multiplying or aggregating onions,very similar to shallots and have been historicallycultivated throughout Europe. Currently in NorthernEurope they are maintained in home gardens and exsitu field collections. Potato onions are primarilyvegetatively propagated, however in Estonia, nearLake Peipsi, this species has been propagated by seedsince the seventeenth century. There is increasinginterest in Northern Europe in utilizing this germplasmin organic and/or sustainable farming systems. Thegenetic diversity and relationship between and withinEuropean potato onion collections is unclear. Fromhistorical records it is known that cultivation,exchange and trade of potato onion has occurredthroughout Europe for hundreds of years. This studyutilised molecular markers to assess genetic diversity,duplication of genotypes and relationships among andbetween Nordic, Baltic, Czech and Croatian potatoonion collections. Of 264 accessions, 80 catalogued asunique had identical genotypes with one or more otheraccessions, and are putative duplicates. The geneticdiversity within two Estonian sexually propagatedaccessions was comparable to that found in all of the vegetatively propagated accessions. Accessions from the Nordic countries grouped together genetically, as did Latvian and Lithuanian accessions. Croatian accessions were genetically separated. These genetic relationships suggest historical movement of potato onion germplasm in North-Eastern Europe. The results, in conjunction with other passport and characterization data, can assist in the development of potato onion core collections, facilitating the conservation and utilization of valuable potato onion genetic resources.

Nordmenn spiser i gjennomsnitt 6 kg løk i året. Det er lavt sammenlignet med de fleste andre land, men er likevel en økning fra ca 4 kg for 10-15 år siden. Det har blitt jobbet mye i verdikjeden for løk i Norge, med fokus på kvalitet, mangfold og kunnskapsdeling. Løk har fremfor alt god smak, men er også en av de sunneste grønnsakene. Løk anbefales spesielt som en av 5-om-dagen på grunn av sine gode dokumenterte helsevirkninger.
