Assessment of genetic diversity of garlic accessions from Croatia by SSR markers

Garlic (Allium sativum L.) is a vegetatively propagated vegetable extensively studied due to its beneficial health effects. The cultivation and use of garlic is a part of Croatian tradition and each region or even village has their own landraces preserved for generations. In a relatively small area, a high phenotypic diversity could be observed and therefore the aim of this study was to assess a genetic diversity of collected Croatian garlic accessions. We genotyped 43 accessions from three Croatian regions (Istria, Dalmatia and continental Croatia) along with 14 foreign landraces using six polymorphic SSR markers. The number of distinct genotypes has been determined and the genetic structure and relationships among the accessions have been accessed. This is the first attempt to evaluate a large set of garlic accessions maintained by Croatian institutions as a part of the National program for conservation and sustainable use of plant genetic resources for food and agriculture. Accompanied by morphological and biochemical description, the results of this study will contribute to better knowledge on garlic genetic resources and foster effective and sustainable management of Croatian collections.
