Indigenous potato is linked to specific adaptations to local fanning system and specific agro ecological conditions. This research was conducted in Prishtina region which is located in the Kosovo agro ecological region （42°38′97″ latitude and 21°08′45＂ longitude at 574 m.a.s.l ）. Plant material used in this research was 18 potato accessions with different origins. The experimental design was a randomized complete block （RCB） with three replicates, while the plot sizes were 4.20 m^2. All observation and analysis were carried out on 12 plants from each accession. All characters were measured in the field and laboratory at the normal harvest time. Morphological diversity was characterized using standard descriptors. The genetic diversity studies of the investigated potato accessions showed significant genetic variation on 17 physiological and chemical parameters, which could be largely due to that they were of different origins. The genetic diversity of potato cultivars offers a wealth of natural resources from which breeders can select the most desirable genotypes based on their favorable traits.展开更多
