Human influence on biodiversity of cultivated and related wild species is high. In order to be able to use genetic variability of cultivated and related wild species it is necessary to preserve it by collecting wild relatives and by evaluating the genetic variability. Genetic integrity (GI) is an important index of biodiversity of each species. It presents a ratio between the total number of collected species samples on the same area at two sampling dates. The results of three expeditions performed from 1984 to 1991 at the area of former Yugoslavia were used. Seven species of genus Aegilops, which are still present in the collection of the Institute of Field and Vegetable Crops in Novi Sad, Serbia (Yugoslavia), were specially investigated. It was found that the most stable species was Aegilops triaristata with GI=80%, while Aegilops columnaris was lost (GI=0%). Further investigation on areas which were not covered here is necessary to show the real biodiversity of the genus Aegilops.
