Georgia (South Caucasus) has wild Caucasian pear (Pyrus caucasica) representing as relict and endemic species of the Caucasus. It is determined by molecular analysis as the ancestor of 15 pear landraces of Georgia. We used in situ and ex situ methods for conservation of P. caucasica, as crop wild progenitor and relative for pear varieties reeder. Wild Caucasian pear was determined as a crop wild relative species according to the results of the field works carried out in Georgia and this species received high conservation value. According to scoring system to establish scores of crop wild relative pear species revealed the following data: The threats of P. caucasica have been determined only as near threatened with score 2; The rarity of this species was calculated as frequency of 10×10 km and the number of individuals reaches till 20 with score 4; Endemism of this species is not only in Georgia but on the Caucasus ecoregion and score is 5; Gene pool and taxon group identification was related with score 10 according to molecular study of pear species. The analyses have revealed the tendency of P. caucasica to be have high score (21) and in the last criteria of this species has showing closely relatedness to famous 15 traditionally Georgian pear landraces.
