Περίληψη:	Low elevation Mediterranean pines of the group halepensis are valuable and promi nent forest tree species with wide distributions across the Mediterranean basin. The natural distributions of the two species in Greece are well defined and distinct. They hybridize naturally though in the Chalkidiki peninsula, where Pinus halepensis Mill. meets the easternmost limit of its distribution in the Mediterranean basin. A network of experimental trials has been established in Greece for P. halepensis, as well as for P. brutia, to explore the levels of the existing variation for adaptive traits. Both P. halepensis and P. brutia provenances exhibited significant genetic varia tion for all the adaptive traits studied, while their performance across sites indicated the high potential for effective across sites selection. Also, P. brutia provenances of Greek origin outgrew the provenances originating from Turkey and Cy prus, when tested in two different sites. The outstanding performance of P. brutia x P. halepensis hybrids is worth mentioning, as when tested to gether with their parental species in harsh envi ronmental conditions they significantly outper formed the only parent that was able to survive (P. brutia). The results indicate the existence of ample genetic variation among and within the natural populations of both species for adaptive traits, the potential for selection and breeding, and the need for conservation of their unique genetic resources in the face of climate change.
