On average the gene diversity was and the number of alleles per locus was . Only of the total genetic diversity resided among populations with a mean genetic distance among populations of The populations could be assigned to two geographic groups a large one containing populations from the eastern Alps as well as from Poland and Czechoslovakia and a rather restricted one with a single population from the Western Alps. The most homogeneous populations are those from eastern Europe Poland Sudetan region and Tatra mountains . Larix decidua I allozymes I genetic variation Résumé Variation génétique du mélèze d Europe Larlx decidua Mill . Le niveau de diversite de 7 marqueurs génétiques a été étudié en électrophorèse pour 7 populations representatives de la variation naturelle du Larix decidua Mill . En moyenne la diversité génétique était de 0 223 et le nombre d alldles par marqueur 2 28. Seulement 5 1 de la diversité génétique totale étaient repré-sentés dans des populations d une distance génétique moyenne entre populations de 0 029. Les populations purent être assignées à 2 groupes géographiques dont run le plus important comprend les populations des Alpes orientales ainsi que celles de Pologne et de Tchécoslovaquie alors que I autre plus réduit ne comprend qu une seule population des Alpes occidentales. Les populations les plus homogènes sontcelles d Europe orientate Pologne Sudètes chaine du Tatra .
