AbstractRubus hyrcanus is considered as an important wild blackberry species scattered around the Caspian Sea. In this research, ISSR and morphological markers were used to assess genetic diversity in several populations of R. hyrcanus from various geographical regions of Caspian Sea in Iran. Twenty-five populations of R. hyrcanus from three regions (North- Western (NW), North- Eastern (NE) and Central (C)) and one population from R. discolor were applied in this research. Ten primers were used to amplify bands out of which 157 (77.13%) were polymorphic. Cluster and Principle coordinate analyses (PCoA) showed the higher similarity of NE and NW populations. Analysis of molecular variance (AMOVA) revealed that the differences among three collection regions only accounted for 28.09% of the total variation, whereas differences among populations within groups were 66.03%. Analyses among three regions showed that the minimum gene diversity over loci was observed in NW (0.16) and NE (0.17), while the highest one was found in C (0.238) region. Furthermore, narrow genetic base and relatively high genetic differentiation obtained for studied R. hyrcanus genotypes. The results of morphological analysis in most cases corresponded to those obtained through molecular analyses.

Abstract Mangrove forests are tropical and subtropical forests that grow typically along the coast or river estuaries. Black mangroves are a type of mangrove found in South Sulawesi, precisely in Maros, Pangkep, and Barru Districts. The decline in black mangrove populations overcomes the threat limit to germplasm which can lead to reduced genetic diversity in black mangrove plants. To reduce the incidence of extinction in black mangroves, information on genetic diversity using one of the markers is required, namely morphological markers in taking samples of tree parts taken, namely the leaves, stems, and roots which are then for monitoring carried out in the Biotechnology Laboratory and tree breeding. The method used in this study is based on the literature on the development of the Tropical Fruit Descriptor information system. The results of the three studies proved that there is a difference between the evidence and the interprovenencies. The very close morphological kinship between them proved to be found in Pangkep. Pangkep’s provenance has a high coefficient compared to the proof of Maros and Barru, which is at the time level of 70%, while the proof of Maros has the lowest coefficient compared to the proof of Barru and Pangkep, which is at the gathering level of 64%.
