†Present address: Department of Plant Pathology, Faculty of Agriculture, University of Guilan, 41635 1314, Rasht, Iran. Abstract Random amplified polymorphic DNAs (RAPDs) was used to estimate the genetic diversity between ans within three population of unknown provenances of loblolly pine plantation in Iran. Out of 50 primers, only 5 were able to detect polymorphism between 30 trees samples. Among the 71 bands generated by the selected primers, three were present among all the samples analysed and corresponded to monomorphic bands. The remaining 68 variable bands were selected as RAPD markers. The most and least polymorphism related to population B (planted stand) with 91.52% and population A (natural regenerated stand) with 87.32% respectively. According to genetic distance, dendrogram showed, the three populations divided into two groups. However, our results showed that the general level of genetic variability in unknown provenances of loblolly pine was low. Top Key words Lobolly pine, RAPD, genetic diversity. Top |
