Molecular genetic diversity of some eucalypltus and acacia hybrid varieties for breeding purpose of paper material trees
The research was conducted to characterize DNA molecular differences among eight Eucalyptus and three Acacia hybrid varieties belong to the collection of Research Institute of pulp and paper raw material tree species. The PCR-RAPD analyses used 32 random primers, results revealed that 17 RAPD primers expressed polymorphism. There are 751 and 263 DNA fragments obtained from eight Eucalyptus and three Acacia hybrid varieties, respectively. The data was processed by NTSYSpc and NTSYS version 2.1-SIMQUAL programs which showed out genetic similarity coefficient at the DNA level from 0.59 to 0.788 of Eucalyptus and from 0.628 to 0.757 of Acacia. Among eight Eucalyptus varieties analyses, PN7 had the highest coefficient of genetic variation compared with the others. The results of this research provided scientific data to contribute for the germplasm conservation and breeding of paper material trees.
