Fig.7 Single nucleotide polymorphisms (SNPs) which is specific to Rhizophora mucronata, Rhizophora apiculata and Putative hybrid in 3 Nucleus regions (DLDH SBE2 and FMRrm11) Fig.8 Single nucleotide polymorphisms (SNPs) which is specific to Rhizophora mucronata, Rhizophora apiculata and Putative hybrid in chloroplast region (atpB-rbcL intergenic spacer) IV. CONCLUSIONS The SNPs identified at three nuclear regions, indicated that the putative hybrid of Rhizophora found at SIEP is a natural hybrid of R. apiculata and R. mucronata. SNPs from the chloroplast region indicated that the mother tree of this hybrid was R. mucronata. Thus we suggest that this hybrid be named as a natural hybrid of R. mucronata and R. apiculata (R. mucronata x R. apiculata). The hybrid vigour detected in this putative hybrid point to its potential value in mangrove reforestation programs.
