Abstract:
It is useful to identify the genetic variation among the Hevea genotypes in rubber breeding and
selection. Studies were conducted to identify RFLP markers for the detection of genetic variation
of rubber clones recommended for planting by the Rubber Research Institute of Sri Lanka.
Putative repetitive DNA sequences previously identified from a Hevea genomic library were
used, to probe genomic blots derived by digesting with six restriction enzymes.
DNA probes used in this study revealed genetic polymorphism among Hevea clones studied.
Clear genetic differences were identified in clones RRIC 102, RRIC 121 and GPS 1 (42-559).
