Abstract
Genetics and chemicals relatedness among three Euphorbia species (
Aiton,
. and
L.) were analysed by RAPD, ISSR markers and GC-MS technique. RAPD profiling pattern revealed that
and
.
in one cluster with similarity value (44.37%) while the lowest value (29.14%) between
and
.
. ISSR profiling pattern revealed that
.
and
.
in one cluster with similarity value (46.75%) and the lowest similarity value (37.87%) between
.
and
. The sum results of RAPD and ISSR data revealed that
.
and
.
in one cluster with similarity value (44.69%) while the lowest value (36.88%) between
.
and
.
. Sixty-eight chemicals pattern revealed that
.
and
.
in one cluster with similarity value (39.71%) while the lowest value (25.0%) between
.
and
.
. Super tree (RAPD, ISSR and phytocomponents) revealed that
.
and
.
in one cluster with similarity value (43.04%) while the lowest value (36.08%) between
.
and
.
. In conclusion, biosystematics tools including biomarkers and chemical compounds can be applied to investigate relatedness of Euphorbia species and probably to other plant taxa.
