The principally ordered regular semigroups(for short POR-semigroups) with orthodox0 po-transversals were studied.It is proved that the class of POR-semigroups is a subclass of regular semigroups.The transversal theory of semigroups to po-semigroups was extended and the structure of POR-semigroups was described by virtue of orthodox 0po-transversals.
