Congruence Between Morphological and Molecular Approach in Understanding Species Relationship in Ipomoea spp.: A Rare Event in Taxonomy
Saubhik Das

Abstract:
Taxonomic interpretations are based on some evidences. In biosystematics along with conventional morphological parameters, now-a-days molecular markers are extensively used in solving taxonomic disputes. There may be congruence or conflict between these two approaches. In the present study with twelve species of Ipomoea, general plant morphological character states as well as RAPD fragment phenotypes were employed to reflect interrelationship and clustering pattern of the species. Species pairs showing significantly greater pairing affinity values in morphological analysis also revealed higher monomorphism in RAPD band profile. Among the species I. hispida showed least number of amplified fragments (73) whereas, I. aquatica revealed highest number of amplified fragments (213). Dendrograms computed from morphological and RAPD data showed definite clustering pattern of Ipomoea species and significantly alike relative closeness. Present study revealed a sharp congruence between morphological and molecular approach.
