Summary
The results of an exploration and collection work on Psophocarpus tetragonolobus (L.) Dc. are presented. A wealth of genetic diversity in the Highlands of Papua New Guinea was uncovered, and experimental work resulted in isolation of 121 pure lines as the first germplasm collection. It is believed that it may not be indigenous to Papua New Guinea but that it has been introduced to this Island long before the first European contact. The implications of the finding for the development of this species in present and in future it discussed.
