A review of taro (Colocasia esculenta) (L.) Scnott) genetic resources of Papua New Guinea.

Abstract

The status of taro (Colocasia esculenta (L.) Schott) genetic resources and the efforts of the National Agricultural Research Institute, together with several regional networks, in the acquisition, conservation, evaluation and utilization of the germplasm are reviewed. Wild and cultivated genotypes show enormous genetic variation suggesting Papua New Guinea is a centre of diversity. However, traditional varieties are being displaced due to biotic and abiotic factors. A representative sample of the genetic diversity of taro in Papua New Guinea has been collected and is maintained ex situ. The need to develop alternative conservation strategies for efficient management and utilization are considered.
