      abstract = {Papua New Guinea has major ex situ field collections of  plant genetic material in its major staple food crops  (aibika, banana, cassava, sago, sweet potato, taro, yams).  The PNG Government has become concerned at the cost of  maintaining these collections. With limited germplasm  conservation resources available, difficult choices must be  made as to which plants to maintain. What resources should  be devoted to maintaining plant genetic diversity in the  wild or in collections. How should these resources be  allocated among various plant kinds, especially when some  of them are currently important in agricultural production,  whereas others may only be of potential future importance.  How should resources be allocated across the various  methods of conserving plant germplasm? Should genetic  collections only be maintained where the material has been  collected or should it also be stored in other countries. A  dynamic optimisation model is developed of the crop plant  improvement process, including selection from the wild and  farmers' fields, conventional plant breeding, the use of  advanced plant breeding techniques, and the contribution of  plant germplasm collections in the efficiency of this  process. The objective of the study is to provide a better  basis for evaluating the efficient allocation of resources  to plant germplasm conservation in food staples in PNG.},
