International Potato Center (CIP), Annual Report 1989: Worldwide Potato and Sweet Potato Improvement

摘要

In the past year, the International Potato Center (CIP) has continued its emphasis on global regionalization, with increased research workloads in Latin America, Africa, and Asia. An emerging CIP priority is for collaborative teams to create improved varieties by crossing local potato varieties with materials from CIP. The annual report highlights major activities in each of the following CIP research thrusts: the collection, maintenance, and utilization of unexploited genetic resources; production and distribution of advanced breeding material; control of bacterial and fungal diseases; control of virus and virus-like diseases; integrated pest management; warm-climate potato and sweet potato production; cool-climate potato and sweet potato production; postharvest technology; seed technology; and food systems research.
