Abstract

In the late 1970's, Korean production of potatoes, a staple and more recently a cash crop, fell sharply due to the failure of Korea's Seed Potato Certification Program to control the spread of potato virus diseases, even among its own foundation seed stocks. In response, the Korean Government reorganized the program, establishing a Basic Seed Production scheme that used tissue-culture for producing, storing, and rapidly multiplying virus-free planting material. Techniques for field multiplication, inspection, and pathogen testing of foundation, registered, and certified seed were also improved. The new program has sharply reduced virus disease symptoms in farmers' fields and increased yields from an average of 11 t/ha to over 18 t/ha. Despite this success, only about 15% of the seed potatoes in use are certified; benefits could be maximized if the program were better integrated with the farmers' informal seed system. Other potential program reforms include clarifying the responsibilities of participating institutions, strengthening technical capacity to inspect and certify seed, and eventually transferring responsibility for seed production and marketing to the private sector.
