dc.description.abstractCooperation-88 (C88) is a late blight resistant potato variety that was formally released in China in 2001 and has become popular in China's Yunnan Province. The International Potato Center (CIP) and Yunnan Normal University collaborated to produce the variety, which is one of CIP's most successful varieties. C88 is popular due to its high quality and taste, and it is used commonly in China's expanding potato chip processing market. The purpose of this study is to examine adoption of C88 in the Yunnan Province, its value chain, and economic impacts. The analysis indicates that C88 is still popular with 16.8% of the potato area in Yunnan devoted to this variety in late spring 2015. To examine factors affecting household decisions to adopt and the intensity of their adoption, village adoption, household adoption, and household intensity of adoption were assessed. A village's proximity to a metropolitan county was the most important factor explaining adoption and intensity of adoption. Households in villages closer to a metropolitan county disadopted at higher rates than those farther away. To quantify the economic benefits of C88 adoption, an economic surplus analysis was conducted. Total surplus changes ranged from $2 to 3 billion indicating significant economic benefits to consumers and producers in Yunnan.en
dc.description.abstractgeneralCooperation-88 (C88) is a popular late blight resistant potato variety that was released to the Yunnan Province of China in 2001. Late blight is the disease responsible for the Great Potato Famine in Ireland. The International Potato Center (CIP) and Yunnan Normal University collaborated to produce the variety, and C88 is one of CIP’s most successful varieties. C88 is popular due to its high quality and taste, and it is used commonly in China’s potato chip processing market. The purpose of this study is to examine the number and types of people who adopted C88 in the Yunnan Province, provide an understanding of the process from farm to consumer, and to determine the economic impacts of the variety. A major finding of the study is that C88 remains popular in Yunnan as of spring 2015. To study the households that grew C88 during the spring 2015 season, statistical analysis was conducted with the focus on what household traits influence the number of surveyed households who grow C88 in a village, whether a household grows C88, and the number of hectares under C88. A village’s proximity to a metropolitan county was the most important factor explaining whether a household adopted the variety and the number of hectares. Households in villages closer to a metropolitan county stopped growing C88 at higher rates than those farther away. To quantify economic benefits, a supply and demand analysis of potatoes in Yunnan was conducted, which indicated significant economic benefits to consumers and producers in Yunnan.en
