尽管就地保护越来越被认为是保护植物遗传资源的有效方法，但人们对发展中国家小农场主保护决策的激励和限制因素知之甚少。我们采用选择实验方法，调查了埃塞俄比亚农民的作物品种偏好，估计了每种作物品种属性的平均支付意愿，并确定了影响偏好的家庭特定因素和制度因素。我们发现环境适应性和产量稳定性是农民选择作物品种的重要属性。农民愿意放弃一些额外的收入或产量来获得更稳定、更适应环境的作物品种。其中，家庭资源禀赋（特别是土地拥有量和牲畜拥有量）、多年耕作经验以及与推广服务的联系是造成家庭作物品种偏好异质性的主要因素。根据我们的实验结果，我们得出了对埃塞俄比亚农场保护、育种优先顺序设定和改进品种采用的重要政策影响。 (C) 2010 Elsevier B.V. 保留所有权利。
Although in-situ conservation is increasingly considered an efficient way of conserving plant genetic resources, little is known about the incentives and constraints that govern conservation decisions among small farm holders in developing countries. Using a choice experiment approach, we investigated Ethiopian farmers' crop variety preferences, estimated the mean willingness to pay for each crop variety attribute, and identified household-specific and institutional factors that governed the preferences. We found that environmental adaptability and yield stability are important attributes for farmers' choice of crop varieties. Farmers are willing to forego some extra income or yield to obtain a more stable and environmentally adaptable crop variety. Among other things, household resource endowments (particularly land holdings and livestock ownership), years of farming experience, and contact with extension services are the major factors causing household heterogeneity of crop variety preferences. Based on our experimental results, we derived important policy implications for on-farm conservation, breeding priority setting, and improved variety adoption in Ethiopia. (C) 2010 Elsevier B.V.
