Abstract Wheat production in Ethiopia faces numerous climate related constraints that entail development and dissemination of wheat germplasms with yield stabilizing traits under climate related challenges such as frost, drought, and yellow rust. The adoption of the germplasms will however depend on the effective demand of wheat growers. This study investigates the preferences and willingness to pay (WTP) for frost and yellow rust resistance, grain yield, grain color, plant height, and length of maturity traits of wheat in Ethiopia. A choice experiment method was used to generate 8181 observations from a random sample of 303 smallholder farm households. We report mean WTP values, preference heterogeneity and attribute non-attendance patterns based on different formulations of the mixed logit model. The results revealed that farmers are willing to pay for yellow rust resistance, frost resistance, increase in grain yield, and white grain color (cf. brown). Farmers showed disinterest in increase in length of maturity and black grain color (cf. brown). Farmers have high WTP for yellow rust resistance and frost resistance traits, which is nearly 10 times the value they are willing to pay for increase in grain yield of 100 kg per hectare. Similarly, farmers are willing to pay for harvesting wheat yield a month earlier a price four times the value they attach to increase in grain yield of 100 kg per hectare. The weight farmers attach to climate related traits of wheat show the importance farmers implicitly give to the climatic factors they must consider in their wheat production. Therefore, carefully developed wheat varieties would improve the effectiveness of the climate change adaptation strategies of smallholder farmers.

农民愿意为小麦的气候相关特性买单吗？来自埃塞俄比亚农村地区的证据

摘要 埃塞俄比亚的小麦生产面临许多与气候相关的限制，需要在霜冻、干旱和黄锈病等气候相关挑战下开发和传播具有产量稳定特性的小麦种质。然而，种质的采用将取决于小麦种植者的有效需求。本研究调查了埃塞俄比亚小麦对抗霜冻和黄锈病、粮食产量、籽粒颜色、株高和成熟长度等性状的偏好和支付意愿（WTP）。选择实验方法用于从 303 个小农户的随机样本中生成 8181 个观察结果。我们报告了基于混合 logit 模型的不同公式的平均 WTP 值、偏好异质性和属性不出席模式。结果显示，农民愿意为抗黄锈病、抗冻性、增加粮食产量和白色粮食（比棕色）买单。农民对成熟期和黑色谷物颜色（比较棕色）的增加不感兴趣。农民对抗黄锈病和抗冻性状的支付意愿较高，几乎是每公顷粮食增产100公斤所愿意支付的价值的10倍。同样，农民愿意为提前一个月收获小麦产量而支付的价格是他们对每公顷粮食产量增加 100 公斤的价值的四倍。农民对小麦气候相关性状的重视表明农民对他们在小麦生产中必须考虑的气候因素的重视。所以，
