目的-本文的目的是探讨发展中国家农民在生物强化主食作物商业化之前对其的接受程度。本文的重点是假设在印度马哈拉施特拉邦引进一种高铁珍珠粟品种，珍珠粟是那里最重要的主要作物之一。设计/方法/方法-选择实验用于调查农民对珍珠粟的各种生产和消费属性的偏好和权衡。所研究的珍珠粟的主要属性包括珍珠粟成熟所需的时间、谷物产生的面包的颜色、高铁含量（营养属性）的存在以及珍珠粟种子的价格。精选数据来自马哈拉施特拉邦三个有目的地选择的地区的630个珍珠米生产家庭。利用潜在类别模型研究农民对珍珠粟属性偏好的异质性，并分析农民选择高铁珍珠粟品种的可能性。研究结果-结果表明，样本中有三个不同的部分，农民的偏好在这些部分之间存在显著的异质性。高铁珍珠粟最受大户家庭的重视，这些大户主要生产供家庭消费，目前饮食质量较低。另一方面，主要为市场销售而生产的家庭从颜色和营养等消费特征中获得的收益较低。研究限制/启示-研究的主要限制是，它使用了一种陈述的偏好选择实验方法，这受到假设偏差的影响。在实施本研究时，生物强化高铁珍珠谷子品种尚未开发，因此作者无法使用真实产品和付款实施揭示偏好诱导方法。原创性/价值-所使用的方法（陈述偏好选择实验法）通常用于评估非市场商品，如环境商品和尚未进入市场的产品。它在农业和发展中国家的应用正在增加。据作者所知，这是调查农民/消费者对生物强化作物偏好的首选实验。该研究为开发和交付减少微量营养素缺乏的生物强化作物提供了有价值的信息。
Purpose - The purpose of this paper is to explore farmer acceptance of a biofortified staple food crop in a developing country prior to its commercialization. The paper focuses on the hypothetical introduction of a high-iron pearl millet variety in Maharashtra, India, where pearl millet is among the most important staple crops.Design/methodology/approach - A choice experiment is used to investigate farmer preferences for and trade-offs among various production and consumption attributes of pearl millet. The key pearl millet attributes studied include days it takes pearl millet to mature, color of the roti (flat bread) the grain produces, the presence of high-iron content (nutritional attribute), and the price of the pearl millet seed. Choice data come from 630 pearl millet-producing households from three purposefully selected districts of Maharashtra. A latent class model is used to investigate the heterogeneity in farmers' preferences for pearl millet attributes and to profile farmers who are more or less likely to choose high-iron varieties of pearl millet.Findings - The results reveal that there are three distinct segments in the sample, and there is significant heterogeneity in farmer preferences across these segments. High-iron pearl millet is valued the most by larger households that produce mainly for household consumption and currently have lower quality diets. Households that mainly produce for market sales, on the other hand, derive lower benefits from consumption characteristics such as color and nutrition.Research limitations/implications - The main limitation of the study is that it uses a stated preference choice experiment method, which suffers from hypothetical bias. At the time of implementing this study biofortified high-iron pearl millet varieties were not yet developed, therefore the authors could not have implemented revealed preference elicitation methods with real products and payment.Originality/value - The method used (stated preference choice experiment method) is commonly used to value non-market goods such as environmental goods and products that are not yet in the market. It's application to agriculture and in developing countries is increasing. As far as the authors know this is the first choice experiment implemented to investigate farmer/consumer preferences for biofortified crops. The study presents valuable information for development and delivery of biofortified crops for reducing micronutrient deficiencies.
