我们研究了影响哥伦比亚西南部考卡省217户家庭采用改良木薯品种的因素。利用单核苷酸多态(SNPs)DNA指纹技术，对不同品种的田间品种进行了鉴定。我们还利用这些信息消除了采用模式中可能存在的偏差，这些偏差可能是由于对改良品种(IV)的错误分类造成的。结果，我们发现，农民大大高估了他们对静脉输液的使用，并且农民自我识别和DNA指纹分析在决定采用的因素上存在重要差异。这一发现表明，将DNA指纹分析纳入四次收养研究对于确保未来农业经济研究的准确性和后续政策建议的相关性是重要的。
We examine factors affecting the adoption of improved cassava varieties of 217 households in the Cauca Department in southwest Colombia. Using DNA fingerprinting through Single Nucleotide Polymorphisms (SNPs), we identified different cultivars in farmers fields. We also used this information to remove possible bias in the adoption model that could have resulted from a misclassification of improved varieties (IVs). As a result, we found that farmers substantially overestimate their use of IVs and there are important differences in the determinants of adoption between farmer self-identification and DNA fingerprinting. This finding implies that the incorporation of DNA fingerprinting in IV adoption studies is important to ensure the accuracy of future agricultural economic research and the relevance of subsequent policy recommendations.
