Valuation of farmer knowledge has been seen as a route to promote sustainable use of plant genetic resources. In pineapple production systems in Benin, inadequate knowledge of cultivation practices can lead to a number of inconveniences including abandon of some varieties and cultivars. To understand how farmer's knowledge and cultivation practices impact the sustainable utilization of pineapple genetic resources, we surveyed 177 pineapple farmers in southern Benin. We assessed farmers' knowledge and analyzed the relationship between their knowledge and factors such as age, education, and locality of provenance. Pineapple production system was dominated by men (96% respondents). According to farmers, Smooth cayenne is international market-oriented while Sugarloaf mainly targets domestic and regional markets. All farmers recognized that Smooth cayenne provided more income (USD 5,750/ha) than sugarloaf (USD 3,950/ha) in the production systems of southern Benin. The high value of median scores in comparison with the range of possible score showed that most farmers agreed and shared relatively similar knowledge. Correlation matrix and multiple linear regressions showed a significant relationship between farmers' practices and their knowledge of the plant; their knowledge of pineapple varieties is based on fruits traits. Also, farmer's knowledge was associated with locality of provenance. Constraints and options for genetic resources conservation and utilization in the pineapple production systems in Southern Benin were discussed based on current knowledge.
农民知识的评估被视为促进植物遗传资源可持续利用的一条途径。在贝宁的菠萝生产系统中，对种植实践的了解不足会导致诸多不便，包括一些品种和栽培变种被弃用。为了解农民知识和种植实践如何影响菠萝遗传资源的可持续利用，我们对贝宁南部的177名菠萝种植农户进行了调查。我们评估了农民的知识，并分析了他们的知识与年龄、教育程度和产地等因素之间的关系。菠萝生产系统以男性为主（96%的受访者）。据农民称，“平滑卡宴”面向国际市场，而“砂糖面包”主要针对国内和区域市场。所有农民都认识到，在贝宁南部的生产系统中，“平滑卡宴”的收入（5750美元/公顷）高于“砂糖面包”（3950美元/公顷）。与可能得分范围相比，中位数得分较高表明大多数农民意见一致且拥有相对相似的知识。相关矩阵和多元线性回归表明，农民的实践与他们对这种植物的知识之间存在显著关系；他们对菠萝品种的了解基于果实特征。此外，农民的知识与产地有关。基于现有知识，讨论了贝宁南部菠萝生产系统中遗传资源保护和利用的制约因素及选择。
