Understanding folk classification system of perceived variation and preferences in fruit traits are necessary to effectively engage farmers in the domestication of wild edible fruit tree species. Social attributes can help to better understand perception of variation, and preferences. We focused on Parkia biglobosa (Jacq.) Benth., a valuable fruit tree in Benin, examining the folk classification systems and preferences for fruit morphotypes, and the extent to which they are related to social attributes in the two major climatic zones of its occurrence in Benin. Using random sampling, we selected 648 informants for individual semi-structured interviews which focused on recognized morphotypes, local classification system, and both desirable and undesirable traits related to pod, pulp, and seeds. Data were analyzed using relative frequency of citation, and principal component analysis. Informants used similar criteria to differentiate fruits of species including pod shape (RFC = 100%), pulp yield (RFC = 100%) and number of seeds per pod (RFC = 99.84%), color (RFC = 100%) and taste (RFC = 99.84%) of pulp as well as brightness (RFC = 99.07%) and color (RFC = 100%) of seed. Informant’s preferences were marked for fruits containing large number of seeds with larger size and of good seed quality. Sweetness of the pulp was also mentioned, though some differences were noted among gender and sociolinguistic groups. Our findings provide essential information for decision-making for effective domestication initiatives. To advance further domestication, while conserving essential genetic resources, quantitative morphological and molecular characterization of the observed variations in P. biglobosa are needed.

贝宁对非洲刺槐豆[Parkia biglobosa(Jacq。)Benth。]果实性状的感知变化和偏好:对驯化的影响

要有效地使农民参与野生可食用果树物种的驯化,必须了解人们对水果性状的感知变异和偏好的民间分类系统。社会属性有助于更好地理解变异和偏好。我们专注于Parkia biglobosa(Jacq。)Benth。是贝宁的一种宝贵果树,研究了民间分类系统和水果形态类型的偏好,以及它们在贝宁发生的两个主要气候区中与社会属性的关联程度。通过随机抽样,我们选择了648名线人进行了半结构化访谈,重点关注公认的形态,局部分类系统以及与豆荚,果肉和种子相关的理想和不良特性。使用相对引用频率和主成分分析来分析数据。信息提供者使用相似的标准来区分不同种类的果实,包括豆荚形状(RFC = 100%),果肉产量(RFC = 100%)和每个豆荚的种子数(RFC = 99.84%),颜色(RFC = 100%)和味道(纸浆的RFC = 99.84%)以及白度(RFC = 99。07%)和种子的颜色(RFC = 100%)。告密者的喜好被标记为含有大量种子的种子,这些种子具有较大的尺寸和良好的种子质量。还提到了果肉的甜度,尽管在性别和社会语言群体之间发现了一些差异。我们的发现为有效驯化计划的决策提供了必要的信息。为了进一步驯化,在保留必要的遗传资源的同时,对所观察到的变异进行定量形态学和分子表征。我们的发现为有效驯化计划的决策提供了必要的信息。为了进一步驯化,在保留必要的遗传资源的同时,对所观察到的变异进行定量形态学和分子表征。我们的发现为有效驯化计划的决策提供了必要的信息。为了进一步驯化,在保留必要的遗传资源的同时,对所观察到的变异进行定量形态学和分子表征。需要P. biglobosa
