Kola (Cola nitida (Vent.) Schott & Endl.) is a tree crop of great economic and socio-cultural importance. Available genetic resources of kola are increasingly vulnerable to genetic erosion due to decreased population sizes resulting from land use changes and cutting of trees for timber and firewood production. There is therefore an urgent need to conserve genetic resources of kola in Ghana. The objective of this research was to map distribution, ascertain status of collection and conservation of kola in Ghana and to collect germplasm from mapped provenances for characterization and breeding of improved varieties. Mapping of distribution of kola was carried out by undertaking trips to kola growing areas in Ghana. Transects were constructed and an inventory of C. nitida was carried out using GPS. The geo-references were interpolated into the map of Ghana using ArcGIS software. The spatial analysis showed Jasikan, Akaa, Ahamasu, Ampeyo, Pampawie, Oyoko, Akwadum, Jejeti, Atwedie, Kwahu, Asuom, Tweapease, Kade, Twifo Praso, Assin Fosu, Ntafrewaso, Hemang, Jamasi, Kona, Bipoa, Offinso, Akumadan and Aframcho as the areas with a dense natural populations of C. nitida. The current knowledge and understanding of distribution of kola resources provides opportunity to have a comprehensive collection of genetic resources of kola in Ghana. This aided in collection of 102 new accessions from 22 provenances in the Volta and Eastern regions of Ghana. This in addition to 226 earlier collections constitute 328 accessions of C. nitida in Ghana. The evaluation and understanding of diversity of these kola resources could offer yet-unknown traits of high economic value for further domestication and development of improved varieties.

科拉（可乐尼达（Vent。）Schott＆Endl。）是一种具有重要经济和社会文化意义的树木。由于土地用途的变化和砍伐树木以生产木材和薪柴，可口可乐的可用遗传资源越来越容易受到遗传侵蚀的影响，这是因为人口规模减少了。因此，迫切需要保护加纳可乐的遗传资源。这项研究的目的是绘制地图，确定加纳可乐的收集和保存状况，并从绘制的种源中收集种质，以鉴定和育种改良品种。通过前往加纳的可乐种植区进行了可乐分布图。构造了样条并编制了尼迪梭菌清单是使用GPS进行的 使用ArcGIS软件将地理参考插入到加纳的地图中。空间分析显示Jasikan，Akaa，Ahamasu，Ampeyo，Pampawie，Oyoko，Akwadum，Jejeti，Atwedie，Kwahu，Asuom，Tweapease，Kade，Twifo Praso，Assin Fosu，Ntafrewaso，Hemang，Jamaasi，Kona，Bipoa，Offinso，Akumadandan Aframcho为自然界中C. nitida的密集地区。目前对可乐资源分配的了解和理解为加纳全面收集可乐遗传资源提供了机会。这有助于从加纳的伏尔塔州和东部地区的22个种源中收集102个新种质。除226个较早的收藏外，它还构成328个nit。C. nitida在加纳。对这些可乐资源的多样性进行评估和了解可以为进一步驯化和改良品种的开发提供高经济价值的未知特性。
