Mapping spatial distribution of genetic resources of kola ( Cola nitida (Vent.) Schott & Endl.) in Ghana and collection of germplasm for conservation, characterization and development of improved varieties

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