Morphological Variability of Cola acuminata ((Pal. De Beauv) Schott and Endl.) Germplasm in Cameroon
Pierre Effa Onomo, Nicolas Niemenak and Denis Omokolo Ndoumou

Abstract: Seventeen accessions of Cameroonian Cola acuminata germplasm were evaluated to examine the variation based on 17 morphological traits in order to establish a list of minimum descriptors for characterization, to determine morphotypes and formation of core collection. By using the statistical software package SPAD 4.1 and SPSS 10.1 for Windows, Principal Component Analysis (PCA), Multiple Component Analysis (MCA) and Hierarchical Classification Ascendant (HCA) were carried out. All the descriptors studied have been included in the list of minimum descriptors for Cola acuminata. According to these descriptors, accessions can be distinguished in two morphotypes when the two phases of growth are taking into account. Makenene and Nkoteng accessions displayed the better growth whereas Mbang and Ngoulmakong displayed the weakest growth. These results of the Cameroonian accessions of Cola acuminata germplasm, could be utilised in breeding programmes after further evaluation and characterisation.
