Identification and Discrimination of Ocimum basilicum L. Morphotypes

In order to assess morphological variability and to classify basil accessions into morphotypes, a total of 97 basil (Ocimum basilicum L.) accessions was characterized using 27 morphological traits. Cluster analysis based on phenotypic dissimilarity matrix yielded six clearly defined clusters representing distinct morphotypes: Lettuce-leaf, Small-leaf, True basil, Purple basil (A), Purple basil (B), and Purple basil (C). A Neighbour-net diagram based on the same dissimilarity matrix allowed the visualization of apparently conflicting data, such as caused by hybridization between phenotypically very different ancestors.
