ABSTRACT
The diversity amongst Teminalia catappa population in two different locations in the Lagos area of South Western Nigeria was investigated. Forty trees were sampled for twenty eight quantitative and twelve qualitative characters. Variability was observed in qualitative characters such as leaf shape and ripe fruit colour. Quantitative characters analyzed using multivariate statistical analysis showed high intraspecific variability for most of the characters determined. Cluster analysis using the unweighted pair group method using arithmetic mean (UPGMA) method revealed four main clusters which were not based on location of collection but on morphological characters. The trees were grouped into the main clusters based mainly on plant architecture. The result from the trees studied showed that selections based on traits such as fruit size, fruit colour and leaf sizes can be undertaken for future improvement or development of this tree crop in Nigeria.
