Forty seven Morocco carob populations from different sites were studied to assess their genetic variation
based on pods and kernels measures. The mean of the main descriptive morphological values of pods
were length (13.85 cm), width (1.57 cm), central thickness (0.64 cm), number of viable kernels (12.26),
yield (kg pods / tree) ( 113.46 Kg), pulp weight (5.91g), kernels weight (1.76 g), kernel length (0.72 cm)
kernel width (0.39 cm), kernel thickness (0.39 cm) and kernel yield (23.12%). Most of the parameters
measured showed significant difference (P < 0.05 to P < 0.001) that indicates a high genetic diversity;
type and geographical origin of trees being taken as the source of variation. We recorded more than 60%
germination after just 4 days of incubation and 100% germination after 8 days for the chemical agent.
However, for water boiling, we chose a germination rate of less than 50% and 95% germination after
eight days of incubation.
The relationship among these characters was analysed hierarchical clustering resulting in the separation
of these populations classed in three grouped and three ungrouped populations.
