Abstract:
Identification and characterization of germ plasma is an important link between the conservation
and utilization of plant genetic resources. In the present research, we identified and characterized
genetic and phenotypic variations within a hundreds cultivars from Riau. The objective of this
research were to investigate genetic variability of local Mangoes in Riau. This research was used a
survey method where carried out in 12 regency in Riau Province. The result found many variations
of six species of mangoes, there are M. foetida, M. indica, M. odorata, M. sumatrana, M. laurina,
and two other species which is the new records. The infraspecies level of diversity showed that M.
odorata and M. foetida has a high variability of the fruit shapes. This investigation will help
breeders of mangoes for the improvement programs
