Molecular genetic fingerprints of eleven Hedychium species from
Northeast India were developed using PCR based markers. Fifteen
inter-simple sequence repeats (ISSRs) and five amplified fragment
length polymorphism (AFLP) primers produced 547 polymorphic
fragments. Positive correlation (r = 0.46) was observed between the
mean genetic similarity and genetic diversity parameters at the
inter-species level. AFLP and ISSR markers were able to group the
species according to its altitude and intensity of flower aroma.
Cophenetic correlation coefficients between the dendrogram and the
original similarity matrix were significant for ISSR (r = 0.89)
compared to AFLP (r = 0.83) markers. This genetic characterization
of Hedychium from Northeast India contributes to the knowledge of
genetic structure of the species and can be used to define strategies
for their conservation and management.
