Assessment of genetic diversity in Calamus thwaitesii BECC. (Arecaceae) using RAPD markers
چکیده انگلیسی

Calamus thwaitesii Becc. is a potentially useful rattan found in the Western Ghats of India and Sri Lanka. The wild stock of this rattan species is greatly diminished due to overexploitation for the furniture industry and increasingly rare. Genetic diversity was estimated in 80 samples representing eight populations from the Western Ghats and Sri Lanka using Random Amplified Polymorphic DNA (RAPD) markers. RAPDs generated a total of 120 markers with 10 decamer primers, of which 85% were found to be polymorphic. The percentage of polymorphic loci varied from 40.00 to 60.83 and genetic distance between populations ranged from 0.0332 to 0.2777. Among the analysed populations, Goa was found to be genetically superior followed by Achenkovil, Sinharaja and Talakkaveri. Majority of the genetic diversity was distributed within populations (70.79%) and only (29.21%) among populations. Genetic relationships estimated by the unweighted pair-group method with arithmetic averaging (UPGMA) cluster analysis and principal co-ordinate analysis failed to separate Indian and Sri Lankan populations geographically into two distinct groups.
