Abstract Kaempferiagalangais animportantmedicinal herb used in many ayurvedic drug preparations.We investigated the genetic diversity and structureof 4 populations ofK.galangacollected fromSouth India using Inter-Simple Sequence Repeat (ISSR) markers. A low level genetic diversity was noticed among the populations (PPB= 44.45%; h= 0.1517 and I= 0.2309). Average diversity within population was also low (PPB= 23.29%; h= 0.1003; I= 0.1439) and the highest genetic diversity was observed in Shimoga population (PPB= 27.27%; h= 0.112; I=0.1625). Nei’s differentiation coefficients (GST) was found to be high (0.3942) and the gene flow (Nm) was low (0.7683), confirming the high population genetic differentiation.The unweighted pair-group method using arithmetic average (UPGMA) clustering demonstrated similar results. Based on the overall low genetic diversity and high genetic differentiation among K.galanga populations in South India, a conservation strategy is proposed. Not Available |
