Abstract: Kaempferia galanga   is an important medicinal herb used in many ayurvedic drug preparations.We investigated the genetic diversity and structure of 4 populations of K. galanga collected from South 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.
