摘要:variability in these species by stable DNA markers will help in explaining the wi de distribution of individuals, Spalding et al. ( 1997 ); L akshmi et al. ( 2002). DNA sequence divergence provides an index to evolutionary relationships and genetic distance can be measured by variety of direct and indirect approaches. Molecular markers like Random Amplified Polymorphic DNA (RAPD) and Amplified Fr agment Length Polymorphism (AFLP) have been extensively used to quantify accurately the inter and intra - specific variabi lity in different plant groups, Chalmers et al. ( 1994 ) ; Lin et al. ( 1996 ) ; Russell et al. ( 1997), as these molecular markers are not inf luenced by the external environment, unlike the morphological markers. The application of these molecular markers to study the genetic relationship between and among some mangrove species has be en reported by few researchers, Lakshmi et al. ( 1997 , 2000, 20 02 ) ; Parani et al. ( 1997a, 1997b, 1998 ) ; Mukherj ee et al. ( 2004 ) ; Sahoo et al. ( 2007 ); Smita et al. ( 2009
