6 primers produced amplification and produce a total of 212 amplicons across 73 genotypes of which 62 amplicons were found to be polymorphic with the level of polymorphism of 29.2%
The amplicons size with ISSR primers varies from 0.8 to 0.2 kb. The primers varied in the number of bands produced which ranged from 6 in ISSR 15 to 2 in ISSR 7 with an average of 4.17 bands per primer. Range of polymorphic bands per primer was 6 in ISSR 15 to 1 in ISSR 7
Dendrogram generated by UPGMA (Figure 2) differentiated all the 73 genotypes at 37% similarity
Dendrogram could be divided into three clusters namely cluster A, Cluster B and Cluster C. Cluster A had 70 genotypes at 58% similarity.Cluster B had only one genotype. Cluster C had Ac. 14 and Ac.16 at 43% similarity. Cluster A, subgrouped into four sub-clusters namely sub-cluster I, II, III and IV at 64% similarity. Sub cluster I had 19 genotypes and most were collected from South Andaman while sub cluster II composed 17 genotypes and represented the collections from NeilIsland
