AB  - Indo-Burmese region was the primary center of eggplant diversity from where the crop extended to several
secondary origins of diversity. In this study, the genetic diversity among fifty-six eggplant accessions collected from
three countries was assessed using sixteen polymorphic SSR markers to determine suitable parents for heterotic
hybridization. The estimation of genetic diversity among the population of three countries (Bangladesh, Malaysia, and
Thailand) varied from 0.57 to 0.74, with Shannon’s index value of 0.65. The mean value of expected heterozygosity
and Nei’s index was 0.49, with an average PIC value of 0.83. A dendrogram was constructed based on UPGMA
(unweighted pair group method with arithmetic mean), and the dendrogram categorized all accessions into six
groups. The AMOVA (analysis of molecular variance) revealed a 77% total variation within the population from three
different countries and 23% total variation among the populations. The result revealed a high genetic differentiation
among the eggplant germplasms while the accessions that are farther from each other show a high level of diversity;
thus, they can be recommended as parental in breeding programs. Hence, accessions, EB12, ET11, ET13, ET15, ET16,
and ET17 could be crossed with accessions EM3, EB34, and EB3 for improvement in the future breeding program.
