|Abstract: ||DNA profiling and molecular characterization has been increasingly used to validate and establish working germplasm collections and crop improvement programs. Eighteen accessions of jackfruit (Artocarpus heterophyllus Lam) maintained in the field gene bank, IIHR, Hessaraghatta were distinguished at the DNA level by ISSR analysis. Primers that generate accession specific profiles were identified and found useful for generating DNA profiles unique to the jackfruit accessions studied. The cluster diagram depicting genetic relationships between accessions showed that the accessions Gumless, Dorichandra and Tenvarike were the most divergent ones. This study revealed the ability of ISSR markers to detect polymorphism and also to evaluate genetic variability and differentiate accessions of jackfruit. The morphological characterization when collated with DNA profiles of these accessions showed that Tenvarike, which is a divergent accession had desirable fruit characters like low latex exudation and low flake fiber content. Thus molecular marker data together with morphological parameters could be effectively utilized for identifying trait specific germplasm to establish working collections in crop improvement programmes. Further studies are in progress to identify other unique traits viz., earliness, low core thickness, higher number of flakes per fruit, flake thickness, higher total soluble solids etc. integrating molecular analysis with morphological characterization data.|
