Assessment of genetic diversity of Curcuma aromatica from eastern India using ISSR and RAPD markers

Application of Inter Simple Sequence Repeats and Random Amplified Polymorphic DNA markers in Curcuma aromatica collected from 4 different populations of Odisha. A dendrogram was constructed through sequential agglomerative hierarchial and nested (SAHN) clustering and unweighted pair group method with arithmetic mean (UPGMA) analysis using Jaccard’s similarity coefficient of combined markers using this particular species. Two major clusters were found i.e., cluster-I (Koraput-1, Koraput-2, Koraput-3, G.Udaigiri-1, G.Udaigiri-2, G.Udaigiri-3 and Phulabani-1, Phulabani-2, Phulabani-3) and cluster-II (Raikia-1, Raikia-2 and Raikia-3). The clustering pattern also revealed moreover the extent of genetic similarity between germplasms collected from those populations. This technique would be further utilized for identification and tagging of important novel gene present in different taxa or improvement work in family Zingiberaceae. This study would be of immense significance for conservation and characterization of important medicinal plant species.
