Curcumin profiling and genetic diversity of different accessions of Curcuma longa L.

ObjectiveTo investigate the genetic diversity and variation in active compound of turmeric rhizomes collected from different niches of Uttarakhand.MethodsGenetic diversity and relationship of Curcuma longa accessions was evaluated by random amplification polymorphism DNA analysis and curcumin profiling was evaluated by high performance liquid chromatography method.ResultsThe curcumin contents in 20 accessions of turmeric rhizomes were found to be in the range of 0.90% to 3.26%. All accessions were separated into six groups (92% genetic similarity) by using 10 decamer oligonucleotide primers for the amplification of genomic DNA.ConclusionsThe results indicated the possibility of selecting high quality clones for large scale production.
