Abstract: |
Large Cardamom (Amomum subulatum Roxb.) is a major cash generating spice crop of Nepal, mainly confined to the eastern hills of Nepal. Fourteen large cardamom samples collected from Taplejung, Panchthar and Jlam Districts of Nepal during 2012 were used to evaluate genetic diversity using RAPD markers. Total of fifty one decamer primers (Operon series) were initially used for the experiment but only eighteen primers were selected based on nature of polym01phic and reproducibility for the analysis. Out of 133 loci generated 97.74 % were found to be polymorphic with number of alleles 1.977±0.013 and number of effective alleles1.409±0.024. Considering a single population Nei 's genetic diversity over all loci generated was found to be 0.263±0. OJ 2 with Shannon's information· index 0.416. On UPGMA clustering, two main clusters were obse1,ed that clearly separate wild cultivars (Churumpha) from commercially grown cultivars. The RAPD markers showed sufficient polymorphism for genotype discrimination and experimental reproducibility. Incorporation of molecular approaches over conventional method of genetic diversity assessment is. very much effective in pinpointing the potential genetic diversity for cardamom improvement. |
