Morphological and Genotypic Characterization Of Different Lotus (Nelumbo Nucifera Gaertn.) Samples Available in Bangladesh

Asian lotus (Nelumbo nucifera Gaertn.), commonly known as sacred is a basal eudicot. It has been grown and cultivated food, medicine for cultural, religious activities. In the current study, samples were collected from six different locations to evaluate variation among germplasm based on external morphological characteristics, well as, study genetic molecular characterization. Analysis of variance showed higher level variations all features. Based features, dendrogram was constructed assess linkage germplasm. The yellow Cumilla considered superior studied. To diversity correct identification germplasm, method “Barcoding” performed. achieve goal, two plastidial regions: rpoB rpoC1 employed. showing successful PCR subjected sequence analysis their barcode genes. All selected genes N. in multilocus sequences except Rajshahi also confirmed yellowish new cultivar ‘Gomoti’, newly found Bangladesh. Genetic obtained context DNA barcoding had used create phylogenetic tree which clustered into five main clades. establishing an efficient protocol capable elite gene source. Moreover, future studies are warranted see identifying capability diverging power barcodes. Bangladesh J. Plant Taxon. 29(1): 85-95, 2022 (June)
