Genetic Diversity Analysis of Five Different Species of Riccia

Five species of the Riccia genus have been investigated by Rapid Amplified Polymorphic DNA (RAPD) analysis. The is explained and demonstrated with its genetic diversity based on morphological variations. Samples were collected from different parts University Dhaka growing in habitats around campus area. After study morphology, it has observed that population this taxon shows significant variation plant size, shape, colour, ventral scales, appendages rhizoids, position male female receptacles, etc. RAPD marker system was employed to estimate within between populations such Approximately 82% variations genotypes as revealed both phenotypic genotypic data. markers are being used increasingly analyse phylogenetic relationship among liverworts give exact framework taxonomic identification naturally occurring liverwort Riccia.
