Genetic uniformity was assessed among sweetpotato (Ipomoea batatas ) clones propagated through adventitious and nodal procedures. A single sprout each of \u27Jewel.\u27 \u27Sumor,\u27 and L87-95 was used as source of clonal plants that were simultaneously propagated through conventional adventitious procedures and a tissue culture-based nodal culture technique. A sample of 15 decamer primers generated 64 scorable amplified fragments in a PCR-based assay. 29 of which were putatively polymorphic across n = 60 samples ( 10 each of nodal and adventitiously derived plants/genotype). Within adventitiously derived materials, putative polymorphisms ranged from 4.7 \u3c7r to\u3e3U\u3c£ depending on the genotypic class. In contrast, putative polymorphisms ranged from 0.0\u3c£ to 3.1 **• among nodally derived samples. Marker loci differen-tiated genotypes as well as putative marker phenotype variants through a multidimensional scaling analysis of the genetic similarity matrix. An \u27analysts of molecular variance\u27 shows that genotypic effects accounted for 88.7°«• of the total molecular marker variability, w hue propagation effects ( within genotypic groups I accounted for 1U4T. Results confirm that clonal plants derived from preexisting meristematic regions arc more genetically uniform than plants propagated from adventitious origins
