Ho Journal of Animal and Plant Sciences JAPS 20222022/01/07 32 1 78-83 1018-7081 https://doi.org/10.36899/JAPS.2022.1.0404 <p><em>Pseuderanthemum palatiferum</em>&nbsp;is a commonly used ornamental plant in Vietnam. It is getting more attention due to its medicinal values. In this study, the genetic composition of 16&nbsp;<em>P. palatiferum</em>&nbsp;accessions and relatives collected from Vietnam were analyzed using 16 RAPD and ISSR molecular markers. The obtained results show that both RAPD and ISSR produced a high number of polymorphic bands. The similarity coefficient varies among RAPD and ISSR, from 0.53 &ndash; 0.95 and 0.32 &ndash; 0.91, respectively. Mantel test also shows poor correlation between RAPD and ISSR markers. Both data from RAPD markers or combination of RAPD and ISSR markers could differentiate&nbsp;<em>P. palatiferum</em>&nbsp;from its relatives. The obtained results reveal the large variation in genetic composition of&nbsp;<em>P. palatiferum</em>&nbsp;population in Vietnam. The findings could be beneficial in classification, identification, and conservation efforts of&nbsp;<em>P. palatiferum</em>.</p> Genetic diversity, ISSR, molecular markers, Pseuderanthemum palatiferum, RAPD Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=AG-20-0048
