This study investigates the genetic diversity and qualitative characteristics of 29 <em>Withania somnifera</em> L. genotypes, using RAPD markers to guide breeding strategies. Plant components from several Indian locations were grown in a randomized block design. Genomic DNA was isolated using a modified C-TAB technique and analyzed with 33 RAPD markers, revealing high variability (PIC values ranging from 0.154 to 0.985).

Genetic analysis revealed substantial polymorphism, with a UPGMA dendrogram clustering the genotypes into eight distinct groups, indicating diverse genetic backgrounds. The qualitative and molecular characterization of genetic variation in ashwagandha sheds light on the variability and adaptability of this essential therapeutic plant. Understanding and utilizing this variability allows researchers and breeders to improve the conservation, breeding, and long-term usage of ashwagandha, assuring its continued value in traditional medicine and modern pharmacology.

The study was designed to assess the genetic diversity of 64 tef genotypes utilizing 10 Simple Sequence Repeats (SSRs) markers. This investigation took place at the Agricultural Biotechnology Research Center in Holeta, Ethiopia. Field phenotypic diversity evaluation was conducted at two distinct locations: Debre Zeit and Worabe, applied a simple lattice design during 2020/21 season. Molecular analysis of variance demonstrated a substantial proportion of variation among individuals (46 %), followed closely variation among individuals (43 %), with the least variation observed within population (11 %). Concurrently, analysis of morphological data, encompassing twenty phenotypic characteristics, revealed significant variation (P ≤ 0.01) among almost all the tested genotypes for recorded parameters, as indicated by combined analysis of variance across sites. These findings underscore the high diversity among the studied genotypes, suggesting a considerable potential for crop improvement through direct selection and intra-specific hybridization strategies.
