It is very important to characterize the available cotton germplasm aiming to identify novel genetic and genomic resources that can be used for future cotton breeding. Keeping this in view, a total of 179 cotton genotypes were characterized with the inter-primer binding site (iPBS) retrotransposon marker system. Seven iPBSretrotransposon primers yielded a total of 134 scoreable bands and among these, 128 bands were polymorphic. The mean polymorphic bands per primer were 18.28, with values ranging between 16 and 21. The mean polymorphism rate of 7 iPBS retrotransposon primers was calculated as 96.28%. The polymorphism information content value varied between 0.31 and 0.46 with an average of 0.395. Genetic similarity was calculated using the POPGENE software and values ranged between 0.320 and 0.955. Population structure and neighbor-joining analysis divided the evaluated germplasm into two populations. The analysis of molecular variance revealed that maximum variations (96%) are due to differences within the populations. The information presented here has comprehensively demonstrated the potential of iPBSretrotransposon markers in detecting genetic diversity and phylogenetic association analyses of cotton. This knowledge will be helpful for future cotton breeding.eninfo:eu-repo/semantics/openAccessCotton (Gossypium hirsutum L.) center dotMolecular markers center dot Molecular characterization center dotPhylogenetic analysis center dot Retrotransposons center dot iPBSArticle7151737174810.1007/s10722-023-01726-12-s2.0-85171356796Q2WOS:001069249700001Q2
