The genetic diversity among 30 accessions of Elytrigia repens (L.) Nevski was analyzed using 100 intersimple sequence repeat (ISSR) primers, 12 of which generated distinct amplification products. Out of the 132 repeatable bands detected, 100 bands were polymorphic. The percentage of polymorphic bands was 70.66%, with a mean of 8.33 percentage of polymorphic bands per primer. The ISSR-based genetic similarity coefficients among the 30 accessions ranged from 0.509 to 0.873, revealing high genetic diversity. The 30 E. repens accessions were divided into eight groups based on an unweighted pair-group method with arithmetic mean cluster analysis and a principal components analysis. We found that genetic distance is correlated with geographical distance among the 30 E. repens accessions studied (r = 0.812, p < 0.05) using Mantel's test. Our results confirm the potential value of genetic diversity preservation for future breeding programs.Résumé : Les auteurs ont analysé la diversité génétique au sein de 30 accessions de l'Elytrigia repens (L.) Nevski en utilisant des amorces à séquences répétitives intersimples (ASRI), dont 12 ont généré des produits d'amplification distincts. Parmi les 132 bandes répétitives détectées, 100 bandes se sont révélées polymorphiques. On a obtenu un pourcentage de bandes polymorphiques de 70,66 %, avec une moyenne de 8,33 pourcentage de bandes polymorphiques par amorce. Les coefficients de similitude génétique basés sur les ASRI parmi les 30 accessions se rangent de 0,509 à 0,873, révélant une forte diversité génétique. Les 30 accessions de l'E. repens se divisent en huit groupes basés sur une méthode groupe-paire non pondéré avec moyenne arithmétique, analyses par regroupement et analyse en composantes principales. Les auteurs ont obtenu une corrélation entre la distance génétique et la distance géographique parmi les 30 accessions de l'E. repens étudiées (r = 0,812, p < 0,05), en utilisant le test de Mantel. Les résultats confirment la valeur potentielle de la conservation de la diversité génétique pour de futurs programmes de croisements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
