An initial exploration of core collection construction and DNA fingerprinting in Elymus sibiricus L. using SNP markers

Summary

<i>Elymus sibiricus</i> L., an excellent forage and ecological restoration grass, plays a key role in grassland ecological construction and the sustainable development of animal husbandry. In China, the wild germplasm resources of <i>E. sibiricus</i> are abundant, and they are shaped by similar and contrasting climatic conditions to form distinct populations, which enrich the genetic diversity of <i>E. sibiricus</i>. To more comprehensively aggregate <i>E. sibiricus</i> germplasm resources at a lower cost and to more accurately utilize its genetic variation, this study conducted a preliminary exploration of core germplasm collections and fingerprinting of <i>E. sibiricus</i> using single nucleotide polymorphism (SNP) markers. By combining multiple evaluation measures with weighted processi
