Abstract excerpt
BACKGROUND: Leymus chinensis (sheepgrass) is a key perennial forage grass for grassland restoration in northern China, but its complex genome and high genetic diversity hinder precise cultivar identification using traditional morphological methods. Recent advances in SNP-based molecular markers provide efficient and reliable tools for Distinctness, Uniformity and Stability (DUS) testing and cultivar-rights...
