- The grass breeding industry is interested in a fast and cheap method of identifying contamination in seeds of Italian and perennial ryegrass (Lolium perenne L. and L. multiflorum Lam., respectively). This study shows that high-resolution melting curve analysis in combination with an unlabelled probe assay is an effective method of detecting single nucleotide polymorphisms (SNPs) in diverse Italian and perennial ryegrass backgrounds. This method proved efficient in differentiating ryegrass species and reducing the effect of additional DNA sequence polymorphisms close to the target SNP on the melting curve profiles. For the identification of contamination in Italian and perennial ryegrass seed production, high-resolution melting curve analysis shows great potential, as it is a single closed-tube PCR reaction with an easy workflow, providing results in <2h after DNA extraction.
