At the National Center for Plant Genetic Resources of Ukraine, a trait-specific collection of Phleum pratense was registered for yield (Certificate No. 309 dated October 27, 2021), and a trait-specific collection of Festuca arundinacea was registered for valuable economic traits (Certificate No. 349 dated October 23, 2025). The trait-specific collection of Phleum pratense includes one botanical species and comprises 37 accessions originating from two countries (Ukraine – 36 accessions, Lithuania – 1 accession). All accessions were evaluated based on 16 traits, assessed using 62 expression levels. The trait-specific collection of Festuca arundinacea consists of 62 accessions from three countries (Ukraine – 47 accessions, Lithuania – 14 accessions, Poland – 1 accession). These were evaluated for 19 traits using 53 expression levels. Product Description popup.authors popup.nrat_date 2025-12-23 Close
