The ImprovLoliumCol Activity was completed with the publication of the Activity report.
This Activity followed up on the work of the FACCE-JPI ERA-NET+ project GrassLandscape, in which 427 accessions from the natural diversity of perennial ryegrass and nine accessions from related taxa were genotyped, phenotyped and documented for the environment of their collection sites. The ImprovLoliumCol activity promoted the inclusion of as many as possible of the accessions used in GrassLandscape into EURISCO and to be flagged as AEGIS and was concluded with 435 accessions registered in EURISCO and 344 expected to be flagged as part of AEGIS. Phenotypic data recorded in the frame of GrassLandscape were made easily available as C&E data via an ECPGR European Forage Portal connected to the EURISCO database. Using new knowledge on the spatial and environmental distribution of the natural diversity of perennial ryegrass provided by GrassLandscape, two levels of core collection were set up, a small one and a large one, including 159 and 211 accessions, respectively. These two levels of core collections were flagged on the forage crop portal.
