Narrative
Compared to 'Aurora', 'Tetra' is equal in seedling vigor, establishment and recovery after cutting, about three days later and somewhat less winter hardy. Seed yield is 70% Aurorabut reduction may be partly due to cross-pollination with diploid plants (Bolton, J.L. Forage Notes 15(1):19). This accession may be a duplicate of PI 195482, 257273 and 297319 (Original NPGS Site Index Card).
