Description:
Plants collected from old turfs in Maryland, Pennsylvania, New York, and New Jersey were the original source of most of the parental germplasm. However, plants selected from Elka, a cultivar of European origin, were used as the maternal parents of 35 of the parental clones of Prelude. The remaining parental clones were selected from a population of 2580 tillers chosen from the best of 2500 turf plots.
