Origin & Breeding History: 'NPCW05102' originated from a cross pollination made in Stuttgart, Germany, between the variety 'Winter Rose' and the proprietary seedling K95. Seedlings were selected in the summer of 2001 for criteria based on bract size, bract colour, bract shape, leaf quality and branching characteristics. The selected seedling was grafted in 2002 to promote branching and further evaluated for plant vigour and postharvest characteristics in Stuttgart, Germany.
Tests & Trials: The detailed description of 'NPCW05102' is based on the UPOV Report of Technical Examination, application number 2006/0142, purchased from the Community Plant Variety Office, Angers, France. The trials were conducted by the University of Aarhus in Aarslev, Denmark in 2007. Colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
