Origin & Breeding History: 'RIJN200023' is the product of a breeding program conducted in De Lier, The Netherlands whose objective was to create and develop new compact, freely clumping and flowering Anthurium cultivars with strong roots, dark green leaves, attractive spathe colours and good inflorescence longevity. 'RIJN200023' originated from a cross made in October 1998 between proprietary selections of Anthurium andreanum; '9821' as the female parent and '9613' as the male parent. 'RIJN200023' was selected in July 2000 from the resulting progeny growing in a controlled environment in De Lier, The Netherlands. The selection criteria included plant shape, hard leaves and large, bright red spathes.
Tests & Trials: The detailed description of 'RIJN200023' is based on the UPOV report of Technical Examination, CPVO reference number 2004/0984, grant number 18413. The trials were conducted by Stichting DLO, WOT-unit, CGN-Plantenrassenonderzoek in Wageningen, The Netherlands in 2005. Colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
