Variety Description

Varieties used for comparison: 'PKMP05', 'Moon' and 'Planet'

Summary: The plants of 'PKMP09' have dense branching while the plants of 'Moon' and 'Planet' have medium density branching. In profile, the sides of the corolla tube are slightly diverging towards the mouth for 'PKMP09' while the sides of the corolla tube of 'PKMP05' are parallel to slightly diverging. The outer side of the corolla tube of 'PKMP09' is violet while it is lighter violet for 'PKMP05'. In cross-section, the corolla lobe of 'PKMP09' is moderately convex at the mid-point whereas the corolla lobe of 'PKMP05' is weakly convex at the mid-point. The central furrow on the inner side of the corolla lobe of 'PKMP09' is strong while the central furrow is absent or weak for 'Moon' and weak for 'Planet'.

Origin & Breeding History: The variety 'PKMP09' originated from a cross between two unnamed proprietary selections, '08.03' and '08.05', at PKM Nurseries in Sohus, Demark in June 2007. The resulting seedlings were selected in 2008 based on plant habit and flower colour.

Tests & Trials: The detailed description of 'PKMP09' is based on the UPOV report of Technical Examination, application number 2010/1273, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted by the National Institute of Agricultural Botany in Cambridge, United Kingdom in 2011. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
