Variety Description

Varieties used for comparison: 'Glacis' (Patriot White) and 'Fisroweiss' (Rocky Mountain White '06)

Summary: 'Zonawite' differs from the reference varieties, 'Glacis' and 'Fisroweiss' mainly in plant size, waviness of the leaf margin and inflorescence diameter. The plants of 'Zonawite' are shorter and narrower than both reference varieties. The leaf margin of 'Zonawite' has medium waviness whereas it is weak in both reference varieties. The inflorescence diameter of 'Zonawite' is smaller than both reference varieties.

Origin & Breeding History: 'Zonawite' originated from a controlled pollination made in Enkhuizen, The Netherlands in 2001. The female parent, identified as number 250 was crossed by a mixture of pollen from several selected male plants. A single seedling was selected in April 2002 and propagated by cuttings. The new pelargonium was tested one year later at greenhouse and field performance trials in Enkhuizen, The Netherlands and evaluated for criteria including earliness, good branching, good and stable flower colour, flower size, rich and continuous flowering and resistance against Botrytis. In the same year it was tested in Sarrians, Southern France for heat resistance and resistance to drought stress.

Tests & Trials: Trials for 'Zonawite' were conducted in a polyhouse during the summer of 2006 at St. Thomas, Ontario. The trial included 15 plants of the candidate and reference varieties. Rooted cuttings were planted into 10 cm pots on May 1, 2006 and then transplanted into 20 cm pots on June 26, 2006. Measured characteristics were based on 10 measurements. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
