Variety Description

Varieties used for comparison: 'Fishelus' (Schoene Helena '06) and 'Zonalisalo' (Fidelity L Light Salmon)

Summary: 'Zosa' differs from the reference varieties, 'Fishelus' and 'Zonalisalo', mainly in conspicuousness of the zone on the upper side of the leaf, conspicuousness and colour of upper petal markings, size of the white zone at the base of the upper petal and colour of the middle third of the pedicel. The zone on the upper side of the leaf of 'Zosa' is medium to strong in conspicuousness whereas it is weak to medium on the leaves of 'Fishelus' (strong on new leaves). The upper petal markings of 'Zosa' are weak to medium in conspicuousness whereas they are weak in 'Fishelus' and very weak in 'Zonalisalo'. The petal markings are darker red in 'Zosa' than they are in both reference varieties. The zone at the base of the upper petal of 'Zosa' is medium in size whereas it is very small in 'Zonalisalo'. The middle third of the pedicel of 'Zosa' is green to light red whereas it is medium red in 'Fishelus' and green in 'Zonalisalo'.

Origin & Breeding History: 'Zosa' originated from a controlled pollination made in Enkhuizen, The Netherlands in 2000. The female parent, identified as J2218-2 was crossed by the male parent, identified as H2167-2. A single seedling was selected in April 2001 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 'Zosa' 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.
