Summary: 'KLEOE05526' differs from the reference varieties, 'Oste Yel' and 'Osyel' mainly in leaf length, depth of incisions of the leaf margins, ray floret colour on the upper and lower sides and disc colour before dehiscence. The leaves of 'KLEOE05526' are medium to long whereas they are short to medium in length in 'Oste Yel' and long in 'Osyel'. The incisions of the margins of 'KLEOE05526' are very deep whereas they are deep in 'Oste Yel' and medium to deep in 'Osyel'. The main colour of the ray florets of 'KLEOE05526' are light yellow with yellow at the apex, whereas they are yellow with darker yellow at the apex and stripes on 'Oste Yel' and white yellow, with yellow at the apex margins on 'Osyel'. Before dehiscence, the disc of 'KLEOE05526' is dark grey green (yellow at the base) whereas it is yellow in both reference varieties.

PLANT: erect shoots with strong anthocyanin, medium height

LEAF: medium to long, wide, obovate shape, very deep incisions of margins, no variegation, medium green on the upper side

FLOWER: short to medium length peduncle, one or two complete ray floret whorls, medium inflorescence diameter
RAY FLORET: medium in length, medium width, obovate in shape, with an acute-dentate apex, inward rolling of longitudinal margins absent, slight reflexing, horizontal-upwards attitude, light yellow with yellow apex on the upper side, red-brown with some yellow along margins on lower side
DISC: dark grey green (yellow at base) before dehiscence.

Origin & Breeding History: 'KLEOE05526' was developed by Nils Klemm in Stuttgart, Germany, originating from an open pollination between an unnamed proprietary seedling and an unknown male parent conducted in June, 2002. In May, 2003, 500 seedlings were selected based on flower colour, growth habit and leaf colour. In April, 2004, one seedling was selected, named 'KLEOE05526' and was evaluated in greenhouse trials from 2004-05 for branching, flowering time, flower colour, growth habit and leaf colour.

Tests & Trials: The trials for 'KLEOE05526' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario, during the spring of 2007. The trials included 15 plants of each variety grown from rooted cuttings and transplanted into 11 cm pots. Observations and measurements were taken from 10 plants of each variety. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart.
