Variety used for comparison: 'Surf'

Summary: The flower heads of 'Yovail' have a smaller diameter than those of 'Surf'. 'Yovail' has shorter ray florets and narrower corolla tubes than 'Surf'. The ray florets of 'Yovail' are concave in cross section while those of 'Surf' are convex.


PLANT: year round cultivation for pot production, pinched type, spray flowering type, 8 week response group
STEM: green

FLOWER HEAD: double decorative type, self coloured, white colour group, very light intensity of colour, dense ray florets
RAY FLORET: ligulate with incurved inner florets, mostly straight longitudinal axis of majority, concave in cross section, emarginate and mamillate tips, white on upper and lower side

Origin & Breeding History: 'Yovail' originated from a cross pollination made in November 1999 in Salinas, California, United States, between the female parent 'Yohamilton' and the male parent an unidentified Chrysanthemum seedling selection 'YB-6675 '. The new variety was the product of a planned breeding program conducted by the breeder, Mrs. Wendy Bergman. 'Yovail' was discovered and selected by the breeder as a single flowering plant in November 2000. Selection of 'Yovail' was based on plant growth habit, inflorescence form, floret colours, response time, suitability for production and postproduction longevity. Asexual reproduction of the variety by vegetative tip cuttings was first conducted in Fort Myers, Florida, United States in March 2001.

Tests & Trials: Trials for 'Yovail' were conducted in Leamington, Ontario, in the fall of 2008. Flowering trials were performed under greenhouse conditions similar to those used in commercial chrysanthemum production. Forty unrooted cuttings of both the candidate and reference varieties were directly stuck into 15 cm pots, with 4 cuttings per pot, 10 pots per variety, planted August 25, 2008. Plants were spaced 30 cm apart and pinched once prior to short day treatment. All plants had the center bud removed. Observations and measurements were taken from 10 plants of each variety on November 3, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
