Variety Description

Variety used for comparison: 'Yellow Cherie'

Summary: 'Yolisette' has a taller plant height than 'Yellow Cherie'. The leaves of 'Yolisette' are shorter in length and have converging to overlapping margins of sinus between lateral lobes while 'Yellow Cherie' has diverging margins. 'Yolisette' has a higher number of ray florets than 'Yellow Cherie'. 'Yolisette' has shorter ray florets which are straight along the longitudinal axis while the ray florets of 'Yellow Cherie' are incurving. 'Yolisette' differs slightly in ray floret colour from 'Yellow Cherie'.


'Yolisette' is a year round, pinched, spray pot chrysanthemum variety with an eight week response time. The stem has no anthocyanin colouration. The leaves have an acute shaped base and the margins of sinus between lateral lobes are converging to overlapping.

The flowers are a single daisy type and are yellow in colour. The outer ray florets are very narrow in width. The ray florets are straight along the longitudinal axis and flat in cross section. The tip of the ray floret is emarginate. The disc florets are yellow green in colour before anther dehiscence and yellow at anther dehiscence. The tubular disc florets are numerous, massed and clearly visible at all stages of flower development

Origin & Breeding History: 'Yolisette' is the product of a planned breeding program, conducted by Wendy R. Bergman of Yoder Brothers Inc. of Barberton, Ohio, USA. It originated from a cross made in May 1997 in Salinas, California between two proprietary Chrysanthemum seedling selections. It was discovered and selected by the breeder as a single flowering plant within the progeny of the stated cross grown in a controlled environment in Salinas, California. Selection was based on its uniform plant growth habit, desirable inflorescence form and floret colours, fast response time and excellent post production longevity. Asexual reproduction was initiated in July 1998, by vegetatively tip cuttings in a controlled environment in Fort Myers, Florida, USA.

Tests & Trials: Tests and trials were conducted at Yoder Canada Ltd. in Leamington, Ontario in the fall of 2004. Trials were performed under greenhouse conditions which approximate those used in commercial greenhouse practice. 40 unrooted cuttings of both the candidate and reference variety were directly stuck into 15 cm pots with 4 cuttings per pot. Plants were spaced 30 cm apart and were pinched once prior to short day treatment. The centre buds were removed on all plants. Observations and measurements were taken on 10 plants of each variety, and all colour measurements were made using the RHS Colour chart 2001.
