Origin & Breeding History: The variety 'Balvoyelo' originated from a cross pollination conducted in August 2006 at Santa Paula, California, USA. The female parent was a proprietary breeding selection designated 10512-1, characterized by its light yellow flower colour, medium green foliage colour and upright growth habit. The male parent was a proprietary selection designated 10013-1, characterized by its bright yellow flower colour, medium green foliage colour and trailing growth habit. The initial selection was made in February 2007 and asexual propagation since that time has been through the use of vegetative cuttings. The variety was selected for its bright yellow flower colour and floriferousness.

Tests & Trials: Trials for 'Balvoyelo' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. The trial included a total of fifteen plants of the candidate and reference varieties. Rooted cuttings were transplanted into 11 cm pots on April 28, 2010. Observations and measurements were taken from ten plants or parts of plants on June 9, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
