Origin & Breeding History: 'Sizzleness Yellow' is a product of a breeding and selection program which had the objective of finding colour mutants of the parent variety 'Sizzleness'. The new cultivar was discovered as a whole plant mutation in 2002 in a controlled environment (greenhouse) at CBA Research BV, Rijsenhout, The Netherlands. After its selection, 'Sizzleness Yellow' was vegetatively reproduced by cuttings and subjected to a testing program in order to evaluate uniformity, stability, distinctness and commercial value.

Tests & Trials: The detailed description of 'Sizzleness Yellow' is based on the UPOV Report of Technical Examination, application number 2004/0727, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted by the National Institute for Agricultural Botany in Cambridge, United Kingdom, in 2005. Colour determinations were made using the second edition (1986) Royal Horticultural Society (RHS) colour chart.
