Origin & Breeding History: The variety 'Dekorlina' originated from a cross made in Hensbroek, Netherlands in November 2005. The female parent was a proprietary seedling designated 41418 and the male parent was a proprietary seedling designated 04.41621.03. The new variety was selected from the resultant progeny in April 2006, based on its pure yellow ray florets, dark green flower centre, good spray formation and good flower size. Asexual reproduction of the variety by cuttings was first conducted in Hensbroek in June 2006 and was designated for commercialization in December 2006.

Tests & Trials: The detailed description of 'Dekorlina' is based on the UPOV report of Technical Examination, application number 2007/2960, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted by The National Institute of Agricultural Botany (NIAB) in Cambridge, United Kingdom, in 2009. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart, 5th edition.
