Origin & Breeding History: 'Dektoshka' arose from crossing the proprietary seedling '04.88886.01' as the female parent with the proprietary seedling number '03.7793.05' as the male parent which was conducted in October, 2005 in Hensbroek, the Netherlands. It was selected from the resultant progeny in May, 2006 based on unique flower colour, flower size and good vase life. Asexual reproduction of the variety by cuttings was first conducted in Hensbroek in April, 2006 and was designated for commercialization in April, 2007.
Tests & Trials: The detailed description of 'Dektoshka' is based on the UPOV report of Technical Examination, application number 2008/1889, 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.
