Origin & Breeding History: 'Meiboulka' originated from a controlled cross-pollination conducted in 1999 in Le Luc en Provence, France. The parentage of the female parent was 'Kormax' x an unnamed variety and the parentage of the male parent was 'Meipoque' x 'Korimro'. In June 2001, one seedling was selected for its floriferousness and length of blooming period, as well as attractive foliage characteristics including dark colour and disease resistance.
Tests & Trials: Trials for 'Meiboulka' were conducted in a polyhouse during the summer of 2013 at Variety Rights Management in Oxford Station, Ontario. The trial included a total of 8 plants of the candidate variety and 15 plants of the reference variety. All plants were grown in 22 cm pots and spaced 45 cm apart. Observations and measurements were taken from 8 plants of the candidate variety and 10 plants of the reference variety, or 10 parts of plants of both varieties, in July 2013. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
