Origin & Breeding History: 'Malwina' originated from the cross of an unnamed seedling (female parent) by 'Sophie' (male parent) conducted during the summer of 1999 in Kressbronn, Germany. 'Malwina' was initially selected from the seedling population based on plant vigour, plant growth habit and its late harvest season. Asexual propagation was first conducted in September 1999 in Kressbronn, Germany.

Tests & Trials: Comparative trials for 'Malwina' were conducted at the Simcoe Research Station, University of Guelph, Simcoe, Ontario during the 2014 growing season. The plots were planted in May 2013 in a randomized complete block design (RCBD). Each variety consisted of 2 replicates/variety with a total of more than 20 plants per variety. Plants were spaced approximately 35 centimetres between plants in the row and spaced approximately 1.3 metres apart between rows. Measured characteristics were based on 9 measurements.
