Origin & Breeding History: 'Mozart' originated from a cross between 'Redstar' and 'Caesar', made at Metslawier, The Netherlands in 1991. The variety was selected from the F1 of the cross. Selection criteria included yield, internal and external quality and resistance to diseases and pests.
Tests & Trials: Trials for 'Mozart were conducted in Drummond, New Brunswick in 2006. All entries were planted in single-row plots. Plots consisted of rows 22 metres long with 30 cm in row spacing and between row spacing of 91 cm. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
