The corolla of 'Eclipse' is white whereas it is red-violet on 'Yukon Gold'. The light sprouts of 'Eclipse' are ovoid in shape whereas they are spherical in 'Yukon Gold'. The intensity of anthocyanin colouration on the light sprout of 'Eclipse' is weak at the base and absent or very weak at the tip whereas it is strong at the base and weak at the tip on 'Yukon Gold'.

Origin & Breeding History: 'Eclipse' originated from the cross of 'Karlena' and 'Karatop', made in Gross Lüsewitz, Germany in 1988. The seedling was first selected in the field in 1989. Phenotypic recurrent selection tecnhiques were used over more than ten years to arrive at the final variety. Selection criteria included maturity, yield, disease resistance, morphological traits, storage characteristics and processing traits.

Tests & Trials: Trials for 'Eclipse' were conducted in Central Blissville, New Brunswick in 2008. All entries were planted in single-row plots. Plots consisted of rows 22 metres long spaced 91 cm apart with 30 cm in row spacing between plants. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
