Variety used for comparison: 'Yukon Gold'
Summary: The lightsprout of 'Kikko' has an ovoid shape with a medium number of root tips while the lightsprout of 'Yukon Gold' is spherical with a few root tips. The lightsprout base of 'Kikko' has medium pubescence while it is dense in 'Yukon Gold'. The location of the anthocyanin on the stem in 'Kikko' is halfway up while it is along the entire stem in 'Yukon Gold'. 'Kikko' has a closed leaf while it is open in 'Yukon Gold'. The glossiness on the leaflet of 'Kikko' is medium to glossy while it is dull to medium in 'Yukon Gold'. 'Kikko' has an absent to a very low extent of anthocyanin colouration on the flower bud while it is medium to high in 'Yukon Gold'. The extent of anthocyanin colouration on the inside of the corolla of 'Kikko' is absent to very low while it is high for 'Yukon Gold'. The intensity of the anthocyanin on the inner side of the corolla is absent to very weak for 'Kikko' while it is weak to medium for 'Yukon Gold'. 'Kikko' matures very late while 'Yukon Gold' has early to medium maturity.

Origin & Breeding History: The origin of 'Kikko' is the result of the cross made in 1993 between 'Slaney' and C1992/42 at the Teagasc Oak Park Research Centre, Carlow, Co. Carlow, Ireland. The selection criteria included earliness, skin finish quality, disease resistance, yield and taste.
Tests & Trials: Tests and trials were conducted during the 2011 growing season in Drummond, New Brunswick. Plots consisted of 60 plants grown in a single row with a row length of 18.5 meters and a row spacing of 0.9 meters.
