'Nectar' has a lightsprout base with a weak intensity of anthocyanin colouration and medium pubescence while the light sprout base of 'Yukon Gold' has a medium to strong intensity of anthocyanin with dense pubescence. The tip of the lightsprout in 'Nectar' has absent or very weak anthocyanin colouration and medium pubescence while the tip of the light sprout of 'Yukon Gold' has medium intensity of anthocyanin with sparse pubescence. 'Nectar' has an absent or very low extent of anthocyanin colouration on the stem while the stem of 'Yukon Gold' has a low to medium extent of anthocyanin. 'Nectar' has a taller plant height than 'Yukon Gold'. The leaf of 'Nectar' has a closed to intermediate openness while it is open in 'Yukon Gold'. 'Nectar' has a low frequency of coalescence of the terminal and lateral leaflets while it is absent or very low in 'Yukon Gold'. The extent of anthocyanin colouration on the flower bud of 'Nectar' is absent or very low while it is medium to high in 'Yukon Gold'. The corolla of 'Nectar' is large with an absent or very low extent of anthocyanin colouration on the inner side while the corolla of 'Yukon Gold' is medium sized with a large extent of anthocyanin. The anthocyanin on the inner side of the corolla of 'Nectar' is absent or very weak in intensity while it is weak to medium for 'Yukon Gold'.

Origin & Breeding History: The origin of 'Nectar' is the result of the cross made in 1992 between 'Famosa' and 'Red Cara' 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.
