Variety used for comparison: 'Waneta'

Summary: The lightsprout of 'Crop39' is small to medium in size while that of 'Waneta' is very small to small. The anthocyanin colouration at the base of the lightsprout for 'Crop39' has a strong to very strong intensity with a high proportion of blue while the anthocyanin colouration at the base of the lightsprout for 'Waneta' has a weak to medium intensity with an absent or low proportion of blue. The pubesence at the base of the lightsprout is a medium density for 'Crop39' while it is dense for 'Waneta'. The tip of the lightsprout for 'Crop39' has a strong intensity of anthocyanin colouration while that of 'Waneta' has a medium intensity. The lightsprout of 'Crop39' has many root tips while that of 'Waneta' has a medium number of root tips. At flowering, the plants of 'Crop39'are shorter than those of 'Waneta'. The anthocyanin colouration on the inner side of the corolla for 'Crop39' is a high extent of medium to strong intensity with a high proportion of blue while it is an absent or very low extent of absent or very weak intensity and an absent or low porportion of blue for 'Waneta'.

Origin & Breeding History: 'Crop39' (experimental designation 4353-3) originated from the cross between the variety 'Summer Delight', as the female parent, and the variety 'Coliban', as the male parent. The cross was conducted in 2000 at The New Zealand Institute for Plant and Food Research Limited, in Lincoln, New Zealand. The resulting seed was sown in the 2000-2001 growing season and the selected tubers were field planted in 2001. Selections were made through 10 more vegetatively propagated generations before the variety identified as 4353-3 was selected in 2013 for its yield; tuber shape, size and skin finish.

Tests & Trials: The comparative trial for 'Crop39' was conducted by Global Agri Services Inc. during the 2018 growing season in Drummond, New Brunswick. The trial consisted of a single, 21 metre long row per variety. Each row contained 70 plants spaced 0.3 metres apart with inter row spacing of 0.9 metres. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety. Mean differences were significant at the 5% probability level based on a Student`s t-test.
