Variety Description

Variety used for comparison: 'Kennebec'

Summary: The base of the lightsprout of 'Crop60' has a very strong intensity of anthocyanin colouration with a high proportion of blue while that of 'Kennebec' has a weak to medium intensity of anthocyanin colouration with a medium proportion of blue. The stem of 'Crop60' has a medium extent of anthocyanin colouration on the lower three quarters of the stem while that of 'Kennebec' has an absent or very low extent of anthocyanin colouration along the entire stem. The second pair of lateral leafets of 'Crop60' are medium sized while those of 'Kennebec' are very large. The plants of 'Crop60' are taller than those of 'Kennebec'. The tuber of 'Crop60' has reddish brown skin and shallow eyes while the tuber of 'Kennebec' has light beige skin and eyes of medium depth.

Origin & Breeding History: 'Crop60' originated from a cross conducted between 'Apassionate' as the female parent and 'Karaka' as the male parent at The New Zealand Institute for Plant & Food Research Limited in Lincoln, New Zealand in 2004. Seed from the cross was grown in a greenhouse in 2005 to 2006 with resulting tubers planted in a field in Lincoln, New Zealand in 2006. Selections were conducted through 8 generations with 'Crop60' being selected in 2013 based on qualities for french fry production.

Tests & Trials: The comparative trial for 'Crop60' was conducted by Global Agri Services Inc. in Central Blissville, New Brunswick during the 2021 growing season. The field trial consisted of a single, 20 metre long row per variety. Each row contained 65 plants spaced 0.3 metres apart with inter-row spacing of 1.1 metres. Measurements were taken from 10 plants, or 10 parts of plants, of each variety. The mean difference was significant at the 5% probability level based on a paired Student's t-test. Lightsprout characteristics were assessed on 10 tubers harvested from the comparative trial and observed approximately 2.5 to 3 months after sprouting was promoted by exposing the tubers to an external agent.
