Origin & Breeding History: 'Cabaret' originated from a cross between 'Morag' and 'Maris Piper', made in 1988 in Cambridge, United Kingdom. Selection was initially made on single plants grown in Scotland using agronomic traits followed by several years of trials. These trials included replicated yield trials and disease trials to establish resistance to foliage and tuber blight, common scab, blackleg, virus, nematodes and storage rots. Consumer tests of boiling, frying, taste and damage resistance were also carried out concurrently over a ten year period.

Tests & Trials: Trials for 'Cabaret' were conducted in Albany, Prince Edward Island in 2005. The trial consisted of 25 foot single rows with four replications per variety. Measured characteristics were based on ten measurements and colour determinations were made using the 1995 RHS Colour Chart.
