Varieties used for comparison: 'Chieftain' and 'Norland'
Summary: The shape of the lightsprouts of 'AAC Poppy and 'Chieftain is ovoid whereas the shape is broad cylindrical for 'Norland. The lightsprout tip of 'AAC Poppy has a closed habit whereas that of the reference varieties has an intermediate habit. The plant growth habit of 'AAC Poppy is upright whereas it is semi-upright for 'Chieftain and spreading for 'Norland. The extent of anthocyanin colouration on the stem is high and along the entire length for 'AAC Poppy whereas the anthocyanin colouration is of medium extent and along the entire length for 'Chieftain and is low and present only at the base of the stem for 'Norland. Anthocyanin colouration on the upper side along the midrib of the leaf is of high extent and strong intensity for 'AAC Poppy whereas the extent of anthocyanin colouration is absent or very low with absent or very weak intensity for 'Norland. The plants of 'AAC Poppy are shorter than those of 'Norland. The frequency of inflorescences per plant is low to medium for 'AAC Poppy whereas the frequency is high for 'Chieftain. The intensity of anthocyanin colouration on the inner side of the flower corolla is strong to very strong for 'AAC Poppy whereas it is medium for 'Chieftain. The tubers of 'AAC Poppy are oval in shape with a cream coloured flesh whereas the tubers of the reference varieties are long oval in shape with white flesh.

Origin & Breeding History: The origin of 'AAC Poppy (experimental designations 'AR2011-06, 'F05056 and '15002-06) is the result of the cross between the variety 'Glenwood Red as the female parent and the variety 'F92028 as the male parent conducted at the Agriculture & Agri-Food Canada Potato Research Centre in Fredericton, New Brunswick in 2000. 'AAC Poppy was selected in 2005 based on its adaptation as a clonal selection, tuber type and fresh market potential.
Tests & Trials: Trials for 'AAC Poppy' were conducted in 2013 at the Potato Research Centre of Agriculture and Agri-Food Canada in Fredericton, New-Brunswick. There were two replicates. Each replicated 640 metres squared plot consisted of 60 plants grown in two rows with a row length of 7.5 metres and a row spacing of 0.9 metres between rows. Plants were spaced 0.25 metres apart. The measured characteristics were based on 10 measurements per variety. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
