Variety Description

Varieties used for comparison: 'Conquer', '5701PR' and 'AAC Crossfield'

Summary: The growth habit of the plants of 'AAC Entice' is erect while it is semi-prostrate for 'Conquer'. The frequency of plants with recurved flag leaves on 'AAC Entice' is medium whereas the frequency is high in 'Conquer' and '5701PR'. The anthocyanin colouration of the auricles of the flag leaf of 'AAC Entice' is absent or very weak whereas it is strong for that of 'Conquer'. The spike glaucosity of 'AAC Entice' is medium while it is absent or very weak for 'Conquer'. The spike of 'AAC Entice' has a fusiform shape in profile while that of 'Conquer' has a semi-clavate shape. The neck of the culm of 'AAC Entice' is straight and has absent or very weak glaucosity whereas that of '5701PR' is curved and has weak glaucosity. The plants of 'AAC Entice' are shorter than those of 'Conquer' and taller than those of '5701PR'. The shoulder shape of the lower glume of 'AAC Entice' is sloping whereas it is strongly elevated with a second point present for 'Conquer', it is slightly sloping for '5701PR' and it is straight for 'AAC Entice'. The shoulder of the lower glume of 'AAC Entice' is narrow whereas that of 'Conquer' is very broad and that of '5701PR' and 'AAC Crossfield'are of medium width. 'AAC Entice' has a lower thousand kernel weight than 'Conquer' and 'AAC Crossfield'.

AGRONOMIC CHARACTERISTICS: good resistance to shattering, fair resistance to pre-harvest sprouting

BREAD MAKING QUALITY: good

DISEASE REACTIONS: resistant to Leaf rust (Puccinia recondita) and Stripe rust (Puccinia striiformis), moderately resistant to Stem rust (Puccinia graminis f. sp. tritici), moderately susceptible to Fusarium head blight (Fusarium graminearum, Fusarium species) and Loose smut (Ustilago tritici)

INSECT REACTION: susceptible to Wheat Midge (Sitodiplosis mosellana)

Origin & Breeding History: 'AAC Entice' (experimental designation HY1627) was developed from the cross Howard / 2*5701PR made at the Agriculture and Agri-Food Canada Cereal Research Centre in Winnipeg, Manitoba in 2005. F2 plots were planted at Glenlea, Manitoba in 2006. F3, F5 and F7 generations were grown in contra-season years in nurseries in New Zealand (Palmerston North). In 2008, 13 F6 lines were evaluated in single-replicate yield trials at three locations (Glenlea, Brandon and Saskatoon). F7:8 lines were evaluated in a 2009 F8 Yield Trial planted at Brandon, Glenlea and Saskatoon using criteria similar to the F5 generation. F7:9 lines were evaluated in the 2010 Eastern Prairie Wheat A4 level tests (in Saskatchewan and Manitoba) while 4 lines advanced to the 2011 Eastern Prairie Wheat B tests. Based on agronomic performance, HY1627 was advanced to the 2012 High Yield Wheat Cooperative Registration Trial from 2012 to 2014. Selection criteria included disease resistance, agronomic appearance, yield, kernel appearance and quality.

Tests & Trials: Trials for 'AAC Entice' were conducted during the summers of 2015 and 2016, with the exception of height data measurements that were taken in 2015 and 2017, at Fairfield Farm in Lethbridge, Alberta. Plots that were 2.76 squared metres consisted of 4 rows with a row spacing of 23 cm and a row length of 3 metres. There were 3 replications arranged in an RCB design with 250 plants per square metre and 700 plants per plot.
