Variety Description
Varieties used for comparison: 'Alsen', 'Go Early' and 'Carberry'
Summary: The intensity of anthocyanin colouration of the coleoptile is weak to medium on 'Rednet' whereas it is strong on 'Alsen' and absent or very weak on 'Go Early'. The plants of 'Rednet' head later than those of 'Carberry'. At maturity, the plants of 'Rednet' are taller than those of 'Alsen' and 'Carberry'. The spike of 'Rednet' is shorter than that of 'Go Early' and longer than that of 'Carberry'. The lower glume shoulder for 'Rednet' is sloping to straight whereas it is elevated to strongly elevated for 'Alsen'. The plants of 'Rednet' mature late in the season while the plants of 'Alsen' and 'Carberry' mature mid-season and the plants of 'Go Early' mature early in the season.
Description:
PLANT: common hard red spring wheat, erect to semi-erect growth habit at the 5 to 9 tiller stage, heads mid-season, matures late in season
SEEDLING: weak to medium intensity of anthocyanin colouration of coleoptile, glabrous sheath and blade of lower leaves
FLAG LEAF: absent or very weak anthocyanin colouration of auricles, medium glaucosity of sheath, glabrous blade and sheath
CULM NECK: absent or very weak to weak glaucosity, straight
STRAW (AT MATURITY): very thin pith in cross-section, no anthocyanin colouration
SPIKE: absent or very weak to weak glaucosity at heading, fusiform in profile, medium density, white at maturity, erect to incline attitude
AWNS: shorter than length of spike, white at maturity
LOWER GLUME: short to medium length, narrow to medium width, glabrous
LOWER GLUME SHOULDER: narrow, slightly sloping to straight
LOWER GLUME BEAK: short to medium, moderately curved
LOWEST LEMMA: slightly curved beak
KERNEL: medium red, small to medium sized, short to medium length, narrow to medium width, oval, rounded cheek, short brush hairs, medium to wide crease, shallow to medium crease
GERM: small, oval
DISEASE REACTION: resistant to Leaf Rust (Puccinia triticina), Stripe Rust (Puccinia striiformis) and Stem Rust (Puccinia graminis f. sp. tritici), moderately resistant to Fusarium head blight (Fusarium graminearum, Fusarium species), susceptible to Common Bunt (Tilletia caries, T. foetida)
Origin & Breeding History: 'Rednet' (experimental designations PT783 and UAW1149*064) originated from the cross (BYT10-07/ 'Carberry') / 'CDC Stanley' made in 2011 at the University of Alberta in Edmonton, Alberta. The F1 seed was sent to the Agriculture and Agri-Food Canada Research Centre for Double Haploid Production in Lethbridge, Alberta and the resulting 77 double haploid lines were planted in head rows in New Zealand during the 2012-2013 growing season. In 2013, 46 head rows were selected based on plant height, lodging, maturity and disease resistance and tested in replicated preliminary yield trials in Edmonton and Lethbridge and in disease nurseries in Edmonton, Lethbridge and Creston, Alberta. The line designated UAW1149*064 was selected and further evaluated in the Parkland Cooperative B test in 2014. It was further evaluated as PT783 in the Parkland Cooperative Registration Test from 2015 to 2017.
Tests & Trials: The comparative trials for 'Rednet' were conducted during the 2017 and 2018 growing seasons at the University of Alberta in Edmonton, Alberta. The plots were planted in a RCB design and consisted of 3 replicates for each variety. Each 4.5 metres squared plot consisted of 6 rows with rows being 4.5 metres in length and having a row spacing of 0.19 metres. The planting density was 300 plants per square metre. Measured characteristics were based on a minimum of 60 measurements per plant or parts of plants per variety. Mean differences were significant at the 5% probability level based on LSD values.
