CDC Pilar CLPlus

Wheat

Variety Description

Varieties used for comparison: 'CDC Abound', 'CDC Landmark' and 'AAC Brandon'

Summary: At booting, 'CDC Pilar CLPlus' has a medium to high frequency of plants with recurved flag leaves whereas 'AAC Brandon' has a high to very high frequency of plants with recurved flag leaves. The flag leaf auricles of 'CDC Pilar CLPlus' have an absent or very weak to weak intensity of anthocyanin colouration whereas those of 'CDC Abound' have a medium intensity of anthocyanin colouration. At maturity, the hairiness of the convex surface of the apical rachis segment for 'CDC Pilar CLPlus' is of a medium density whereas it is absent or very sparse for 'CDC Landmark'. The lower glume shoulder of 'CDC Pilar CLPlus' is straight whereas it is strongly elevated with a second point present for 'CDC Landmark'.

Origin & Breeding History: 'CDC Pilar CLPlus' (experimental designation PT598) originated from a controlled cross conducted in Swift Current, Saskatchewan between the line BW876 and the resultant progeny from a cross conducted between BW390 and IR05250 in 2006. The resultant F1 progeny was grown in a growth chamber during the winter of 2006-2007. The F2 plants were grown as a bulk plot in Saskatoon in 2007. The F3 generation was grown in a bulk plot in a winter nursery in New Zealand during the winter of 2007 and 2008. The F4 to F6 generations were grown in bulk plots in Saskatoon in 2008, 2009, and 2010 respectively. At the F7 generation selections were made for plant type and straw length. At the F8 generation, lines were grown in plots and selected for yield, plant height and straw length. PT598 was evaluated in the Western Wheat 'B' tests and in the Parkland Cooperative Test from 2016 to 2018.

Tests & Trials: The comparative trials for 'CDC Pilar CLPlus' were conducted at the University of Saskatchewan, Crop Science Field Facility in Saskatoon, Saskatchewan during the 2020 and 2021 growing seasons. There were 4 replications per variety arranged in an RCB design. Plots consisted of 5 rows, each row 3.6 metres long with an inter-row spacing of 0.23 metres. Measured characteristics were based on 40 measurements per variety per year.
