CDC Succession CLPlus

Wheat

Variety Description

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

Summary: At booting, the flag leaf auricles of 'CDC Succession CLPlus' have a weak to medium intensity of anthocyanin colouration whereas those of 'CDC Landmark' and 'AAC Brandon' have an absent or very weak intensity of anthocyanin colouration. The straw pith of 'CDC Succession CLPlus' is thin to a medium thickness in cross section whereas it is medium to thick for 'CDC Abound'. At maturity, the hairiness of the convex surface of the apical rachis segment for 'CDC Succession CLPlus' is of a medium density whereas it is absent or very sparse for 'CDC Landmark'. The lower glume shoulder of 'CDC Succession CLPlus' is straight whereas it is strongly elevated with a second point present for 'CDC Landmark'.

Origin & Breeding History: 'CDC Succession CLPlus' (experimental designation BW5031) originated from a controlled cross conducted in Swift Current, Saskatchewan between the line BW876 and resultant progeny from a cross conducted between the lines 05F0071 and IR05030 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 2007-2008. 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 based on plant type and straw length. Selected F8 lines were grown in hill plots and further selections made based on yield, plant height, and straw length. One line designated as BW5031 was entered in the Western Wheat Cooperative tests from 2016 to 2018.

Tests & Trials: The comparative trials for 'CDC Succession 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.
