Variety Description
Varieties used for comparison: 'CDC Meadow', 'CDC Amarillo', 'CDC Inca' and 'CDC Spectrum'
Summary: The stipule of 'CDC Hickie' is longer than the stipule of 'CDC Inca'. The plants of 'CDC Hickie' flower mid to late season while those of 'CDC Meadow', 'CDC Amarillo' and 'CDC Spectrum' flower early to mid-season. The flower standard of 'CDC Hickie' has a moderately raised to level shaped base while that of 'CDC Meadow' has a level to moderately arched base. The pod of 'CDC Hickie' is wider than the pods of 'CDC Meadow' and 'CDC Spectrum'. At maturity, the stem, including the first two nodes, of 'CDC Hickie' is longer than that of 'CDC Spectrum'.

Origin & Breeding History: 'CDC Hickie' (experimental designation CDC 4900-13) originated from the cross between 'CDC 2283-17' and PO410-16 conducted in 2011 at the Crop Development Centre at the University of Saskatchewan, Saskatoon, Saskatchewan. The variety was developed from a single plant selection from the F2 population with 20 F9 sub-lines selected to establish breeder seed in 2019. 'CDC Hickie' was selected based on grain yield, days to maturity, vine length, resistance to lodging, seed weight, resistance to seed coat breakage, disease resistance, crude protein concentration and cooking time.
Tests & Trials: The comparative tests and trials for 'CDC Hickie' were conducted at the Sutherland Field Site of the Crop Development Centre of the University of Saskatchewan, Saskatoon, Saskatchewan during the 2019 and 2021 growing seasons. The trials were arranged in a RCB design consisting of 2 replications per variety. Each replicate consisted of 3 rows spaced 30 cm apart, with a row length of 3.66 metres and a planting density of 84 seeds per square metre. The measured characteristics were based on 20 measurements per variety per year, except for seed weight which was based on 8 measurements per variety per year. The mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
