Pea

Variety Description

Varieties used for comparison: 'CDC Meadow', 'CDC Amarillo', 'CDC Inca' and 'CDC Spectrum'

Summary: At the second flowering node, the stipule of 'CDC 5286-2' is larger than the stipule of 'CDC Inca' and wider than that of 'CDC Spectrum'. The pod of 'CDC 5286-2' is narrower than the pod of 'CDC Inca'. The pod curvature for 'CDC 5286-2' is absent or very weak while the pod curvature for 'CDC Meadow', 'CDC Amarillo' and 'CDC Spectrum' is weak. At the second fertile node, before seed development, the pod of 'CDC 5286-2' has less ovules than the pod of 'CDC Spectrum'. The hilum of 'CDC 5286-2' is darker in colour than the testa while those of the reference varieties are the same colour as the testa. The seed weight for 'CDC 5286-2' is greater than the seed weight of 'CDC Meadow' and less than that of 'CDC Spectrum'.

Origin & Breeding History: 'CDC 5286-2' originated from the cross between P3-E4-C1-22 and 'CDC Amarillo' conducted in 2012 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 7 F9 sub-lines selected to establish breeder seed in 2019. 'CDC 5286-2' 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 5286-2' 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.
