Pea

Variety Description

Varieties used for comparison: 'CDC Hickie', 'CDC 4999-5', 'CDC 5286-2' and 'CDC 5301-1'

Summary: The pod of 'CDC Citrine' is longer than the pods of 'CDC Hickie', 'CDC 4999-5', and 'CDC 5286-2'. The pod of 'CDC Citrine' is wider than the pod of 'CDC 4999-5'. At maturity, the stem, including the first two nodes of 'CDC Citrine' is shorter than the stems of 'CDC 4999-5' and 'CDC 5301-01'. The 100 seed weight of 'CDC Citrine' is greater than the 100 seed weight of 'CDC 5286-2' and less than those of 'CDC Hickie' and 'CDC 5301-1'.

Origin & Breeding History: 'CDC Citrine' (experimental designation CDC 5296-2) originated from the cross between 'P3-E4-CO-18' / 'CDC Amarillo' and 'MP 1907' conducted in the fall of 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. At the F9 generation, 40 sub-lines were selected to establish breeder seed in 2020. 'CDC Citrine' 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 Citrine' were conducted at the Sutherland Field Site of the Crop Development Centre of the University of Saskatchewan, Saskatoon, Saskatchewan during the 2021 and 2022 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.
