Description
CDC Athabasca is a large seeded yellow pea variety. In two years of testing in the field pea co-op registration trials in 2012–2013, CDC Athabasca yielded 107% of the check varieties CDC Golden and Agassiz (Table 2). The agronomic performance over seven years of testing in the co-op and regional trials in Saskatchewan is shown in Table 1. CDC Athabasca has PBR’91 protection.
Strengths
- Jumbo seed size
- Very good lodging resistance
- Medium vine length
- Powdery mildew resistance
Neutral
- Moderate yield relative to CDC Amarillo
- Medium maturity
- Round seed shape
- Moderate protein concentration (better than CDC Amarillo)
- Moderate cooking time
- Fair resistance to Mycosphaerella blight and Fusarium wilt
Weaknesses
- Rated ‘fair’ for seed coat breakage
