Description
CDC Forest is a green cotyledon, semi-leafless field pea variety. In two years of testing in the field pea co-op registration trial in 2013–2014 CDC Forest yielded 117% of the green pea check varieties CDC Striker and Cooper (Table 2). In six years of testing in the co-op and regional trials in Saskatchewan (Table 1), CDC Forest was the top yielding green pea in both geographies. CDC Forest has PBR’91 protection.
Strengths
- High yield (greater than or equal to CDC Amarillo)
- Yield stability over different soil zones
- Powdery mildew resistance
Neutral
- Good lodging resistance
- Medium vine length
- Medium maturity
- Medium seed size (equal to CDC Amarillo)
- Round seed shape (blockier than CDC Striker, rounder than Cooper)
- Low seed coat breakage per cent
- Good bleaching resistance
- Moderate protein concentration
- Moderate cooking time
- Fair resistance to Fusarium and Mycosphaerella
