Description
CDC Hickie is a mid-maturing, very high-yielding yellow pea. In seven years of testing in the Co-op and regional trials in Saskatchewan, it yielded 107% in the south and 106% in the north vs. the check variety CDC Amarillo. It has very good standability; similar to CDC Amarillo and CDC Spectrum and medium-long vine length. It is rated moderately resistant to Fusarium Root Rot, similar to CDC Amarillo and better than CDC Spectrum, CDC Lewochko or CDC Inca. It has good seed characteristics and is rated good for resistance to seed coat breakage, dimpling and greenness (Table 1). Protein is good, 0.5% higher than CDC Amarillo. CDC Hickie has PBR ’91 protection.
Statistical analysis of 8 years of long-term RVT data ranked CDC Hickie 3rd from the top for yield in the south and 10th in the north among 16 historical and new yellow pea varieties (Figure 1).
Strengths
- High yield, particularly in the south
- Moderately resistant to Fusarium root rot – better than CDC Inca, CDC Spectrum or CDC Lewochko
- Good seed characteristic package – rated good for:
- Resistance to seed coat breakage;
- Resistance to dimpling;
- Greenness (less green coloration) – better than CDC Inca or CDC Spectrum
Neutral
- Medium seed size (similar to CDC Amarillo)
- Medium maturity (1 day later than CDC Amarillo, 2 days later than AAC Lacombe)
- Medium long vine length
- Powdery mildew resistance
