Description

CDC Spruce is a green cotyledon, semi-leafless field pea variety. In 13 years of testing in the co-op and regional trials in Saskatchewan, CDC Spruce yielded 5% higher than CDC Greenwater in the north but 2% lower in the south (Table 1). Relative to the yellow pea check variety CDC Amarillo, CDC Spruce yielded 97% in the south and 98% in the north. CDC Spruce has PBR protection. 

Statistical analysis of 9 years of long-term RVT data ranked CDC Spruce 5th from the top for yield in the south and 4th in the north among 8 historical and new green pea varieties (Figure 1).

Strengths

  • Powdery mildew resistance
  • Good resistance to bleaching 

Neutral

  • Good lodging resistance, similar to CDC Forest 
  • Medium maturity 
  • Medium vine length 
  • Medium seed size 
  • Round seed shape 
  • Moderate cooking time 
  • Fair resistance to Mycosphaerella blight and Fusarium root rot

Weaknesses

  • Rated fair for seed coat breakage and dimpling
