Description

CDC Rider (4506-4) is a mid-maturing high-yielding green pea. In testing in the Co-op and regional trials in Saskatchewan, it yielded 101% in the south and 98% in the north vs. the check variety CDC Amarillo (Table 1). It has very good standability, slightly better than CDC Limerick and CDC Raezer. Protein is similar to CDC Amarillo check and CDC Forest. It has improved resistance to fusarium root rot vs. CDC Limerick, CDC Spruce, and CDC Forest and improved resistance to mycosphaerella blight compared to CDC Forest, CDC Raezer and CDC Spruce. It has good seed characteristics with round seed shape similar to CDC Limerick and rounder than CDC Greenwater. It is rated good for resistance to seed coat breakage, dimpling and bleaching. CDC Rider is showing improved lodging and disease package compared to CDC Forest while maintaining top yields for green peas. 

Strengths

  • High yield particularly in the brown, dark brown, and south black soil zone regions 
  • Good seed characteristic package – rated good for: 
    • Resistance to seed coat breakage; 
    • Resistance to dimpling; 
    • Bleaching; 
  • Round seed shape – similar to CDC Limerick, rounder than CDC Greenwater 
  • Good lodging resistance; better than CDC Limerick, similar to CDC Greenwater 
  • Rated moderately resistant to Fusarium root rot – better than CDC Forest, CDC Limerick, or CDC Spruce 
  • Improved resistance to mycosphaerella blight – better than CDC Forest, CDC Raezer, or CDC Spruce 
  • Powdery mildew resistance 

Neutral

  • Medium maturity 
  • Medium-long vine length 
  • Medium seed weight, similar to CDC Amarillo 
  • Medium protein concentration, similar to CDC Amarillo and CDC Forest
