Description

CDC Canary is an early maturing, yellow, semi-leafless field pea variety. CDC Canary was tested for two years in the field pea co-op registration Test “B” in 2013-2014. In these trials, the yield was 110% of the yellow pea check varieties CDC Golden and Agassiz (Table 2). In 10 years of testing in the co-op and regional trials in Saskatchewan (Table 1), CDC Canary yielded 99% and 100% of the check variety CDC Amarillo in the southern and northern geographies respectively. CDC Canary has PBR’91 protection. 

Statistical analysis of 8 years of long-term RVT data ranked CDC Canary 14th from the top for yield among 16 historical and new yellow pea varieties in the south and in the north (Figure 1).

Strengths

  • Early maturity 
  • Good lodging resistance, similar to CDC Amarillo 
  • Medium-long vine length 
  • Powdery mildew resistance 

Neutral

  • Medium seed size 
  • Round seed shape, and slightly blockier than the checks 
  • Moderate protein concentration (similar to CDC Amarillo) 
  • Moderate cooking time 
  • Rated fair for seed coat breakage
  • Fair resistance to Mycosphaerella blight resistance and Fusarium root rot
  • Moderate yield 

Weaknesses

  • Rated fair for seed coat breakage (similar to CDC Spectrum)
