Description
CDC Citrine (5296-2) is a mid-maturing very high-yielding yellow pea that was one of the 3 highest yielding pea varieties after 4 years of testing in the Co-op and regional trials in Saskatchewan. Compared to the check variety CDC Amarillo, it yielded 108% in the south and 110% in the north (Table 1). It has very good standability; similar to CDC Amarillo and CDC Spectrum and medium-long vine length. Protein is moderate (0.5% higher than CDC Amarillo). It has slightly improved resistance to mycosphaerella blight and improved resistance to fusarium root rot vs. 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.
Strengths
- High yield in both north & south geographies
- Good seed characteristic package – rated good for:
- Resistance to seed coat breakage;
- Resistance to dimpling;
- Greenness (less green colouration) – better than CDC Inca or CDC Spectrum
- Round seed shape
- Good lodging resistance; similar to CDC Spectrum and CDC Amarillo, better than CDC Inca or CDC Meadow
- Rated moderately resistant to Fusarium root rot – similar to CDC Amarillo, better than CDC Spectrum
- Improved resistance to mycosphaerella blight – rated slightly better than CDC Amarillo
- Powdery mildew resistance
Neutral
- Medium maturity
- Medium-long vine length
- Medium seed weight, similar to CDC Amarillo
- Medium protein concentration, intermediate to CDC Amarillo and CDC Lewochko
