CDC Inca yellow pea

CDC Inca is a yellow cotyledon, semi-leafless field pea variety. It was registered and released to Select Seed Growers in Saskatchewan, Alberta and Manitoba in 2015.

CDC Inca was tested for two years in the Field Pea Co-op Registration Test “B” in 2011 – 2012. In these trials, the yield was 114% of the yellow pea check varieties CDC Golden and Agassiz. In 5 years of testing in the Coop and Regional trials in Saskatchewan, CDC Inca yielded 6% higher than CDC Amarillo (new check variety) in the southern regions and 100% in the north. In the 2016 Manitoba Field Pea Variety Trials, CDC Inca was the highest yielding yellow pea. In the 2016 Alberta Performance Trials, CDC Inca yielded 104% of CDC Amarillo.  CDC Inca has PBR protection.

Main strengths:

  • Improved yield compared to the yellow check varieties
  • Good lodging resistance; better than the checks CDC Golden and Agassiz
  • Medium vine length
  • Powdery mildew resistance
