CDC Tollefson
CDC Tollefson is a mid-maturing, very high yielding yellow pea. After 7 years of testing in the Co-op and Regional Variety trials in Saskatchewan, it was the highest yielding variety in the south yielding 109% of the check variety CDC Amarillo. It also yields high in the north at 108% of the check. This represents a 4 – 6% yield increase vs. the current CDC varieties CDC Inca, CDC Spectrum and CDC Lewochko. It has very good standability; similar to CDC Amarillo and CDC Spectrum and medium-long vine length. It has improved disease resistance vs. CDC Spectrum, CDC Lewochko or CDC Inca and is rated moderately resistant to Fusarium root rot. It has good seed characteristics and is rated good for resistance to seed coat breakage, dimpling and greenness. Protein is similar to CDC Amarillo. CDC Tollefson has PBR’91 protection.
Statistical analysis of 8 years of long-term RVT data ranked CDC Tollefson 2nd from the top for yield in the south and 7th in the north among 16 historical and new yellow pea varieties.
