Description
CDC 1142 is a white-flowered, low tannin, Low Vicine/Convicine (LVC) faba bean variety. The LVC trait represents an opportunity for using faba bean protein in food ingredients, creating new markets for faba beans. The faba bean industry is transitioning to LVC varieties and all new varieties must have this trait. Due to the outcrossing nature of faba beans, isolation of LVC faba beans from high vicine types and testing for the integrity of the LVC status of harvested seed is required. For these reasons, this variety has been sub-licensed in a nonexclusive, closed-loop production basis for the purpose of trait stewardship. Current sub-licensees include KGB Meier Farms, Dutton Farms Partnership and Faba Canada.
In 5 years of testing in the Co-op and Regional trials in Saskatchewan, CDC 1142 yielded 98% of the current market class check CDC Navi (Table 1). In 4 years of head-to-head testing, CDC 1142 yielded 4% higher vs. Snowbird. CDC 1142 matures 4 days earlier than Navi and 2 days later than Snowbird. CDC 1142 has a small seed that is 76% of Snowbird (358 vs. 471 g/1000) and 85% vs. Navi. Application for PBR’91 protection for CDC 1142 has been submitted.
Strengths
- Low Vicine/Convicine (LVC)
- Higher yielding than Snowbird; similar to Navi
- Matures 4 days earlier than Navi
- Small seed size
Neutral
- Similar height and lodging compared to Snowbird or Navi

1 Long term average yield of check varieties: Fabelle: 4609 kg/ha or 69 bu./ac., Navi: 3930 kg/ha or 58 bu./ac.
2 Lodging score (1-9) where 1 = completely upright, 9 = completely lodged.
Faba beans are classified into Tannin and Low (Zero) Tannin (ZT) types. For this table comparisons for Tannin types are made to Fabelle and low tannin types to Navi.
