Description
CDC Impulse (IBC-479) is a high yielding Clearfield® small red lentil that is well-adapted to the Brown and Dark Brown soil zones. In nine years of testing in the co-op and regional trials in Saskatchewan, CDC Impulse yielded 108% of CDC Maxim in the Brown and Dark Brown soil zones, and 95% in the Black and Dark Grey soil zones (Table 1). Maturity is slightly later than CDC Maxim, positive for the southern regions of the lentil production zone. Seed type is larger in diametre and seed weight, acceptable for specific segments of the dehulled red lentil market (Table 2). CDC Impulse has PBR’91 protection.
Strengths
- Seed type suitable for segments of the small red cotyledon lentil market
- High yield compared to CDC Maxim
- Imidazolinone tolerance
- Seed weight and diameter is greater than CDC Maxim.
- Later maturing than CDC Maxim
- Taller than CDC Maxim
Neutral
- Similar in disease ratings and lodging resistance compared to CDC Maxim
