Description
CDC Imp is an extra-small red lentil of Clearfield® variety. In five years of testing in the in the co-op and regional trials in Saskatchewan, CDC Imp was the top yielding Clearfield® extra-small red lentil variety. It yielded 95% of the small red lentil check variety CDC Maxim in the south, and 98% in the north (Table 1). The seed diametre of CDC Imp is similar to CDC Impala however, it has greater seed thickness making CDC Imp more suitable for dehulling (Table 2). Application for PBR’91 protection for CDC Imp has been submitted to CFIA.
Strengths
- Seed thickness slightly greater than that of CDC Impala
- Imidazolinone tolerance
- High yield compared to other Clearfield® extra-small reds
- Taller than other extra small red varieties
Neutral
- Early-mid maturity
- Similar disease resistance as CDC Maxim and other extra-small red varieties
Weaknesses
- Lower yielding than non-Clearfield® extra-small red varieties
