Description
CDC Coral was tested for two years in the Lentil Registration Recommendation Trial “A” in 2012-2013. In these trials, CDC Coral yielded 110% of CDC Maxim (Table 1). In five years of testing in the co-op and regional trials in Saskatchewan (Table 4), CDC Coral yielded 110% of CDC Maxim in the Brown and Dark Brown soil zones and 106% in the Black and Dark Gray soil zones. Seed coat colour and cotyledon colour of CDC Coral are similar to that of CDC Maxim. The disease resistance profile is similar to that of CDC Maxim. Lodging scores for CDC Coral are improved compared to CDC Maxim (Table 2), and flowering is delayed by two days compared to CDC Maxim. Seed diametre and seed thickness were slightly less than that of CDC Maxim, but still acceptable for the small red lentil market class (Table 3). Application for PBR’91 protection for CDC Coral has been submitted.
Strengths
- High yield compared CDC Maxim
- Improved lodging score compared to CDC Maxim
Neutral
- Similar maturity and disease resistance characteristics compared to CDC Maxim
- Later flowering than CDC Maxim
- Seed appearance similar to CDC Maxim
- Seed diameter and thickness slightly less than CDC Maxim
Weaknesses
- Not tolerant to imidazolinone herbicides
