Description
CDC Greenstar (3339-3) is a high-yielding, large green conventional (non-imi tolerant) lentil variety. CDC Greenstar is the highest yielding large green lentil in the brown and dark brown soil zones. In 15 years of testing in the co-op and regional trials, it yielded 9% higher than CDC Greenland, 16% higher than CDC Impower and 6% higher than CDC Lima in the brown and dark brown soil zones. The yield gap is similar in the black and dark gray soil zones except compared to CDC Lima which yielded 5% higher than CDC Greenstar. Analysis of 11 years of Regional Variety Trial (RVT) yield data ranked CDC Greenstar at the top overall in the brown and dark brown soil zones and second in the black soil zone. CDC Greenstar has improved resistance to anthracnose (race 1) compared to currently produced large green lentil varieties. It is rated intermediate for resistance vs susceptible for CDC Greenland, CDC Impower and CDC Lima. Only the 2021 release, CDC Grimm has better resistance and is rated MR. It has a larger seed compared to CDC Impower or CDC Greenland.
Statistical analysis of 8 years of long-term RVT data ranked CDC Greenstar at the top for yield in the brown & dark brown soil zones and 2nd in the black soil zone among 4 historical and new large green lentil varieties (Figure 1).
Strengths
- Highest yielding large green lentil in the brown and dark brown soil zones
- Improved resistance to anthracnose (race 1) compared to other large green lentil varieties (rated intermediate)
Neutral
- Similar agronomic and maturity characteristics compared to CDC Greenland and CDC Impower
- Similar resistance to ascochyta blight as other large green lentil varieties
Weaknesses
- Not tolerant to imidazolinone
