What is the effect of reducing cycle time?
Breeding programs aim to increase productivity of varieties in farmers fields. EiB proposes a fast and accurate population improvement approach as a strategy to release such improved varieties at a faster rate.
These simulation reports show the impact of reducing the cycle time in the short and long-term genetic gain and improve variety release.
