A comparison of simulated genetic gains based on three breeding scenarios
| Metrics | One cycle, 4 years/cycle, h2 = 0.3 | Four cycles, 1 year/cycle, h2 = 0.2 | Four cycles, 1 year/cycle, h2 = 0.15 |
|---|---|---|---|
| Number of lines phenotyped per cycle | 1000 | 100 | 100 |
| Total genetic gain (kg ha−1) | 455 | 954 | 686 |
| Annual genetic gain (kg ha−1 yr−1) | 113.75 | 238.5 | 171.5 |
| Genetic standard deviation units per year | 0.32 | 0.82 | 0.68 |
| % genetic gain per year | 2.22 | 4.66 | 3.35 |
