Table 1.
Estimated rates of evolution of plants experiencing artificial selection for early flowering (Early) or long leaf length at reproduction (Long) in hybrid and wild radish lineages
| Lineage | Trait | Darwins (×10−3)* |
|---|---|---|
| Hybrid Long | Leaf length | 92.5 |
| Hybrid Long | Age at flowering | 76.3 |
| Hybrid Early | Age at flowering | 75.9 |
| Wild Long | Age at flowering | 58.7 |
| Wild Long | Leaf length | 45.1 |
| Hybrid Early | Leaf length | 36.4 |
| Hybrid Early | Pollen fertility | 33.8 |
| Wild Early | Age at flowering | 31.3 |
| Wild Early | Leaf length | 20.7 |
| Hybrid Long | Pollen fertility | 18.8 |
*
Darwins = |(ln(x2) − ln(x1))/t| (Haldane, 1949) where x1 is the mean trait value for control lineages and x2 is the mean trait value of selected lineages, t is time in millions of years (4 years).
