Table 1 Means and SD of each trait are given for both outbred and inbred plants in columns 1–4

  1. The units are mm for traits 2–4, √mm for trait 1, and Ln (days) for trait 5. The last column is the estimated directional dominance, β, of each trait (with SE) obtained from the ML procedure. β is expressed in units of outbred phenotypic standard deviations (see text) and is statistically nonzero for each trait.
