Estimates of least-squares means (LSM), population-level inbreeding depression (ID) and population-level outcrossing rate (t), based on progeny data from three crossing designs - selfing (SELF), open-pollination (OP) and outcrossing with Polymix (POL). The traits evaluated at different ages were survival (SURV), basal area per hectare (BAH) and breast-height diameter (DBH). The significance probabilities pertaining to the tests of differences between pairs of LSM estimates are presented for each trait and age (***, P ≤ 0.001; **, P ≤ 0.01; *, P ≤ 0.05; ns, P > 0.05).
