Table I
Estimated family and within-family variances, and respective coefficients of variation, for DBH based on progeny data from three crossing designs – selfing (SELF), open pollination (OP) and outcrossing with Polymix (POL) – at different ages from planting. The significance probabilities refer to one-tailed likelihood ratio tests, used to test the departure of the family variance estimates from zero.
