Table II

Significance probabilities from two-tailed likelihood ratio tests used to test the homogeneity of family or within-family variances between a given pair of crossing designs, and estimated at different ages from planting.

Age (years) Family variance Within-family variance
SELF OP SELF OP
4 OP > 0.05 0.029
POL ≤ 0.001 ≤ 0.001 ≤ 0.001 ≤ 0.001
6 OP > 0.05 ≤ 0.001
POL 0.002 0.012 > 0.05 ≤ 0.001
10 OP 0.022 > 0.05
POL 0.033 > 0.05 ≤ 0.001 ≤ 0.001

The crossing designs are selfing (SELF), open pollination (OP) and outcrossing with Polymix (POL).
