Table I
Results from ASReml analyses. Three types of analyses were run: (a) half-sib analysis (model 1); (b) full-sib analysis – only additive effects estimated (model 1) and (c) full-sib analysis – both additive and dominance effects estimated (model 2). Columns 2 and 4: DA is the test statistic of the REML likelihood ratio test, used to test the significance of the additive genetic effects estimated in model 1. Columns 3 and 5: single tree heritabilities (h2) and corresponding standard errors for six characters, using variance components from either half- or full-sib analysis (model 1). Column 6: correlation between breeding values (BVs) estimated for the 23 parent clones in FP.620 using either half- or full-sib analysis (both model 1). Column 7: DD is the test statistic of the REML likelihood ratio test, used to test the significance of the dominance effects estimated in model 2.
