Summary Confidence interval estimators have not been described for several heritability (H) estimators relevant to recurrent family selection. Previously described H interval estimators do not apply to onefactor mating designs in split-plot in time experiment designs in one or more locations, one-factor mating designs for several experiment designs in two or more locations and years, and two-factor mating designs for several experiment designs in two or more locations or years. Our objective was to derive H interval estimators for these cases. H reduced to a function of constants and a single expected mean square ratio in every case; H=1−E(M′)/E(M″) where E(M′) is a linear function of expected mean squares and E(M″) is a single expected mean square. It was shown that F′=[M″/E(M″)]/[M′/E(M′)] has an approximate F-distribution with df″ and df′ degrees of freedom, respectively, where M′ and M″ are mean squares corresponding to E(M′) and E(M″), respectively. H is a function of F′, therefore, we used F′ to define an approximate (1−α) interval estimator for H.
