Agronomic evaluation of four maize synthetics after recurrent selection for yield and evaluation of selected lines from the synthetics
… the yield of BSSS(R) and BS13(S(,2)); however, genetic drift may have caused significant yield reductions in BSCB1(R) and BS6(RS). BSSS(R) x BSCB1(R) and BS13(S(,2)) x BSCB1 (R) were improved similarly for yield indicating that both types of selection were equally effective for improving the …

Exploitation of nonadditive variance through nonrandom mating
Mixed model equations to predict additive and nonadditive genetic values also predict specific combining abilities or combination effects among sire and dams or among sires and maternal grandsires (mgs). Current mating programs, utilizing nonadditive genetic variance only by avoiding mating between …

Estimation of Variance Components in Finite Polygenic Models and Complex Pedigrees
Various models of the genetic architecture of quantitative traits have been considered to provide the basis for increased genetic progress. The finite polygenic model (FPM), which contains a finite number of unlinked polygenic loci, is proposed as an improvement to the infinitesimal model (IM) for …
