Estimation of general and specific combining ability effects in a diallel analysis of cross-pollinating populations, including the selfed parents, is presented in this work. The restrictions considered satisfy the parametric values of the GCA and SCA effects. The method is extended to self-pollinating populations (suitable for other species, without the selfed parents). The analysis of changes ...

The aim of this paper is to clearly demonstrate the potential ability of a similarity-based mating scheme to dynamically control the balance between the diversity of solutions and the convergence to the Pareto front in evolutionary multiobjective optimization. The similarity-based mating scheme chooses two parents in the following manner. For choosing one parent (say Parent A), first a pre-spec...

Heterosis is an effective way to increase yield and improve quality in alfalfa breeding. The key issue for efficiently use of heterosis identify parents having potential producing hybrid combinations with higher performance. This study aimed analyze genetic distance between the 48 accessions, combine different combinations. results showed that mating ability combination which both are tetraploi...

The objective of this study was to clarify how bias in genomic predictions is created by investigating a relationship among selection intensity, change heritability (?h2), and assortative mating (ASM). A heritability, resulting from selection, reflects the impact that Bulmer effect has on reduction between-family variation, whereas impacts within-family variance or Mendelian sampling variation....

This is an example of an observational study involving two variables of primary interest and several supplementary variables; these supplementary variables are ones that might affect the response variable and might also be correlated with the explanatory variable. The intent of the statistical analysis therefore is to produce the best possible description of the relationship between the two int...

Proper understanding of the mode gene action in open-pollinated varieties (OPVs) maize parents helps breeder choice appropriate breeding method to improve its genetic value. The objectives present study were determine controlling grain yield and other agronomic traits late maturing elite OPVs classify into heterotic groups. Ninety-one hybrids generated from 14 OPV using diallel mating design ev...

Considerable evidence from twin and adoption studies indicates that both genetic and shared environmental factors play a substantial role in the liability to antisocial behavior. Although twin and adoption designs can resolve genetic and environmental influences, they do not provide information about assortative mating, parent-offspring transmission, or the contribution of these factors to trai...

Cotton (Gossypium hirsutum L.) is an important cash crop worldwide, including Pakistan. the fibre that plays a vital role in Pakistan's economy. devotes major part to enhancing foreign exchange earnings and contributes 65 percent of total annual by exporting raw material finished products cotton. Identifying parents with higher yield contributing traits essential enhance economic yield. The dia...

The robustness of universal optimal binary balanced block (BBB) designs for diallel crosses has been investigated for the loss of any t (~1) observations (crosses) in a single block as per connectedness and A-efficiency criteria. It is observed that all the BBB designs for diallel crosses with the minimum eigenvalue strictly greater than 2 are robust as per connectedness criterion. Further A-ef...
