Critical issues in the use of diallel analysis are reviewed. From a statistical point of view the critical issue concerns the choice of a model with fixed or random genotypic effects. From a genetical point of view, two assumptions are critical in attempts to interpret the resuits of diallel analyses.

Biplot Analysis of Diallel Data
Crop Science, 2002Diallel crosses have been used in genetic research to determine the inheritance of important traits among a set of genotypes and to identify superior parents for hybrid or cultivar development. Conventional diallel analysis is limited to partitioning the total variation of the data into general combining ability (GCA) of each genotype and specific ...

Optimal complete diallel crosses
Biometrika, 1994SUMMARY Optimality of complete diallel crosses in incomplete blocks is investigated. Optimal complete diallel crosses are characterized, and such binary plans are derived using nested balanced incomplete block designs. A table of optimal complete diallel crosses for up to 15 lines is also provided.

DIALLEL‐SAS: A SAS Program for Griffing's Diallel Analyses
Agronomy Journal, 1997AbstractDiallel mating designs are generally used to obtain estimates of genetic effects for a fixed set of parental lines (fixed effects) or to estimate general combining ability (GCA) and specific combining ability (SCA) variance components from a set of randomly chosen parental lines (random effects) from multiple‐environment experiments.

Asymptotically efficient partial diallel crosses
Theoretical and Applied Genetics, 1990The asymptotic efficiency of partial diallel crosses is defined, and circulant plans having such a property are identified. In the absence of an optimal plan to suit his requirements, the breeder should opt for suggested plans to derive maximum information for given resources.

Reference Populations for Diallel Experiments
Biometrics, 1968Unbiased estimators, from a diallel experiment, were developed for genetic parameters of an equilibrium random mating population completely defined by the gene frequencies of the parents. Variations in the genetic model included additive, dominance, and additive X additive gene effects. The variances of the estimators for this reference population were

Serial analysis of combining ability in diallel and fractional diallel crosses in linseed
Theoretical and Applied Genetics, 1969An analysis of the nature of the gene action for seven characters influencing productivity and wide adaptation in Linum usitatissimum L. was undertaken in this investigation over three seasons based on diallel and fractional diallel crosses, among a set of ten genetically diverse parents.

ABSTRACTDiallel analyses can give different results depending on the model and the experimental design. A unified framework to fit and compare different models by mixed‐model packages is lacking. We, therefore, present a general diallel model and the required additional restrictions for the genetic variance–covariance structure to become equivalent to ...

A comparison of different diallel analyses
Theoretical and Applied Genetics, 1984Five different methods of diallel analysis have been compared using data from a half-diallel cross of a fixed set of nine homozygous varieties and one set of their single cross progenies in chickpea. The interrelationships among various parameters obtained from these analyses are reviewed and the advantages and disadvantages of each method discussed ...

Partial Diallel Crosses in Incomplete Blocks
Biometrics, 1995Various forms of diallel crosses play an important role in evaluating the breeding potential of genetic material in plant and animal breeding (e.g., Hinkelmann, 1975, inA Survey of Statistical Design and Linear Models, 243-269. Amsterdam: North Holland).
