The diallel cross: the ultimate mating design? [PDF]
, 1998 One can only agree with Hallauer and (1988) when they state that the ‘diallel mating design has been used and abused more extensively than any other …’. Much of the controversy surrounding it stems from the nature of the population under test and the type of analysis required (Wright, 1985). In order to dispel some of this controversy we shall consider

The diallel method used by Anisman (1976a) involves crossing each strain with every other reciprocally so that, as in this case, the use of three parental strains generates a 3 × 3 diallel table of family means in which the reciprocal crosses, by which prenatal maternal effects can be detected (see Section 9.1), are distributed symmetrically around the

Diallel cross in swine production: A review
Indian Journal of Animal Research, 2017A review of diallel cross and its influence on different genetic and crossbreeding parameters derived in swine production is attempted following its application by various researchers. With different genetic models developed by different researchers from the 1950’s till date, diallel cross methodology and its application in animal breeding ...

Genetic interpretation and analysis of diallel crosses with animals
Theoretical and Applied Genetics, 1983A genetic framework was developed for the interpretation of statistical parameters estimated from a diallel experiment among a fixed set of lines. These included average direct genetic, average maternal genetic, general combining ability, reciprocal, and line and specific direct and maternal heterotic effects.

Missing Techniques in Complete Diallel Crosses
Biometrical Journal, 1986AbstractThe missing of observations in agricultural field experiments is quite common due to several natural hazards and at present no method of analysis of diallel crosses exists when one or two observations are missing. Therefore, the method of combining ability analysis of diallel crosses (including parents and reciprocals) for one and two missing ...

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).

Evaluation of circulant partial diallel crosses in maize
Theoretical and Applied Genetics, 1978The present study was conducted in maize (Zea mays L.) on crosses among 20 diverse parents. The materials were evaluated in four different environments for eight characters. Combining ability analysis was carried out following diallel and partial diallel crosses.

Partial Diallel Cross in Multi‐environment
Biometrical Journal, 1978AbstractAnalysis of partial diallel cross repeated over environments is discussed. Formulae are given to estimate the general combining ability effects and their interaction effects with environments. Analysis of variance table along with expected mean squares is given.

A diallel cross for mating speeds inDrosophila melanogaster
Genetica, 1964A diallel cross inDrosophila melanogaster for the mating speeds of previously unmated pairs aged 6 days was carried out for 6 inbred lines and their hybrids. Pairs were observed for 40 minutes. There was extreme hybrid vigour especially in mating frequency for ≤10 minutes but the degree of hybrid vigour was relatively smaller for ≤40 minutes ...
