TATISTICAL methods for the analysis of continuous variation have been S developed using second degree statistics such as variance and covariance and successfully applied to crosses between two inbred lines. These have allowed the recognition of the more familiar phenomena associated with Mendelian genetics although they appear in the analyses in a new and less obvious form (MATHER 1949; BATEMAN...

Restriction fragment length polymorphisms (RFLPs) were used as markers to monitor mitochondrial inheritance in the cellular slime mold, Polysphondylium pallidum. When two opposite mating types (mat1 and mat2) of closely related strains were crossed, all the haploid progeny regardless of mating type inherited their mitochondrial DNA from the mat2 parent only. When opposite mating types from more...

Few studies have evaluated vegetable soybean for sugar content at the green pod stage. Information on combining ability and type of gene action that governs inheritance of seed traits can help breeders to select suitable parents and devise an appropriate breeding strategy. Ten vegetable soybean accessions were crossed in a complete diallel mating design. Parent lines and F2 and F3 progenies wer...

Abstract Forty-five African or Asian origin pearl millet populations bred either in Africa Asia were investigated to generate information on heterotic pools. They clustered into seven groups (G1 G7) when genotyped, using 29 highly polymorphic SSRs. Fourteen parental representing these marker-based crossed diallel mating design 91 population hybrids. The hybrids evaluated at three locations Indi...

Epistatic interactions among quantitative trait loci (QTL) contribute substantially to the variation in complex traits. The main objectives of this study were to (i) compare three- vs. four-step genome scans to identify three-way epistatic interactions among QTL belonging to a metabolic pathway, (ii) investigate by computer simulations the power and proportion of false positives (PFP) for detec...

A full diallel mating design was used to hybridize seven pumpkin inbred parental lines, yielding 42 F1 hybrids, including reciprocals. The generated lines and commercial check hybrid were evaluated in two environments investigate the per se performances, combining ability effects magnitude of heterosis over mid-parent, better-parent hybrids for yield, yield attributed, sweetness, total caroteno...

The term diallel is a Greek word and implies all possible crosses among a collection of male and female animals. Hayman (1954a, 1954b) defined diallel cross as the set of all possible crosses between several genotypes, which may be individuals, clones, homozygous lines, etc. Diallel cross is most balanced and systematic experiment to examine continuous variation. The genetic information related...

Haloperidol is an efficacious antipsychotic drug that has serious, unpredictable motor side effects that limit its utility and cause noncompliance in many patients. Using a drug-placebo diallel of the eight founder strains of the Collaborative Cross and their F1 hybrids, we characterized aggregate effects of genetics, sex, parent of origin, and their combinations on haloperidol response. Treati...

Twenty-one F1 hybrids were developed from seven diverse parental lines of muskmelon (Cucumis melo L.) two horticultural groups, viz. inodorous and cantalupensis through half-diallel mating system evaluated at ICARIndian Agricultural Research Institute, New Delhi, during 2017 2018. The component variance for sca (σ2s) was higher than gca (σ2g) all the characters, except average fruit weight, whi...

A set of crosses produced by involving 'n' lines in all possible combinations is designated as diallel cross and the analysis of such crosses is known as diallel analysis. Such an analysis provides information on (i) the nature and amount of genetic parameters and (ii) general and specific combining ability of parents and their crosses, respectively. The two main approaches being followed for d...
