In this study, conducted in two different seasons, we aimed to choose parents to obtain promising segregating populations for the extraction of black bean (Phaseolus vulgaris L.) lines that are superior in terms of disease resistance, plant architecture, and grain yield. Twelve parents were arranged in two groups to compose a partial diallel in a 5 x 7 scheme. Group 1 was composed of parents wi...

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...

Abstract: In many agricultural crops, the number of parents used in cross breeding make it difficult to obtain all possible hybrids diallels. Therefore, using maize as a model plant and based on traits with high low heritabilities, aim present study was quantify correlation estimates general combining ability (GCA) specific (SCA) between complete diallel circulant diallel, without inclusion par...

With the aim of estimating genetic parameters and identifying superior popcorn combinations, 10 parents were crossed in a circulant diallel and evaluated together with the 15 resulting hybrids at two locations in two growing seasons for grain yield, number of broken plants, number of partially husked ears and popping expansion. The hybrids were less sensitive to environmental variations than th...

Combining ability and gene action for quality and nutrient uptake of okra (Abelmoschus esculentus L.) were studied following full diallel mating analysis using five pure lines viz. IN-1048, Clemson spineless, Punjab selection, 1936 and IN-97 as parents under wastewater condition. The experimental lay out consisted of in CRD in full diallel cross mating in the research area of the Department of ...

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...

Populations were developed as intergradations among three maize cultivars, two adapted to North Carolina and one to Mexico, with the objective of testing whether diallel information could be used to identify the relationships among populations. The data substantiated theoretical observations that the technique would identify relationships among populations resulting from recent intergradations.
