Morphological data showing continuous distributions, polygenically controlled, may be particularly useful in intergroup classification below the species level; an appropriate distance analysis based on these traits is an important tool in evolutionary biology and in plant and animal breeding.--The interpretation of morphological distances in genetic terms is not easy because simple phenotypic d...

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.

This study aimed to estimate the combining ability, of T. cacao genotypes preselected for drought tolerance through diallel crosses. The experiment was conducted under greenhouse conditions at the Cacao Research Center (CEPEC), Ilhéus, Bahia, Brazil, in a completely randomized block design, in an experimental arrangement 21 x 2 [21 complete diallel crosses and two water regimes (control and str...

Exotic germplasm (i.e., beyond the breeder’s target area) has traditionally been used to broaden genetic base of local (germplasm within populations, but little done assess gains that could be induced by this breeding practice in sub-tropical regions Africa. Here, eight maize (Zea mays L.) inbred lines developed from pedigree crosses exotic and sub-tropically adapted lines; STALs) were inter-ma...
