BMC Genetics, 2017 Background Quantitative traits are common in nature, but quantitative pathogenicity has received only little attention in phytopathology. In this study, we used 100 Fusarium culmorum isolates collected from natural field environments to assess their ...

Estimation of additive genotypic variance with the F3 of autogamous crops [PDF]
Heredity, 1989 The additive genotypic variance, D, estimated with the F3 of autogamous crops can be taken as an estimate of genotypic variance of its F∞-progeny. Two possible ways of estimating D are compared on the basis of their mean square error. For each of the two estimators the F3-population design, i.e., the number of lines, the number of plants per line and ...

Quantitative genetics theory for non-inbred populations in linkage disequilibrium
Genetics and Molecular Biology, 2004 Although linkage disequilibrium, epistasis and inbreeding are common phenomena in genetic systems that control quantitative traits, theory development and analysis are very complex, especially when they are considered together.

Genetic analysis of environmental variation [PDF]
, 2010 Environmental variation (V-E) in a quantitative trait - variation in phenotype that cannot be explained by genetic variation or identifiable genetic differences - can be regarded as being under some degree of genetic control. Such variation may be either

Tree species, tree genotypes and tree genotypic diversity levels affect microbe-mediated soil ecosystem functions in a subtropical forest [PDF]
, 2016 Tree species identity and tree genotypes contribute to the shaping of soil microbial communities. However, knowledge about how these two factors influence soil ecosystem functions is still lacking.

Genotype and Phenotype Coefficient of Variance in Maize (Zea mays L.)
International Journal of Environment and Climate Change, 2022 The present investigation was carried out with 30 maize inbred lines at Seed Research Technology Centre, Rajendranagar, PJTSAU. Analysis of variance revealed significant differences among the inbreds for all the traits studied. The phenotypic coefficient of variance (PCV) was slightly higher than the genotypic coefficient of variance (GCV) indicating ...

An R package "VariABEL" for genome-wide searching of potentially interacting loci by testing genotypic variance heterogeneity [PDF]
, 2012 Background Hundreds of new loci have been discovered by genome-wide association studies of human traits. These studies mostly focused on associations between single locus and a trait. Interactions between genes and between genes and environmental factors

Genetic variability studies for yield and yield components in sunflower (Helianthus annuus L.)
Electronic Journal of Plant Breeding, 2016 Genetic variability is a crucial tool for improvement of seed yield in sunflower. The analysis of variance of 23 hybrids revealed significant differences for all nine characters studied.
