AMMI Analysis of G X E Interaction in Finger Millet Genotypes for Yield Stability and Adaptability

Indian Journal of Dryland Agricultural Research and Development, 2016
Multilocation yield trials on fifteen early duration finger millet (Eleusine coracana Gaertn.) genotypes were conducted under early and late transplanting condition at Bhubaneswar and early direct sown condition at Berhmpur for three years during kharif season.

Search for a gene x environment interaction: G x E hunt.

Genetic epidemiology, 2000
We developed a method to identify gene x environment interactions (G x Es). To test this method in the simulated data (Problem 2, GAW11), we first identified an environmental factor (E1) that was associated with the simulated disorder. We stratified affected sibling pairs (ASPs) into two groups, those concordant for the presence of E1 and those ...

Investigation into the presence of genotype by environment interactions (G×E) in Scottish Blackface lamb traits

Small Ruminant Research, 2012
Genotype by environment interactions (G × E) can form a potential source of inefficiency in animal breeding if selection decisions are made without acknowledging their effects. The presence of such interactions between two Scottish hill farms was investigated using performance data collected from 18,459 Scottish Blackface lambs between 1997 and 2010 ...

Sample size requirements for indirect association studies of gene–environment interactions (G × E)

Genetic Epidemiology, 2007
AbstractAssociation studies accounting for gene–environment interactions (G × E) may be useful for detecting genetic effects. Although current technology enables very dense marker spacing in genetic association studies, the true disease variants may not be genotyped.

Screening for blast resistance in rice using AMMI models to understand G x E interaction in Guyana

Phytoparasitica, 2018
In rice, totally one hundred and three genotypes were evaluated for resistance against blast disease in three hot spot locations of Guyana. The experiments were conducted in spring and autumn seasons of 2015, 2016 and 2017. The modified upland blast nursery (UBN) method was adopted for screening blast resistance.

AMMI, GGE biplots and regression analysis to comprehend the G x E interaction in multi-environment barley trials

Indian Journal of Genetics and Plant Breeding (The), 2016
The present study was carried out to ascertain the stable genotypes, environments discrimination and genotype by environment crossovers using different stability models. In AMMI ANOVA, genotype x location interaction implied substantial variation (17.61%) and IPCA1 and IPCA2 altogether captured 65.72% of the interaction mean squares, whereas, in GGE ...

Breakpoint Model for Logistic Regression and Application to the detection of G x E Interactions

2016
Introduction : Complex diseases are known to be highly heterogeneous in nature. This heterogeneity can be due to various factors including genetic heterogeneity (eg: population stratification), phenotypic heterogeneity (ex: clinical diagnosis of schizophrenia), exposure heterogeneity to various environmental factors (eg: alcohol, drugs, pollution, etc.)

QTL for yield in bioenergy Populus: identifying G×E interactions from growth at three contrasting sites

Tree Genetics & Genomes, 2007
Populus is a genus of fast growing trees that may be suitable as a bioenergy crop grown in short rotation, but understanding the genetic nature of yield and genotype interactions with the environment is critical in developing new high-yield genotypes for wide-scale planting.

An exploratory model for G×E interaction on hippocampal volume in schizophrenia; obstetric complications and hypoxia-related genes

Progress in Neuro-Psychopharmacology and Biological Psychiatry, 2010
Smaller hippocampal volume has repeatedly been reported in schizophrenia patients. Obstetric complications (OCs) and single nucleotide polymorphism (SNP) variation in schizophrenia susceptibility genes have independently been related to hippocampal volume.
