The aim of this study was to evaluate the efficiency of yield stability analysis models and to assess genotype × environment interaction effect on grain yield of 20 durum wheat genotypes for identifying high yielding and adapted genotypes by BLU and AMMI models using experimental data of four cropping cycles (2009-2013) in five filed stations in warm rainfed regions of Iran. The results of Like...
To evaluate the genotype × environment interaction and determine the stable genotypes of wheat, 30 genotypes of bread wheat along with two controls namely Chamran and Chamran 2 were studied in 6 locations (Ahwaz, Darab, Dezful, Iranshahr, Khorramabad, Zabul) and two years (from 2013 to 2015), in each using an alpha lattice design with 4 replications. The results obtained from AMMI analysis dem...
Sweet potato breeding in Africa, more especially Nigeria, has mainly focused on improving productivity farmers' fields and fresh root consumption. In order to target the program, study was conducted estimate magnitude of genotype × environment interaction (G E) select stable high yielding sweet genotypes for yield Cylas severity two locations, identify most discriminating representative test en...
The objectives of this study were to analyze genotype by environment (GE) interactions effects on the forage yield of 8 corn hybrids by computing AMMI analysis and evaluating genotype (G), environments (E) and GE interactions using stability parameter i.e., AMMI stability value(ASV) and Wrick,s ecovalance (W2i). Experiments were conducted at five regions (karaj, Neysahbur, Gorgan, Brojerd and...
BACKGROUND A relationship between the serotonin transporter gene, adverse events and onset of major depression has been reported. AIMS To replicate a gene x environment interaction in a cohort with longitudinal data for life events, experience of depression, parental bonding and neuroticism. METHOD At the 25-year follow-up, genomic DNA was obtained from 127 cohort members (mean age 48 years...
As genome-wide association studies grow in popularity for the identification of genetic factors for common and rare diseases, analytical methods to comb through large numbers of genetic variants efficiently to identify disease association are increasingly in demand. We have developed a pattern-based data-mining approach to discover unlinked multilocus genetic effects for complex disease and to ...
Quantifying genotype × environment interaction effect and yield stability under different environmental conditions is very important challenge in plant breeding programs. The aim of this study was to quantify genotype × environment interaction effect on grain yield and grain yield stability of barley promising lines in temperate regions of Iran. Nineteen promising barley lines (G1-G19) along wi...
A model of genotype-environment interaction in quantitative traits is considered. The model represents an expansion of the traditional additive (first degree polynomial) approximation of genotypic and environmental effects to a second degree polynomial incorporating a multiplicative term besides the additive terms. An experimental evaluation of the model is suggested and applied to a trait in D...
