Effects of genotype and environment on breadmaking quality in wheat
Background: It has long been recognized that bread making quality traits vary considerably as a result of genotype, environment and their interaction. The present study was aimed at determining the effect of cultivar, environment and their interaction on several bread making quality traits as well as to analyze relationship between these traits, Methods: Hundred forty wheat genotypes originated...
متن کاملParametric model based assessment of genotype×environment interactions for grain yield in durum wheat under irrigation
The objectives of this study were to assess the genotype (G) by environment (E) interaction of grain yield of durum wheat(Triticum durum Desf.) based on parametric models, additive main effects and multiplicative interaction (AMMI) and joint linear regression models; and compare the relative efficiency of the two models in explaining the GE effects. Twenty-three genotypes were evaluated across ...
متن کاملGenotype-by-environment interactions influencing the emergence of rpoS mutations in Escherichia coli populations.
Polymorphisms in rpoS are common in Escherichia coli. rpoS status influences a trade-off between nutrition and stress resistance and hence fitness across different environments. To analyze the selective pressures acting on rpoS, measurement of glucose transport rates in rpoS+ and rpoS bacteria was used to estimate the role of F(nc), the fitness gain due to improved nutrient uptake, in the emerg...
متن کاملA molecular investigation of genotype by environment interactions.
The fitnesses conferred by seven lactose operons, which had been transduced into a common genetic background from natural isolates of Escherichia coli, were determined during competition for growth rate-limiting quantities of galactosyl-glycerol, a naturally occurring galactoside. The fitnesses of these same operons have been previously determined on lactose and three artificial galactosides, l...
متن کاملHeterosis associated with genotype-environment interactions.
SE of hybrid vigor is of great importance in terms of present-day agricultural production. For example GARDNER (1968) states: ". . . Development and use of heterosis has been the most important practical achievement of genetics so far. The monetary value of the increase in corn production due to use of heterosis for a single year has been estimated to exceed the total cost of federal research f...
