Genotype-by-environment interactions affecting heterosis in maize
The environment can influence heterosis, the phenomena in which the offspring of two inbred parents exhibits phenotypic performance beyond the inbred parents for specific traits. In this study we measured 25 traits in a set of 47 maize hybrids and their inbred parents grown in 16 different environments with varying levels of average productivity. By quantifying 25 vegetative and reproductive tr...
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...
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 کاملPhysiological Processes to Understand Genotype × Environment Interactions in Maize Silking Dynamics
Variation in maize yield across environments often reflects genotype-specific responses in crop-flowering dynamics. The most widely observed effect is the temporal separation of male (anthesis) and female (silking) floral maturity, referred to as the anthesis–silking interval (ASI). Many studies have shown that maize yield also is a function of crop growth rate around flowering. At present, how...
متن کاملGenotype-environment interactions at quantitative trait loci affecting inflorescence development in Arabidopsis thaliana.
Phenotypic plasticity and genotype-environment interactions (GEI) play a prominent role in plant morphological diversity and in the potential functional capacities of plant life-history traits. The genetic basis of plasticity and GEI, however, is poorly understood in most organisms. In this report, inflorescence development patterns in Arabidopsis thaliana were examined under different, ecologi...
