Genotype-by-Environment Interactions and Adaptation to Local Temperature Affect Immunity and Fecundity in Drosophila melanogaster
Natural populations of most organisms harbor substantial genetic variation for resistance to infection. The continued existence of such variation is unexpected under simple evolutionary models that either posit direct and continuous natural selection on the immune system or an evolved life history "balance" between immunity and other fitness traits in a constant environment. However, both local...
متن کاملLong-term Laboratory Evolution of a Genetic Life-history Trade-off in Drosophila Melanogaster. 1. the Role of Genotype-by-environment Interaction.
Trade-offs among life-history traits are often thought to constrain the evolution of populations. Here we report the disappearance of a trade-off between early fecundity on the one hand, and late-life fecundity, starvation resistance, and longevity on the other, over 10 yr of laboratory selection for late-life reproduction. Whereas the selected populations showed an initial depression in early-...

Genotype-environment interaction for plant breeders has been important as it is a complex issue in breeding for high yield varieties and releasing new genotypes. In order to assess adaptability and stability of sunflower varieties in different climate conditions, twelve cultivars were investigated in Karaj, Shiraz, Birjand, Kashmar and Arak in randomized complete block designs with three replic...

In order to evaluate oil yield stability in oilseed rape genotypes and genotype´environment interaction, 22 oilseed rape genotypes were evaluated using RCBD design with 4 replications in Agricultural Research Station of Islam Abad-e-Gharb during 3 cropping seasons in normal and delayed sowing date conditions. Combined variance analysis showed that genotype, environment and genotype´environment ...
متن کاملEvaluation of Grain Yield Stability and Genotype- Environment Interaction of Barley Promising Lines in Warm and Humid Regions of the Country
In order to investigation of genotype - environment interaction is essential for selecting compatible and stable genotypes in plant breeding. For this order analysis of genotype × environment interaction and identify barley stable genotypes for warm and humid regions, this study conducted in a randomized complete block design with 4 replications and 16 genotypes with two check cultivars in ...
