A new large-scale sequencing and phenotyping experiment of hybrid rice varieties leads to associations with genetic determinants whose mode of action was revealed. Heterosis, or ‘hybrid vigour’ as it ...
When two homozygous plant lines with different characteristics are crossed, the resulting offspring are often more robust and productive than their parents. This phenomenon is called heterosis. It can ...
Few studies quantify evolutionary processes in populations of domesticated plants in traditional farming systems. In February's Ecology Letters, Pujol, David and McKey show that these systems ...
When two homozygous plant lines with different characteristics are crossed, the resulting offspring are often more robust and productive than their parents. This phenomenon is called heterosis. It can ...
Inbreeding depression is the reduced survival and fertility of offspring of related individuals. Large effects are documented in wild animal and plant populations, as well as in humans. Intercrossing ...
A new study of sorghum explores the genetics of heterosis, the process by which hybrid plants perform better than the parent varieties used to create them. The new study fills in some of the gaps that ...
Abstract: Early‐generation hybrid fitness is difficult to interpret because heterosis can obscure the effects of hybrid breakdown. We used controlled reciprocal crosses and common garden experiments ...
When a movie star is billed as having “it” or “oomph,” what she probably has is heterosis (hybrid vigor). At least, that is what Geneticist George D. Snell says. In the current Quarterly Review of ...
Heterosis can be separated into two basic types: direct and maternal. Direct or individual heterosis is the effect of hybrid vigor in the crossbred offspring. Performance traits normally improved in ...
