What is hybrid vigour?

[Smokin Moose]

When two inbred lines from diferent origins are crossed and the resultant progeny produce a better yield or quality due to a better balance of genes, that is hybrid vigour (heterosis). Not all crosses are an improvement on the parents. Random crosses among random lines will give you random results. Hybrid vigour results when the parents used express favorable specific combining ability.

Hi! i have questions about F1 Hybrids... if i get F1 Hybrid seeds with vigor, the only way to preserve that vigor is by cloning? if i stabilize a strain that came from an F1 Hybrid, will i get something very different than the original one with vigor? is it worth it?(to have a stable strain from a plant that once had vigor)
