I think hybrids are very important in genetic research and establishing what is related to what. However the mix of closely related subspecies can be very wrong as you loose essential genetic purity.
Mutations are nice to look at and used in laboratories how ever mutations again pollute genetic viability when their "weak genes" are mingled with healthy populations.

Personally I am strongly against both.
Hybrids are a risk to the purity of bloodlines and with many populations of amphibians now in steep decline it is even more crucial that we keep species pure.
As for mutations what do you mean? Colour morphs or genetic mutations?
Colour morphs I have no problem with as long as they are not caused by hybridisation although they are mostly bought about through inbreeding which means that the genes are pretty poor causing more developmental problems.
Genetic mutations such as the glow in the dark Silurana I am against as with hybrids they are a risk to the purity of the species.

To be fair, i am quite interested in natural hybrids, of which there are many, particularly amongst the Ranidae. Europe alone has more than 5 that i know.

I don't mind natural hybrids and have kept a number of hybrid Bombina bombina x variegata as well as Rana esculenta, it is hybridisation of animals in captivity that I am against.

I keep a colony of "Green Frogs" probably a mix of esculenta, lessonae and ridibunda and sell them as "edible or Green frogs, this i don't think is bad as it is only possible to maintain a kl. hybrid with the presence of a parent species, or preferably both!
