In 1966 or thereabout, Professor Tailbal of Italy discovered Ivory. This same mutant appeared in stock bred in Louisiana by Julius Tribodeaux and is rapidly gaining in popularity. Of pearl white or beige coloring, there again appears some variation, to pale Fawn. Quite unusual, the ring is nearly black. Squabs have medium down upon hatching. With genetic experiments thus far, it appears recessive.
The albino mutation was imported from M. Tange of Japan by Dr. Miller in 1967. Somewhat delicate as is usual with Albinos, it appears rather similar to White yet has no pigment, having pink eyes and is clear of pigment under the tail. A recessive mutant with no sex-linkage involved. It is short-downed upon hatching.
The above mutants cannot be the limit. Work is already being done to produce a Bull-Eyed White. AS most dove breeders are aware, other combinations have been produced. Although it is quite possible to make a lot of pure breeding varieties from all these known mutants. It is less restrictive and more entertaining to make all sorts of matings and learn what makes the wheels go around. Every mutant can be considered a building block for making combinations. It is easy enough to put them together, and in two or three generations produce Peach Pied or Albino Silky, for example.
Some breeders attempt to produce as many combinations as possible from a given pair. At least 16 is possible, and this figure can be magnified further. Others attempt to selectively breed for less obvious variations such as larger or smaller size, protracted cooing, or ‘setting’ the pattern on Pied. So far these have been pretty slow, difficult, and not much rewarded. Maybe in the future there will be more competition along these lines. Some selection for disease resistance may be very helpful because doves tend to be more delicate than pigeons.
