Sex-linked Recessive Mutation

Red (opal)
1,0 opal

As is well known Australians for breeding a large amount of color mutations gained thanks to catching bird mutation from their natural environment. In fact vivid mutations in nature occasionally appear. It is caused with the fact that natural environment eliminates such copies. Bird about special coloration is easily visible and thus becomes a potential object of attacks by predators. Finding the partner also an aim of the procreation is difficult. Mainly colored naturally birds avoid “variant spices”. In case of opal eastern rosella however this outline of the nature effect was shaken. The first mention about copies caught opal rosella comes from 1837 year. Then Mr. P. Gould categorized “new” birds as the separate kind and called them Fiery Parakeet (Ignatus Platycercus). Popularity breeding of the red mutation eastern rosella in Australia stated in seventies of the last century. In the same period she turned up in Europe (1978 Germany). 1,0 opal At present it is a very popular mutation. Interesting is the fact that in small groups still it is possible to observe opal specimens in their natural environment constitutes the curiosity. Evidence it about great vitality of this mutation in nature.

In the opal mutation red psittacin spreads in relation to yellow. Bird has the entire red belly, breast and thighs. Specimens sometimes occur which have smaller or large amounts of yellow psittacin in places where only a red dye should appear. Even though such a spotted belly or breast in the opal mutation is a defect, some breeders like it. Beak, legs and claws kept their natural color. The bird tail can be different shades of colors from greenish-blue to pink-red. On the back depending on the specimen characteristic for rosella standard “golden coat” was replaced in the bigger or shorter rank by the red color. Intensity of color red is an individual feature of species. Other feature of this mutation is the fact that males have a white band plumage under the wing which is characteristic for standard females. The difference is that at opal males and females it is wider.

Cinnamon
0,1 cynamon

In France the cinnamon mutation turned up in 1965 but in Australia was recorded in the nineties. In this mutation production black eumelanin was stopped at the stage of the brown color. The blue color on wings was lightened. Green is also paler. At individuals a difference of color intensity exists in this mutation. Skin on paws birds, claws and the beak slightly were lightened. Curiosity is that at young mutations cinnamon an effect of so-called red eyes appears. Chicks hatch with red eyes which with time are darkly. About the fifth day lives are already dark.

The cinnamon mutation gives a lot of opportunities to create interesting color combinations

Lutino (SL ino)
1,0 lutino

Probably for the first time in Europe this mutation was brought up by Mr. Gerhard Rubesam in 1984 Germany. In Australia initiation breeding of the lutino mutation took place in the nineties years, based on birds caught from nature.

0,1 lutino

In this mutation eumelanin practically was eliminated from plumage and tissues of the bird body. Disappearance of black dye caused also reduction in the blue and green color. Green and black plumage passed into the yellow color, blue into the white color. Birds kept psittacin – pigments red and yellow. Lutino is practically yellow bird with red head and breast and whites pinion. Birds have red eyes. Beak, legs are “flesh-colored”, pale claws, transparent. 0,1 lutino Intensity of the yellow color depend on specimen can be changeable. From brightly yellow to dark with delicate coat dirty green. It is caused by different degree of the eumelanin reduction. Sometimes also come across birds which in different places have a single red or black plumage. The cause sticks in short reduction of given dye.

At present a few interesting combinations of this mutation with other mutations, among others from cinnamon (lacewing) and opal (rubino) were brought up.
