1. First year:
We choose two pairs, two combinations of an opaline cock and a pastel hen. We need this two pairs. We should avoid to narrow genetic relations when we are mating the offspring.
Combining an opaline cock with a pastel hen is better then a pastel cock with an opaline hen because of the sex-linked inheritance of the opaline factor.
Result: wildtype cock, double split and opaline hen split pastel.

2. Second year:
We mate the double split cock from one pair with the opaline hen split for pastel from the other pair.
Result: opaline-pastel cocks and opaline-pastel hens. Our goal is reached but he percentage of this new colour variety ( 8%) is low.

3. Third year:
Use the split opaline, split pastel cock and the opaline-pastel hen. With this choice we avoid change of splits and combinations of red eyed birds.
Result: opaline-pastel, cocks and hens. But the percentage is higher. All the offspring we can use in further developing of a strain.

Comments:

The name opaline-pastel makes clear that the characteristics of the pastel and the opaline are combined. The mutation factors M-d (distribution is changed) and M-r (reduction of the eumelanin) are involved. The opaline factor and the pastel factor both influence the deposition of eumelanin. The factors are laying on different chromosomes. The M-d factor inherits recessive, the opaline factor inherits sex-linked. The colour of the eyes is red. It is better to avoid eyesight problems. Combining two red eyed birds is not the best choise..

In this overview we see a lot of combinations that are useful to build a good strain. The light yellow gives the good combinations. The dark yellow gives the best combination. The best results give: Cock1 x hen 2 and cock 2 x hen 1. Opaline-pastels and good opaline, split for pastel.

It costs many years to build a good strain. Very important is the choice of birds of a good quality. When you want to breed opaline-pastel with intensive red pigmentation, you have to select them. The colour is a combination of (bleached) brown pigment, red pigment and yellow pigment. Selection in the red direction is done since the start in 1972. The extension of the red pigment in the wings and tail can be influenced by selection because of the intermediate heritage. Also the colour intensity can be stimulated by selection . But it is also possible to breed a more yellow specimen.
