MUTATIONS

ABOUT A NEW MUTATION


Discussions with MM M. Coppejans and R. Vanden Berghe

An original article written for this site by Doctor Alain Campagne whom we thank. The Webmaster

In 1998, Mr Vanden Berghe got, by chance, a Lineolated Parakeet female of an unusual colour. Although she was out of two normal green, it was a very diluted colour but, according to him, different from pastel birds and more like GoldenCherry Roseicollis. Mr Vanden Berghe tried unsuccessfully to breed from her and so he decided with his friend Mr Coppejans to let him try and breed from that female. She was successfully paired there to a Cobalt male and after a few months had five good eggs. When the chicks were fully feathered the breeders were happily surprised to discover some diluted colours in that first generation. There were different diluted colours and some normal «wild» colours among the chicks, it meant that it was a co-dominant inheritance. Regarding to their colour they were named «Golden».

These birds of first generation were also paired to Cobalt birds, and after some months they were lucky to get again chicks from several clutches. When these were fully feathered, besides the diluted colours, similar to the first ones, they discovered a very pale bird that appeared to be a «silver» colour. After showing his birds and discussing with several experts, Mr Coppejans agreed that the mutation could be related to the co-dominant Edged Fisheri mutation and adopted the name «Edged» in spite of Mr Vanden Berghe's preference for the Golden and Silver names.

It is a melanin reduction of 50% on the body and the wing coverts, but those are centrally diluted while the edge of the feather retains darker colour causing the «edged» effect.. This makes the «green» birds looking a light green, almost yellowish, and the «blue» birds becoming a light bluish grey with grey marking. These colours slightly vary from one to another bird and in various parts of the body. However I noticed that some Lineolated show a brown and even a pale brown edge effect which is not only a melanin reduction but also an alteration into brown melanin, which could sound a bit different from the edged Fisheri's definition.

As a co-dominant inheritance, we can have simple factor and double factor edged birds, the latter being very clear (light). The very first Double factor edged Lineo appeared two months ago. It is a DF Edged Olive bird with a beautiful colour, I would say a brownish yellow colour named «Bruine» by the breeder.

Adding the edged factor to the colours Green, Dark green, Olive, Blue Turquoise, Cobalt Turquoise and Mauve Turquoise, will give a large range of colours, some being already shown by the breeder. The co-dominant inheritance makes it faster to get the new colours, but I want to point out Mr Coppejans'ability, taking the greatest care and time to build a strong healthy line without inbreeding. According to him, he will need one or two generations more in order to get a better knowledge of this new mutation that could be, according to Mr Vanden Berghe, a bit different from the Edged Fisheri, and could bring some surprises.

If we agree with the "Edged" name, then, there will be Edged Green, Edged Dark Green, Edged Olive Green, Edged Blue Turquoise, Edged Cobalt Turquoise, and Edged Mauve Turquoise Lineolated Parakeets, each colour with Simple or Double factor. That is to say, twelve new colours ! ! !

Perhaps these are not the final names, probably less attractive that the «golden» and «silver» but they could be internationally understandable by referring to a mutation and correct colour names already known.

The best birds will have the strongest wing marks, so it is not good to breed the Edged mutation in combination with any other dilute mutation or Ino.

This new mutation discovered and carefully bred in Belgium (as were the very first Lutino and Cobalt) will shortly put the Lineo in the foreground again.
