New Genes: The Black and Blue Roborovski

I’m so proud to have imported agouti pied and possibly blue agouti pied roborovski from Holland and Germany via Houten towards the end of last year. As soon as possible I shared one of these hamsters with Vectis Hamstery for the purposes of exploring the new colours black and blue. Excited because, if it’s the same blue as with other species, you cannot have that without black (blue colour is usually dilute + black).

I’m even more proud to have bred black pieds out of two of these robos. Something that was possible thanks to Tebbe Bonder of Bonder Exotics and Daniella Ringling or Piccoli Amici for letting me import these and thanks to Vectis Hamstery for getting on board with breeding them. I’ve handled breeding new colours by myself and it’s no fun!

So far it looks to be behaving as expected but with new genes it’s important to keep an open mind. I’ve bred mine to make more of the genes available to us. The plan is for one of us to breed unpatterned agouti’s carrying the genes. These agouti hamsters will, hopefully, produce black, or blue (or both) and this will prove it’s recessive. If both parents do not show the colour (the phenotype) but produce it in their offspring then the gene cannot be dominant.

Unpatterned blue agouti hamsters will suggest it’s a dilute gene and we will also like to see what a self colour looks like without a pattern as no one knows for sure what markings a self roborovski would have. Close examination of the fur would be needed to ensure it’s the same colour to the roots. If it isn’t it will raise more questions that can be answered with more sensible breeding.

Once recognised by the standards committee, then further breeding can be done with other varieties. What does a husky black look like? A husky blue? A dilute husky? But it’s important to take things a step at a time and only use the wild colour (agouti) to prove your case. You can’t have a black agouti, for example. If you don’t produce a blue agouti (the expected phenotype for the dilute gene), it suggests the blue is something else. Like a gene that is only a modifier that affects black.

In any case, it’s very pretty. I’ve been in total love with roborovski since I first started breeding in 2013 and, indeed, they were my very first litter of hamsters. I’m extremely excited to be working with this and it seems far more robust than the blue I have been working with in Syrians. Health can be improved but when the health is good to start with, it makes any project like this much better to work with.

We’re not jumping to many conclusions with this. We’ve only produced a couple of litters so far and there’s a long way to go yet. I’m enjoying the journey though!
