albino raspberries!

[peanuts]

We have had  a dry and hot start to the summer.  And this year our cultivated blackberries (from a vigorous unknown strain we inherited when we moved to our Hertfordshire house 33 years ago, and years later brought out to France) have had their best ever season. 
It has been a bit on the hot side for our Autumn Bliss raspberries, but we have been enjoying them since the end of June!  Yesterday we picked from one of the canes a handful of 'albino' raspberries, and clearly there are more to come.    It isn't sun-scorch, as that usually affects just some of the bobbles. They are perfectly ripe and sweet and juicy. 
Anyone else had albino fruit?

How very interesting!    Could be from a bird dropped seed, although what a coincidence right in your raspberry patch?  Or a mutation.  Enjoy and be sure to mark the cane they come from, to see whether those will go on producing albinos next year.   Isn't nature marvellous.

Can't really believe it is from a bird-dropped seed.  it is in the double line of canes, right next door to others.  Just the one cane though with these white berries.  Interestingly the blackbirds seem happy to try these as well as the red ones!
I will mark the cane though, good idea.

Autumn Bliss had a "sport" which was yellow some years ago, It is now on the market called "All Gold " so your plant is now repeating history
