Probably, though I don't know what exact temperatures trigger the condition, so a tree in a warmer microclimate might produce doubles when a tree of the same variety elsewhere might not. I believe the full information is in Temperate Zone Pomology by M.N. Westwood.

Lon,
So the inherited trait is variety specific, as opposed to tree specific?
Thanks,

Doubles are an inherited trait that is triggered by higher than usual temperatures at bloom time. "Bing" cherry will produce a lot of doubles in California's central valley, but almost none here in the NW. Dr. H.P. Olmo grew out seedlings of Bing and selected some that resembled Bing, but produced a much lower percentage of doubles. At least one was released under the name of Brooks.

I have notice an anomaly that is interesting. About 20% of the plums are doubles.
Is this a normal occurrence for plums or could it be a result of the previous 
year's trauma?
