Pecan seedlings infected with rose mosaic virus?

[Kay Young]

My neighborhood pecan tree propagation specialists (squirrels) have gifted me with many pecan tree seedlings. A number of them look healthy but have a peculiar design on the leaves which looks very much like the rose mosaic virus. I know almost nothing about growing pecan trees. Is this leaf pattern familiar to any of you pecan tree experts? Does it indicate something about the pecans that were planted or about my soil (that I am pretty proud of)?
Thanks,
K
