In the fall, I bought one plant of Elan F1 with intension to propagate runners. And while it has not grown any runners yet, when it opened its first blossom, I tried pollinating with pollen from the White Soul blossoms that were available just so it would set fruit. At the time, I effectively CROSS pollinated the open White Soul blossoms with Elan as well. I have continued to cross pollinate two more Elan blossoms with White Soul’s.
Well, that blossom did set fruit, but has been growing this giant ugly-looking fruit, and THOSE new ones are also looking odd. Elan F1 is supposed to bear red conical fruits — these look like over-grown pink Alpines.

AND the White Soul berries are starting to develop into rounded fruits with red seeds!
Only explanation I can think of is that Crossed traits might show up on strawberries right away rather than not being obvious until offspring of the fruit seeds — maybe because their seeds are on the outside? I’m thinking of corn as an example of fruits that show crossed traits immediately.
