The only plum I have never had crack is Santa Rosa.

Plum Cracking
The biggest yield loss I have in my plum orchard is cracking of the fruit. I live in Vermont (near zone 5, plums for 15 yr) and regularly have dry spells followed by very wet weather. I have seen cracking on essentially everything, including peaches ,in really bad conditions, but with a huge variability from cultivar to cultivar.
Since I am continually adding to my orchard, it would be nice to be able to compare cracking between cultivars.
If people could add in thier experiences, we could develop a relative cracking index which would help a large number of people.
Since every year is different, as well as when in the ripening sequence the adverse weather occurs it is hard to make an absolute scale. So I have averaged how often I see significant damage. For example Pembina cracks readily, and only in 1 year so far has it not had >50% of the fruit cracked, where as alderman only has significant losses in really bad years. Some of my results may be due to the variety not being “ready” to split or limited number of years they have fruited so getting a broader field of experiences is important
If anybody has a better idea on how to do this please let me know.
