You're right,
@jmorth. It highlights any found cultivars. Any words in that field that don't have a cultivar match are simply presented as text with no clickability.
Now, if you have a custom seed and pollen parent and you want to put them into into this new Parentage field, you can do that. Just put both in there with a " x " between them. I'm not sure which goes first.
You can experiment with it and see how it goes.
Lynn: The seed and pollen parent field that you have in the databases that you moderate are still there and won't be touched. But if you want to copy that information into the Parentage field then you will start to enjoy the benefits of that field. I would suggest that we do migrate that information over at some point.
