Do coral champagne cherries need pollination trees?

At present, there are many kinds of cherries, including small cherries and big cherries ((sweet cherries and cherries)). Small cherries don't need to pollinate trees. A tree can bear cherries, but big cherries can't. There are several self-pollinated varieties of big cherry, such as Rubins, yellow honey, Steiner and black pearl. Most varieties are cross-pollinated and need to be matched with pollinated varieties.

Coral champagne, like Turella, is cultivated by the University of California. Champagne is a large fruit variety that has not been registered. This variety, produced in Taian, Shandong Province, matured from May15 to May 20, with a pinkish peel and an average fruit weight of more than 12g. I feel that the quality of fruit is better than that of Binku. The suitable pollination tree is Brooks or Binku, which is 4 days earlier than Brooks and 1 1 day earlier than Binku. The refrigeration capacity of coral champagne is about 400 hours.
