Otto (S)
Sweet cherry, Prunus avium
Interesting variety that ripens directly after 'Regina'. The very attractive fruits have good size and convince especially with their high cracking resistance. Otto (S) is not prone to overcropping and is easy to pick because of its long stalks and the even distribution of the fruits. The high cracking resistance allows for a long picking season. To achieve ideal fruit and aroma qualities the fruits should ripen on the tree.
