Evaluation
The very attractive fruits of this medium late ripening variety have good baking qualities even when premature. Top (S) yields high and regular and is not prone to biennial bearing. This secures a consistent supply for wholesale in this late ripening period. On dry sites there is a tendency to grainy flesh around the stone. The susceptibility to bacterial canker and Valsa infection should be taken into account when choosing the right site.
