"The super millionaire fruits of the Alma Mater": this is how Corriere della Sera headlined years ago when announcing the results obtained by researchers from the Department of Agri-food Sciences and Technologies of the University of Bologna on the cherry tree genetic improvement project: the seven Sweet® sisters, the new varieties named after the children or loved ones of their inventors.
