The clones of the GiSelA® series are the most widely used rootstocks in cherry cultivation in temperate climates. GiSelA® were obtained from a genetic improvement programme carried out at the University of Giessen, Germany. The aim of this project was to obtain a series of rootstocks with gradual control of tree vigour: dwarfing, semi-dwarfing and medium vigour rootstocks.
Among the major advantages of using GiSelA® are excellent earliness of fruiting and high productivity, good graft compatibility with both sweet and sour cherry varieties, regular branching with a wide growth habitus, good winter frost resistance and virus tolerance.
Obviously, the cultivation management of cherry trees must be adapted to the needs of GiSelA® clones: as they are very fertile rootstocks, they require early and regular pruning in order to ensure sufficient vegetative renewal. In addition, they require high and constant water and nutrient inputs in order to ensure good fruit quality combined with high productivity.
Below is the report of Johannes Feldmann, Director of the Consortium Deutscher Baumschulen - CDB, presented at the workshop on cherry varietal innovation at Macfrut 2023.

Complementary to the application of cytokinin to enhance stage I of fruit growth and improve caliber, the other important stage when defining fruit caliber corresponds to stage III of fruit growth and development where the hormone responsible for this process is Gibberellic acid.
