Size-controlling rootstocks for sweet and sour cherries
GiSelA®3 Gi 2091(S)
Rootstock for very intensive
cultivation.
GiSelA®5 Gi 1482(S)
The most important dwarfing cherry rootstock in Central Europe.
GiSelA®6 Gi 1481(S)
the productive size-reducing rootstock.
GiSelA®12 Gi 1592(S)
the alternative to GiSelA®5 Gi 1482(S) and 6 Gi 1481(S).
GiSelA®13 Gi 14813(S)
The less demanding rootstock.
GiSelA®17 Gi 31817(S)
The most vigorous clone, adapted to replanting.
For intensive sweet cherry growing in temperate conditions, the GiSelA® clones are the first successful and economically important dwarfing rootstocks. Production, marketing and rights for these rootstocks, which originate from a breeding program at the university of Giessen (Germany), are assigned to CDB (Consortium Deutscher Baumschulen), an association of German nurseries.
The three most important clones GiSelA®3 Gi 2091(S), GiSelA®5 Gi 1482(S) and GiSelA®6 Gi 1481(S) are – as well as GiSelA®13 Gi 14813(S) - hybrids of the crossing Prunus cerasus "Schattenmorelle" with the species Prunus canescens.
GiSelA®12 Gi 1592(S) originates from a similar crossing Prunus canescens with Prunus cerasus “Leitzkauer” and GiSelA®17 Gi 31817(S) is an offspring of the crossing Prunus canescens with Prunus avium.
The 6 GiSelA® clones show a different level of size-reduction compared to Prunus avium (mazzard, F12/1).
According to soil, cultivar and cultivation intensity, the best adapted clone can be selected. In-vitro propagation produces homogenous plant material of high quality with initial strong growth, which is reduced to the clone-specific level with the beginning of cropping.
A definite advantage of the GiSelA®s is the early beginning of cropping. First yields from the second leaf on and full crop from the 4th year on guarantee a quick return of the invested capital. The high productivity is maintained over many years. With adapted cultural management methods, fruit size is not negatively influenced.
Especially positive is the high adaptability of the GiSelA®s. In comprehensive trials and commercial orchards, no or only few tree losses occurred.
Other beneficial traits of all 6 clones are flat branching and broad growth habit, no suckering tendency, excellent winter hardiness, tolerance to pollen born viruses, and very good compatibility (healthy budwood provided). According to preliminary experiences, replanting after P. avium does not cause severe negative effects.
As the rootstocks induce a high yielding potential, early starting, regular pruning has to assure, that each year sufficient shoot growth and leaf area are built up for fruit nutrition.
