Michigan State University evaluated dozens of sour cherry crosses for their potential as cherry rootstocks, resulting in the Corette® series of precocious and productive dwarfing to semi-dwarfing rootstocks and several semi-vigorous, less precocious rootstocks.

Weigi rootstocks are crossings between GiSelA- and Weiroot-clones. Further trials started in 2004 on 4 different locations in Germany and France. After few years testing and some positive results, decision is taken to propagate them invitro in Italy and start making trees.

The selection of these interspecific rootstocks was made on basis of the induced tree vigor and tolerance to environmental stresses like drought, flooding, frost and pH content of soil. At present seven Krymsk rootstocks have been patented and have been commercially released.

In Serbia, sour cherries are a traditional fruit type grown on 19,551 ha. A study conducted by the University of Kragujevac in Čačak probed the suitability of seven clonal rootstocks and one seed rootstock (mirabolan) grafted with the sour cherry variety 'Šumadinka'.

Since 2017, the MSU team has been comparing the performance of early dwarfing rootstocks (all from the Corette® series), developed by the university itself, with reference rootstocks Gisela 5, Gisela 12, Gisela 3 (sweet cherry only) and Maxma14.

The objective of the research was to evaluate the performance of the cultivar '0900 Ziraat' grafted onto the semi-vigorous rootstocks Krymsk, Gisela 6 and Piku 1. Four breeding forms were applied to these cultivar/rootstock combinations: VCL, SSA, UFO and KGB.

Regarding rootstocks, one of the most promising approaches to increase plant resistance to viruses is post-transcriptional gene silencing, which employs RNA interference (RNAi) to prevent pathogenicity and virus replication.

The most important factor in spindle formation is to maintain the dominance of the central leader. The central crowns can be cut back in the future, after the formation of fruit-bearing branches below the crown ends.

As part of this project, 3 demonstration plots were created between 2021 and 2022 at the Universities of Concepción, La Frontera and Austral de Chile, with 10 cherry rootstock selections, plus 2 commercial controls: Gisela 12 and Colt.

The trials, Stoppel points out, were very promising, particularly for four clones (Weigi® 1, Weigi® 2, Weigi® 3 and Weigi® 4), which were registered, patented and commercially licensed. The license for in vitro propagation was awarded to Vitroplant of Cesena, Italy.
