The first experiences with cherry breeding at the VSUO in Holouvosy in the Czech Republic date back to the late 1960s. The main variety selected from this programme is Kordia, which in recent years has become one of the world's leading varieties in the medium-late ripening period, mainly due to its high fruit quality standards.
The primary objectives of the WSUO programme are cherry quality (size, texture and colour), resistance to cracking and rot, shelf life and plant productivity. MAS technologies are used in the breeding programme for the early selection of genotypes on several traits: self-fertility, spring frost resistance, drought and climate change tolerance and low chilling requirements.
WSUO, besides Kordia, has commercially propagated 28 cherry varieties. The best known are Early Korvik, Christiana, Felicita, Irena, Justyna, Kasandra, Tamara, Techlovan, Tim and Vanda.
Below is the report of Lubor Zelený, cherry breeding project manager at WSUO in Holouvosy, presented at the workshop on cherry variety innovation at Macfrut 2023.

The innovation of this method is the use of a portable device designed to produce cold plasma and a plasma-treated solution. 15-45 seconds of cold plasma exposure prior to grafting on fresh sections of scions and rootstocks increases root collar diameter and growth length.

Heat, mild winters and late frosts are pressuring cherry trees in Italy. Shading nets can reduce water stress and thermal damage, but their effect on yield depends on rootstock, vigor, training system, canopy density and orchard management from bloom to post harvest too.

In cherry trees, adequate chill accumulation is essential for uniform bud break and flowering. Hydrogen cyanamide and bud-break agents help manage dormancy, advance harvest timing and improve fruit quality, pollination, fruit set and overall orchard performance.
