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 plants were set up according to the chosen form of cultivation, in comparison with the traditional spindle, starting from one-year old rods. From the analysis of the data collected, some interesting indications for vegetative and productive aspects emerged.

In Germany, per capita consumption of cherries and sour cherries fell to 1.7 kg in 2025, while national production rose 33% thanks to favorable weather. Spain, Greece and Italy remain key suppliers, supporting both fresh fruit sales and industrial processing.
