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 management of ESPAGRY IBÉRICA needed to digitise part of the production process and opted to purchase a machine with artificial intelligence. The cost of the machine was partially subsidised by the regional government.

Predicting sweet cherry hardiness is crucial for frost management, as early spring development makes them vulnerable to late frosts.

Cracking in sweet cherry fruit can lead to total crop loss. A Ukrainian study highlights genetic and morphological causes, showing how variety and ripening time affect split types. Cultivars like Mliivska žovta, Mirazh and Amazonka showed the best resilience.

A detailed study highlights how high-pressure humidification in cold storage rooms significantly reduces cherry dehydration after hydrocooling, preserving fruit quality during post-harvest storage and before packaging, even in heterogeneous conditions.
