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.

Studied between Chilean and Israeli institutes have analyzed the function of pattern-triggered immunity in sweet cherry, induced by the fungal elicitor Xyn11/eix, was analysed. The results show that Xyn11/eix induces two distinct responses: cell death and ethylene increase.

Fungicides like Serenade Aso produce a series of natural compounds with specific activities on pathogens and plant defense. Lipopeptides and antibacterial compounds typical of the strain break down cell walls of fungi and bacteria, causing death and preventing contamination.

A study from Chile proves that controlled atmosphere with 10-15% CO2 and 10% O2 extends Regina cherries' shelf life up to 40 days while preserving quality and flavor—an effective solution to improve logistics for long-distance exports, especially to Asia.
