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.

Between 2021 and 2022, researchers at the University of Georgia conducted field surveys to study the North American native parasitoids of Drosophila suzukii. A total of 371 Drosophila parasitoids were collected through the deployment of sentinel traps consisting of fruit baits.

The British cherry season faces extreme heat and yields at 70–80% of a normal crop, while fruit quality remains high. England's harvest falls to five weeks, as Scotland extends UK supply into September and the market continues to benefit from solid consumer demand overall.

A Hungarian study on two sour cherry cultivars shows that the growing season affects bioactive compounds more than cultivar or farming method, influencing polyphenols, anthocyanins, flavonoids and antioxidant capacity and highlighting the importance of harvest timing.
