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.

France expects more than 30,000 tonnes of cherries this year, around one third above average. Growers are urging consumers to buy more, while hand picking, short shelf life, pest pressure and rising orchard costs keep retail prices between €5 and €8 per kilo in June.

UPA-UCE and Asaja urge the Extremadura government to launch an emergency plan for cherry growers in northern Cáceres after storms caused losses above €20 million, destroyed harvests, cut farm income below production costs and exposed major gaps in crop insurance today.
