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 use of fludioxonil is authorised for post-harvest use but a growing body of evidence casts doubt on its classification as 'low risk' and the scientific community is calling for a re-evaluation.Consequently, possible alternative solutions are being explored.

The first Spanish greenhouse cherries reach the European market with very limited volumes and prices up to €80/kg. Strong demand from the Netherlands, Scandinavia and the UK, while the open-field season may start later than usual, impacting exports.

A study on 22 sweet cherry cultivars in Zaragoza examines how warmer winters affect dormancy and flowering. Declining winter chill alters phenology and threatens yield, varietal adaptation and long-term sustainability in Mediterranean growing regions.
