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 greenhouse was built in 2019 and the micro-grafted cherry trees were planted in 2020. The goal is an early harvest, which will take place between 10 and 20 May and should reach a production of 20 tonnes/hectare in the early part of the European season.

In addition to influencing the distribution of assimilates, the removal of a portion of spurs during the dormant period improves the distribution of assimilates among a smaller number of fruits, thus facilitating a more harmonious relationship between growth and fruiting.

Optimizing water efficiency in cherry production is essential for sustainable agriculture. Strategies such as Regulated Deficit Irrigation (RDI) improve yield and crop resilience in a context of increasing water scarcity worldwide.
