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.

Cherry production is shaped in autumn: irrigation, stored reserves and dormancy affect bud fertility and winter-chill response. Orchard data help estimate crop loads and plan winter pruning, guiding timely decisions on fruit size and next season’s yield in each orchard.

A Ukrainian study tests hydrocooling in three sweet cherry cultivars and one sour cherry cultivar: water at 1°C with organic acids, cooled to 2°C near the pit. It preserved positive indicators and cut negative impact by up to 49.73%, with effects varying by cultivar.
