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.

Australian cherry production is forecast to fall 15% in 2026/27, to 17,000 metric tons after a winter with fewer chill hours. Exports are expected at 4,000 MT, while dry conditions and high irrigation costs could add pressure for growers in Victoria and New South Wales.

A three-year survey of 222 orchards in O’Higgins, Chile, validates a rapid Leaf Disc Assay to identify sweet cherry cultivars with lower susceptibility to bacterial canker caused by Pseudomonas syringae, supporting faster and more sustainable breeding decisions today.
