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.

China's cherry production will increase by 6% in the 2024/25 season, reaching 850,000 tonnes. However, imports are expected to increase to 420,000 tonnes this season, mainly due to marketing efforts by exporting countries.

Strigolactones strengthen postharvest defenses in sweet cherries against Botrytis cinerea. Research on the Xianfeng cultivar shows that 0.1 μM reduces gray mold, lesion development and fungal biomass by activating phenylpropanoids, flavonoids and defense proteins.

Managing frost damage in cherry trees requires action from dormancy breaking through vegetative growth. Preventing ice nucleation, protecting cell membranes, and controlling Pseudomonas and bacterial canker can help preserve orchard health, resilience, and productivity.
