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.

Between 2021 and 2022, researchers at the University of Georgia conducted field surveys to study the North American native parasitoids of Drosophila suzukii. A total of 371 Drosophila parasitoids were collected through the deployment of sentinel traps consisting of fruit baits.

A Holovousy study in the Czech Republic examines 35 sweet cherry accessions and highlights the role of genetics, dry matter and ascorbic acid in resistance to surface pitting, a key issue for postharvest quality, shelf life and market value.

In sweet cherry, productivity starts in the previous cycle: floral induction, bud differentiation, reserves, irrigation and canopy management influence flowering, fruit set and quality in the following season, making post-harvest care decisive for stable yields and premium fruit.
