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.

Chile is by far the largest cherry exporter globally, exporting 414,000 tonnes of cherries from November 2022 to February 2023. By region, Europe is the largest producer of cherries and accounts for 32% of global production.

A study from China shows that pre-cooling sweet cherries at 4°C can reduce cracking by over 50%. Cultivars Jiahong and Hongdeng react differently, but both benefit. Physiological and genetic data support the effectiveness of this low-impact postharvest solution.

South Africa is strengthening its cherry industry and aims to access the Chinese market by the 2026/27 season. With earlier harvest times than Chile, expanding planted area, and growing export potential, it could become a key supplier during weeks of limited global availability.
