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.

Analysing D.suzukii monitoring data, an initial population level lower than the last three years was revealed, followed by a population increase in June that necessitated an intensification of insecticide interventions on late varieties.

From 3D LiDAR flower quantification to price elasticity and retail margins in Washington, California and Canada, this analysis explores how pollinators, seasonal supply constraints and in-store strategies shape cherry volumes, pricing dynamics and long-term market value.

In Spain’s Ebro Valley, early cherry harvest will start on April 15. Covered crops show resilience despite unstable weather, while uncertainty remains for mid and late varieties due to rain and wind during flowering.

The new Cheery Glow cherry developed in Chile combines early harvest, high quality and low chill requirements. Earlier than Santina and with strong postharvest performance, it opens new commercial opportunities and supports market diversification worldwide.
