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.

In China, researchers studied the cherry cultivar “Luying 3” and found that applying abscisic acid (ABA) improved fruit ripening by enhancing color uniformity and hormonal balance. The treatment also reduced harvesting steps, improving labor efficiency in the field.

Cherry orchard covers are proving essential in Chile: they mitigate climate risks, boost yields by up to 30%, and allow earlier harvest. An effective solution for early varieties like Santina and Nimba, exposed to frost, rain, and thermal stress.

Lizard skin in cherries affects fruit appearance during cold storage and export transit. The Chilean study compares varieties, ripening stages and postharvest behavior, identifying the cultivars most exposed to damage, the most tolerant ones and key risks for local exports.
