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.

Meda™ varieties have been evaluated in Europe for three seasons now. All have been selected with a minimum of 35-40 days post-harvest. Meda™'s is the only breeding programme that has used postharvest as a selection filter.

It is important to be able to quantify or have a reference of the reserve content accumulated post-harvest. The analyses most commonly used by the industry to determine the accumulation of reserves are the arginine content in roots and the starch in darts or floral structures.

A field trial in a cherry orchard in Izmir, in Turkey’s Aegean region, shows that bumblebee pollination with Bombus terrestris improves cherry size and weight. Results highlight larger fruit, fewer cherries per kilogram and higher profitability for export-oriented growers.
